I thought the OBX Down pipe was made for the OBX Catback

since it's a direct knock off of teh Supersprint exhaust...

Part 1 and 2 come with the Downpipe kit and 3 and 4 with the catback (minus the Cat and Resonator options SS provides)

or do u use only the first part to bolt to the stock exhaust?

 

I did some research. It seems that some cars get a loss of power with the CEL and some do not. I can handle the little light, but I don't want to deal with the power loss when it comes on. I guess I'll wait until there is a WORKING 02 Sim before I mess with a DP...

 

Hey guys,

I'm looking to get a catless DP to replace my catted DP and I couldn't justify paying for anything other than the OBX... I mean its just a piece of pipe right? Right now i still have the stock catback, so it should just be a direct bolt-on from what i understand.

Anyways, a couple of questions.

Seeing how I would need to switch to the stock DP for inspection. Will the stock DP go in and bolt onto that second OBX pipe? It would be a pain to have to change both each time.

Also, it looks like there is a lack of a flex pipe in this system... Is there something i'm not seeing?

And last.... Would it be beneficial to wrap the DP in something like this, http://www.summitracing.com/parts/THE-11152?

 

I'm woundering if you need a cat to not throw a code? Or can you run catless?

 

You'll throw a code. And mother nature is going to kick you in the nuts.

Additionally, you'll be cleaning the boot more often, sooty sooty carbon is going to be all over your butt.

 

I think you're over exaggerating with the soot comment. I've been catless for 8 months and soot on the boot is not an issue. The prince engine is already a low emission engine so I would never expect to see buildup on the boot.

 

I was just wondering cuz I have the borla cat back exhaust and I want a new header also but I do t want to screw my car up and I hate throwing codes.

What's the best cat for a good price? Or are minis picky on cheap parts? I've only had mine since November before it I had crap car not worth fixing up.

 

I mean I don't want to screw up my car

 

You're going to throw a code, with an aftermarket catless or most catted downpipes. The only DP I know that won't (most of the time) is the Exhaust Depot catted downpipe.

Mini's ECU is very sensitive.

 

Either way, mother nature will pay you back.

 

Mother nature will be paying back many more SUV, and other gas-guzzler owners before getting to Mini owners running catless.

Not to mention how long she'll be paying back BP for.

And you do realize that any gas powered car, even with cat's, doesn't exactly spew daisy's out of its tailpipe. So I guess mother nature will pay you back as well.

There's much more to how much harm you do to the environment than your mini having a catalytic converter. I'm pretty big into saving the environment, and I understand what you're trying to say, but there is a lot more to lowering your carbon footprint than just having a catalytic converter on your car. (Considering you're putting out CO2 with a cat, aka a greenhouse gas).

 

The point of the cat is to convert toxic gasses into something LESS toxic. If you don't have a cat or the cat isn't working properly, you're releasing CO, hydrocarbons, and NOx. All nasty stuff for the environment, and anyone standing around the car breathing in the fumes.

 

Go plant a tree

 

Actually, its just a matter of picking your poison. Having catalytic converters on your car is actually WORSE from a global warming aspect, but is better for smog. And vice versa. The catalytic converter converts those nasty NOx gases to N2O, and N2O is 300 times more powerful of a greenhouse gas then CO2.

The true solution is to switch to something such as hydrogen fuel cells, which could provide an overall cleaner energy. But since cost is always an issue, we'll see how long it takes for something like that to happen.

 

COOL STORY BRO.

If you have a kid, please have them sit behind a car without a catalytic converter and take in deep breaths. If not, pick anyone you might have any sort of affection for. Go ahead. Since it's not a big deal.

 

im sure someone has smoked a cigarette around your kid "Yeah.ThatsRice."....try telling him to put it out next time. think he'll listen? probably not. if you wanna go catless, go catless, its your decision. if you don't want to, then don't. its as simple as that. theres no reason to argue that somebody catless should be running with cats or vice-a-versa. its just a never-ending opinionated argument.

that is all.

 

You sound like a libertarian....

 

How bout you have that same kid sit behind a car WITH a catalytic converter and take in deep breaths....I'm sure it will have the same result.

 

haha i try

but i want this thread to be about the actual downpipe. not about children standing in back of cars inhaling exhaust fumes (which shouldnt be done regardless of whether the car has cats or not.) especially when minis have such low emissions anyways.

 

Yeah, except the fumes are carcinogenic in a catless system.

