So... Big news. In my opinion at least. I went all out on an exhaust, finally. After a lot of research and help from you all, instead of buying a sub, I bought an exhaust! I found some great deals on some subs... But then I got to thinking: a sports car needs performance mods, more than it needs sound mods. Besides, with the bass turned up, and when I have those 2 8" stock subs going, I have all the bass I need.
After a lot of research.. I went with the Quicksilver exhaust. It was between that, alta, and a couple others, but between the 20ish pounds shaved off and the 30+ bhp added on from the exhaust, I went with that. I'll post some pictures up and a video, but all I know is it's a gorgeous exhaust. And it sounds pretty damn good too.

 

dats a lota horsepowers....

 

Not to be the bearer of bad news but...

Dont tell anyone that ANY** exhaust gives you 30hp's

 

So, whats the pipe diameter?

 

Yeah.....

30 bhp... no!

 

Once yo vtak kicks u gets like 60hp bro! Nah j/k 30 is way blown out of proportion yo might get 10 if your lucky.

 

Just let us know how bad it droans on the road. The Inveida was horrible. Unbearable at 75mph... Sounded fantastic at wot, but who the hell could live with it for the rest of the time?

 

30 HP from an exhaust and stock 8" subs? Aha, you're not talking about a MINI then! Pontiac G8 maybe?

lol, kidding. But really, you have stock 8" subs?

 

Ive had the QS exhaust for almost 2 years now...sounds great, very little drone on hwy and light when compared to stock.

Definetly does not increase hp what so ever...

Also, only started to drone after dp was replace with catless.

 

Me. And everyone else that has an Invidia and loves it....

 

You can get 30hp from a cat back system. Hell, I got 10hp and 10Tq from my CAI.

 

I've got the Quicksilver exhaust as well.. It sounds AMAZING, everyone loves it and it is pretty intimidating. However, I agree with some of the other posters... It definitely does not add 30+ HP... maybe a few at best. (I've yet to dyno my car). And as far as drone, it does on the highway a bit, but I have found that you can easily mute it down by UP-shifting and letting off the accelerator a little to a steady angle to maintain speed.

 

It definitely added some power... don't know if it's 10 or 30, but it feels A LOT more powerful when I'm approaching 4,000 RPMS. Trust me, I wasn't believing it too much at first, was doing it mostly for sound, but this thing hauls *** now. Plus you can hear that turbo all the better...
Yep, and it sounds amazing. My friend's 5.7L GTO V8's magnaflow exhaust is quieter than my Q.S. catback, and mine is much deeper doing a side by side comparison, according to the about 10 people who were crowded around our cars. I mean this thing looks and sounds so good. It gurgles when it's just sitting there, then when you step on the gas, beautiful. Absolutely stunning. Just enough noise on the inside, and rolling down the windows is the cherry on top. As for the drone... none unless I'm going XX. I did notice that when I had the sports button pushed driving on the highway, it did make an INCREDIBLY loud drone, but when I switched it off, no drone at all.

And to the poster about my subs, yep. I had 2 8" subs stock, one on each side right behind my seat. They sound good. I've got the upgraded sound system in the mini and I'm really impressed by the bass response.

I'll do a dyno to see for you all. I am getting some sort of CAI soon, so that should add some more HP to the mixture. >

 

Don't get to excited about that dyno or you will just be dissapointed. I got have a alta intake and had a 2.5 inch straight pipe from turbo back and got it dynoed. 162 to the wheels, The air fuel was Fubar. unless you have a tune the ECU will try and compensate for every bit of it.

 

x3

lololol. I wasn't going to post, but I can't help it.
Its all too funny. The V8 must be out of gas cuz theres no way a i4 will be deeper than a v8 with an exhaust (at least one thats not 1" diameter).
Any friend's V8's I'm next to when we're on the throttle and I can't hear my own car at all.
2 8" subs, factory, you're thinking about the 5x8's in the back, with the bass turned all the way up blaring at 90+ mph hitting bumps on the highway/back roads doesn't mean its bass.
The sport button, turning on and off drone, lololololol. Do you even know what the sport button does? Before you say it changes the car and adds 25hp when you have it on.... it increases throttle and steering response. Try going WOT (wide open throttle, or slam your foot to the floor), with and without the sport button on, and tell me if theres a difference in "drone".

lol sorry for coming off like an ***, but the statements made in this thread are ridiculous.

