what would result from adding a header system to a MCS with the stock exhaust system and an Alta intake? would not having an exhaust system affect the performance of the header system? what header system do you all recommend?
I'll probably do a dyno run with the resonator in, have it cut out, and have a straight pipe clamped in; dyno it again with the resonator out and see how it effects the power, if it is a power loss, I will just clamp the resonator back in. Do you really think it would effect the value that much?

There's also the issue of the adaptive tuning of the ECU, and the weight savings. Since you're dropping a bit over 20 lbs, you can have about 1-2 hp LOSS and still have the same HP/Weight ratio.

Think of all of these items as resistors in an electrical circuit. Taking out one resistor only really effect the circuit if it is a change in total resistance. So, you may get some benefit from a header without an exhaust system, but you're also probably not going to get the full benefit unless you have a less restrictive exhaust that can take advantange of the improved header.

ps, there is no agreed best exhaust. May have tone concerns, some with total volume. Also tuned exhausts can be tuned for many effects. So the questing is better asked "what is the best exhaust for XXX type of driving", and then you'll still get the answer I wrote

From what ive heard (pardon the pun ) the One Ball is just a louder stock sounding system.
My question is about the Borla. I want to get it, but im concerned it may be too loud. I liked the sound on the clip, but for thoes who drive with the Borla Sport, do you like the sound or is it a bit too ricey?
Thanks to everyone for thier great input and sound clips. Just a word about improved HP with exhaust changes. I don't think the major criteria for changing exhaust should be H.P. You don't get that much increase in most of these systems. Remember most of these published HP gains are sales oriented stats from the people who designed or are selling the systems. The testing is far from standardized and the cars are not standardized so comparing HP gains is really comparing an apple grown in Washintom to a pineapple grown in Hawaii. Doesn't make sense. Not every car tested came off the line the same year, they probably all have different mods and tweeks, the ambient temp/elevation/humidity was not standardized and you know the dinos are all different. Point is HP ratings are very subjective. In addition it doesn't take into consideration the changes in the torque curve of the car which for me was much more improved than HP with my Dinan set up. Just a lot wider torque cure, more usable torque all acrosss the range. No more low end stumble and a bit less downshifting around town. (To be fair, I admit I also have all the other Dinan Signature Series Mods on the car)
A word about the Dinan set up. No it isn't a remake of any other system. It is enginerred from the ground up to work with the mods sold by Dinan. If you don't improve throttle body diameter, air intake volumne and temp and ECU you can't optimize performance from an exhaust change. So unless you are going to increase those parameters, exhaust, in my mind, is about getting the sound you like and maybe a nice pairs of tips! (Hummmmm)
Anyway I like the Dinan cause it does't pop, just a subtle deep burble when you get out of the throttle. No drone on the hiway at all. I can listen to valium rock or clasical cello on the stereo at high speeds without interference from the exhaust and when I get into the throttle hard it will drown out Metalica at high decibels. A nice combination of Deep tones on a background of banshee like screams.
Downside to Dinan: Rt tip collects more soot than left tip, = darker inside
Fix= Spray inside of left tip with flat black paint. Picky-picky-picky
Lots of good systems out there. Go to meets/functions, listen to different systems and if poss. drive/ride in some to get real feel. Don't buy for advertised HP ratings. Buy for the sound, fit, finish, looks and gut feeling. Remember most of your time is spent not looking at it but listening to/feeling it from your drivers seat. Just my $.02 enjoy

I build/buy for the performance or weight savings. I've found that racy exhaust sounds come free if you design an exhaust for performance. Same with intake noise or whatever. Vive la difference....
Anyway, I think that you'll find that if you set performance (power, weight or handling) goals, that when you're done you'll have a car that looks aggresive, sounds aggressive and turns aggresively.
with this 02 cents of mine, and the two from you, we only need $2.96 more for a cup of Starbucks!

FYI, my exhaust is (later this week), OBX header, Magnaflow high flow CAT, 2.5" tubing, and muffler TBD (maybe resonator too, if it's too loud for my wife). Cooper lower valence too. This will cost less than a SS Cat-Back system..... Including the header!
hey by the way the borla race sounds great . what should i do next maybe intake does that make as big as difference as the exhaust made.
if ui get chance i will record the sound off my exhaust , how can i posted for people to hear? i can not hear the brola sound when i go on it . i do hear the part that there is a comperson made with all four exhaust standerd,borla street,quicksilverand magno..........thanks to every one..........
Since JCW exhaust is available from the dealer, it should be added to the file. For a base line comparison, it might be a good idea to have the standard exhaust on it as well. :smile:
Here's a link containing standard exhaust and JCW exhaust sound file.
JUST ORDERED MY BORLA RACE, THANKS TO THIS SITE IT WAS ALOT EASIER FOR ME PICK THE ONE BEST SUITED FOR MY TASTE. ALSO I CURRENTLY HAVE THE K&N TYPHOON CAI, BUT AFTER READING ALOT ABOUT ALTA SYSTEM , I'M WONDERING IF I SHOULD SWAP?
THANKS AGAIN THESE FORUMS ROCK!

>>THANKS AGAIN THESE FORUMS ROCK! do a search for the thread on hot air intake. very informative.

thanks for the 'sounds'. still sorting through the aftermarket choices... any chance of a sound clip from the mcs rspeed? so far my favourite is the milltek. thanks for the great job you have done.
Hey where did you guys get that the one ball system (cut up stock) only gains 1hp? http://www.fasttoy.com/fb18.html has a dyno done locally showing 9 hp. I want to do this soon on a dynojet and get before and after also to show any gains.
Remus makes exhausts for Hamann, AC Schnitzer, and Racing Dynamics (RD Sport) i think. good quality products but i don't like the sound of them much. and for the money i'd rather have full stainless, or at least polished stainless.
i have a quicksilver sports exhaust and sounds great....i get heads turning everywhere i go...and asking what exhaust i have....even other mini owners are surprise that a mini can sound like this. low rpms you get a deep tone purr....after 5,000 rpm its a woosh porsche like sound....its great i love it!
) the One Ball is just a louder stock sounding system.