I mean, do whatever you want, your impact won't be as hard as a big SUV or a giant diesel truck.

We can argue all day about which is better, but bottom line is:

Cats = federally required for street use, and HEY! No fine involved!
Catless = federally outlawed for street, and HEY! Fines, 3k up to 10k! Federal offense, NICE! All for a little sound and what, 5 horses? Maybe 10?

High flow cats give you nearly equal performance, and your car won't smell like crap.

 

Unfortunately laws, a lot of the time, don't reflect what's best for the people, or the planet. The emission laws in the country are outdated, and were created before global warming was a known issue. Read my previous post, and the link. There is a good case for both sides.

Cats = global warming
Catless = smog

Pick your poison.

 

Oh but on a side note... which relates to the thread.

I received my OBX downpipe, jacked up my car, to find that the stock r56 exhaust is one big piece. In order to fit this downpipe i would have to cut between the 2nd cat and the resonator and weld the 2nd part of the downpipe in. On ebay where i bought the product, they advertised it as a "Direct bolt-on, no modification required".

Not exactly too happy... And i would consider cutting and welding, but the downpipe doesn't match up the same way the stock one does, so if i wanted to put my stock DP in, i would have to cut and weld the whole thing again.

So i'll most likely be returning this... unless you guys have any ideas

PS- Yes, in hindsight i should have checked up on how the stock exhaust went together. For some stupid reason i assumed it was in a few pieces, like most aftermarket exhausts are.

 

Breaking Federal law just isn't worth it in this case, the end doesn't justify the means. Maybe you would be doing your part to reduce global warming, but at the same time you're releasing carcinogens all around your car, and at idle, in the car.

There are good cases for both sides, sure, but it's Federal law. With a hefty fine.
The gov. rewards shops that snitch about tampered emission controls, and in some states (CARB states for a fact) if you're pulled over for a loud exhaust, the cop CAN look under your car and bust you on the spot, and CAN flag your car for possible de-cat.

Like I said, for a little extra sound and a few horses, it just doesn't seem worth the possibility of a $3k+ fine.

 

^^^^why are you trolling in this thread "yeah.that's right"? you are off topic and seriously need to go find a greener section of this forum to preach on.

anyone that sticks any kid behind a car is an idiot regardless of ULEV booshit. You don't think your custom magnaflow dp back exhaust that you want to do is going to emit more carcinogens?

The thread is about the fit and function of the obx dp, not about what federal law is and your personal feelings regarding the removal of a cat on a ULEV car.

so lets just review your want list here, and see about how green you really are.

1. you have a cooper S and not a base model. you are using more gas, and therefore hate mother nature

2. you are getting coil overs made in china.. Do we need to talk about china's manufacturing process and their environmental standards???

3. emm custom magnaflow exhaust... Are you going to have a secondary cat in that?...the answer "NO" as you clearly ask right here about removing secondary cat on your new custom exhaust.

This one link alone shows that you are nothing more than a troll.

https://www.northamericanmotoring.co...143-post1.html

Why oh why are you inquring about removing the secondary cat. Don't you know that it's illegal to do so?????

people like you really should just fall off the face of the planet.

Get out of this thread you pansy. you are off topic and contributing nothing.

 

Sorry dude. But secondary cat delete is NOT illegal. In fact, it passes CARB standards. The primary cat does 95% of the filtering. Removing the primary cat is NOT GOOD, it's effin' ILLEGAL.

And you are even more off topic than I am. You should have sent me a PM if you truly cared about the OP. At least I was talking about a part of the topic, you know, a "catless downpipe". This thread isn't called "Yeah.ThatsRice has a sh*tty opinion, I'm tough as *****".

I never said ANYTHING about being a totally green advocate. I would own an electric car if I did. But deleting the primary cat is just being ARROGANT.

And name calling ended in high school. Grow up.

I see people get on others cases about DELETING THE REAR WIPERS. PERFECTLY LEGAL, DOES NOT HAVE ANY EFFECT ON ANYONE AROUND THE CAR. But when I have an opinion on a mod that is both FEDERALLY OUTLAWED and TOXIC, I have to take personal attacks because of it? Give me a break. "Yeah, you can have an opinion, but it better be the same as ours, you pansy". You're the kind of person that makes this forum SUCK.

Sorry for having an opinion, I won't voice it anymore! I'll just fall off the face of the planet! I'm such a pansy