Please show the dyno. I'll rip off my magnaflow exhaust and buy a QS exhaust when its legitimately proven to add 30 hp with no tuning.



(honestly, i'm sorry. I'm really not usually like this but I've had a boring day at work and can't keep myself from voicing my comments)

 

Are you kidding? Bored at work or not, that was completely unnecessary.
Unless you come down to Louisville and see my car, I don't think you have any room to talk. Honestly. You assume I'm lying on every point I hit on? No, I'm not. What would be the point in lying to a forum full of people I don't even know? I don't care about impressing you all, I'm just trying to post something so I can talk to people who are interested in the same thing as me.

-YES, I do have 2 8" subs stock. If you stand on the outside of my car, with the subs turned on +3/6, it flexes the outside of the car, the whole thing. I had 3 15" subs and 2 12" subs in my past 2 cars, I think I know what subs sound like, look like, and what they do.

-YES, it is deeper than my friend's V8 GTO WITH A MAGNAFLOW. I heard it myself, it sounded BETTER, and DEEPER. This rang true with 10 of my friends huddled around the car, and they are car freaks, every single one of them. They all said it.

- SPORTS BUTTON: Yes, I'm fully aware of what the sports button does, I'm not mentally challenged, as you pose me to be. If you want to come down to Louisville and I'll prove to you how wrong you are. AT 90+ MPH, WITH IT ON, THERE IS DRONE. AS SOON AS I TURN IT OFF, IT STOPS. What the hell, why would I even lie about that...

No need for you to be such an ***, but assuming I'm lying about these things is ridiculous. You haven't even heard it, or experienced it in my car, so please don't assume you are completely correct when you have no idea. I was on this forum discussing what I HEARD from multiple sources that this exhaust adds 30 horsepower, I was just repeating what I heard. This is the first sports car I have owned, so honestly I don't know much about speed, and all this stuff yet, so I was repeating what I heard.

 

Okay Okay, maybe it was a bit out of line. But listen, we are just trying to tell you the truth here. Look at the above posts, they're all saying the same thing. I'm sorry if you can't handle the bluntness.

1. Please show me the MINI Build Option (OEM as you say) that includes 2 8" Subwoofers. One on each side next to your seat. Where is there room for 8" Subs with an enclosure next to your seat? I'll shut up when you prove this to me.

2. You're right. I have no idea what your friend's Magnaflow system on his GTO sounds like. So in reality, sure, it can definitely sound deeper than his 5.7L V8 GTO. Sorry for doubting this. Car freaks will know best.

3. Its a sport button, not sports. But okay, if you are going 90, with the sport button on, and have drone, then you turn off the sport button, the drone goes away. YES, but then you're NOT going 90 anymore. Like I said, the sport button changes throttle response, MEANING, when you turn off sport mode while cruising at 90, your foot position stays the same and you start decelerating. Of course drone goes away, because your throttle position has just gone from 60% (sample throttle position to cruise at 90) to 40%. If you have the sport button on and you give it 40% throttle equivalent, you won't have drone either. So, no, you're not lying, but like I said, we are all here trying to help you understand the facts. Like you said, this is your first "sports car" and you don't know about speed. I never actually said you were lying about anything.

4. Just because it sounds louder doesn't mean its actually faster. My guess is that since it sounds so much louder that it feels faster. Sounds can have an affect like that. I felt mine was faster too. I thought the same. But then I (like many others on this thread agreeing with me) went to a DYNO and found out I was making an additional 2 whp than a stock car. Not to burst your bubble, but that was with an intake too. And this is with my magnaflow exhaust that is pretty much a straight pipe back to the back box. Along with every other exhaust on this forum that people have installed and dynoed. If the QS exhaust was magical and made 30hp over stock, this wouldn't have been news now 4 years after the R56 has come out. I don't think you're an idiot or stupid at all. I just think you're misinformed.

Don't "repeat what you heard" as that will get you in trouble in life. But at the same time "It definitely added some power... don't know if it's 10 or 30, but it feels A LOT more powerful when I'm approaching 4,000 RPMS. Trust me, I wasn't believing it too much at first, was doing it mostly for sound, but this thing hauls *** now." doesn't sound like repeating what you heard. If you want to feel what a mini hauling *** feels like, get it tuned.

Look, all marketing for these aftermarket products are always blown out of proportion. EVEN when they show "DYNO PROVEN GRAPHS". A "cold air intake" has dyno graphs from a vendor saying it is proven to add 10 whp. Yet, any member that gets it and dynos it, sees 0 to little increase in power. Certainly NOT 10 whp. You can't listen to the marketing hype. If every member came back with a dyno graph showing 10whp gain, then yes, we can say its true. But its not the fact. Please have your car dynoed so we can see the results. I'd LOVE to see an exhaust that gains 30 hp above stock. Go research AFR (air fuel ratio) when you have a second. Expelling additional/higher velocity gases through the larger diameter exhaust will make more noise, but the stock ecu will never compensate enough extra fuel to make 30 whp. Maybe you have a magical mini. Again, bring the dyno sheets and I'll shut up.

 

Here is the dyno from my car with an open air intake and a full straight pipe. Dont expect anything better.

 

Well said.. I too looked for the OEM build option at www.miniusa.com and couldn't find the dual 8" sub option. It just has the H/K 10 speaker description. I know others that have the H/K system and they don't have any subs.

 

I'm assuming highschool. Heres my dyno. The before line was with my exhaust, intake, and sound generator delete. The after line was with my tune, which put my mods to work and adjusted AFR/fuel/timing, etc etc etc. Things that the stock ecu cannot compensate for.



Pre: 174 whp, 200wtq
Post: 208 whp, 232 wtq, @ 16.5psi. Now @ 19psi (need to dyno again)

 

This thread is so full of comedy....

RedandBlackMini....don't take offense to what BostonR56 said....

He wasn't saying you were "lying"....merely pointing out in a nice way that the things you are saying make you look like a fool. There are a lot of people around here that know their stuff, Boston being one of them. Poke around, participate, ask questions....you can learn a lot.

It's great that you're excited about your car, but you're going to be in for a shock if you think exhausts and intakes are going to give you the horsepower you've "heard."

Also, I had no clue that the MINI sound system came with 2 8" subs....lol . But I'm no audiophile . I know on the H/K system in the R53, they used the 2 rear speakers as subs when you had it in "electronic" dsp mode. However, they were not true subs.

 

Exactly.

I've already torn apart the stock audio system and replaced and rewired the whole car with a more capable/powerful head unit in the secret compartment, with remote, direct ipod hookups, aux, usb, etc. Speakers swapped, and inputs for subs added.

I also know subwoofers. I'm not at competition level, but 2000 watt rms total in 2 12" subs in my old Audi A6 wagon sure "flexed" the car too. Not sure of the "hip" terminology now a days in highschool. Then again, I'm only 23, but I've definitely grown since my highschool days.

 

Wow, you all are a tough crowd. All I was doing was telling you all about my new mod, obviously excited about it. I said in one of my posts that I don't care about the power increase as much as I do the sound, that wasn't my main concern, because this is a daily driver, not a car I track all the time. I don't know about this sh--, and you all seemed to take advantage of that fact by shoving it in my face. Last time I post here.
Thanks to the people who have helped me in my previous posts though, a lot of nice people here but I'd rather not get into all this again.

 

But he does have a pretty red car with a black roof and black wheels! That's enough for me...

Welcome to NAM RedAndBlackMiniS!

Consider yourself properly Hazed!

 

To the OP,

Dont take these things too seriously, but one thing you can do is self educate your self on what your doing so you dont become victim to marketing. Being around motor sports a Loooong time/wrenching for two years before i got in to my degree i can say that i have plenty to still learn. Just dont make claims that are not realistic because it causes the ripple effect. Dont tuck your tail and run, post some pics up and if you really think the exhaust is louder than the v8... emphasize it with a video! fearn a few moves before you jump in the ring and through a haymaker if you know what i mean.


PS: dont listen to your friends when they tell you about how much hp's their exhaust have given them until you see a dyno sheet... a lot of times its disappointing with a cat back with any vehicle.



Havent seen you around arlington, im in springfield and work over in merrifield
