Remus makes one for the MCS. Here are 2 pics. I found some sound clips. They're on this web site.
I'd love to see dyno numbers here. Having the two exits of the mufflers point at each other is a no-no unless there are internal baffles in that center section. The exhaust pulses will collide and have heavy turbulence. They have to come out the tips based on being forced out, as opposed to flowing out via a smooth turn. I can't see any evidence of welds that would indicate an internal baffle to re-direct the gas.
If anyone has numbers, post em up! I'm real curious if the design flaw makes any real world difference.
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.
I'm curious too. I did the one-ball and with the MTH and the HAI, there was a very NOTICABLE difference in low end. Heck, I drove up the hill to my home (1300 ft in elevation in about 3 miles) at 1800 RPM in 5th! I'd never been able to do that. But this isn't really very quantified..... I'm sure my ass could use some calibration!

Randy posted it quite a while ago, I believe.

um like i said earlier ,I'm having this install done on Jan 6. for sound clips, go to post # 25 on this thread and click on the link.Also, I have been in touch with luifer(post #24) who has the system installed. He loves it!And yes, the system is not much LOUDER than stock, but quite different.
Which of the exhausts are emissions/CARB legal? Dinan seems to be the only one with info...albeit one state short of a 50 state emissions legal exhaust...probably my state, California. Damn.
Anyway, could ABT or someone add which are road and which are race use only? Not that you guys haven't put together an INCREDIBLY informative thread yet...
There needs to be a new ..controled environment recording of all the exhausts to get a real sence of the differnce in sound, all the videos are done in differnt conditions... its too back no companys have done this :P... oh well..right
I take it back......LOUDER THAN STOCK! (Can anyone give me a hint as to how to post a sound clip?) Butt dyno says that I have more HP, that the response is much smoother, and low end torque is increased.I'll post pics of the VERY cool pipes soon, they are quite different than what I had been led to believe,sorta like LARGE version of OEM ( with all the small perforations that Remus seems to use in most of their systems.) Initial response to this system is a rousing

How do most of you guys get away with not fulfilling these requirements?
I want to change my exhaust but want to comply with the law – What systems are legal?
Is it only the cat backs?
Or one ball?

Well us lucky ones in Florida don't have emissions testing of any kind so we can do what we want heheh

Or keep the stock system around. I did a one-ball, and I'm in CA, and TECHNICALLY I'm in violation of the law. My exhaust guy offered the resonator for me to take home, but I tossed it. I'm betting the stock tips, the Mini on what's left, and the standard education of the inspection staff will keep me safe!
But it you're really worried, get only 50-state approved stuff, or keep the stock parts to bolt back on, or just live with the law.
I'm not too worried, and I know that some of the mods make the car more efficient too.
I’m curious; if you were to do all over again, would you have done the one-ball, or purchase an aftermarket cat-back. Let me rephrase, was economics the main factor with your choice to do the one-ball?

The only thing I would have changed is that I would have done it earlier :smile: I'm very, very happy. There are others who want to change the sound to some specific sound, but I'm not one of them. It's lighter, it flows better, and I don't think you really need to spend the $ on a higher flow system until you've unlocked other parts of the airflow. On a $/ unit increase, I don't think you can do better than the one-ball, MTH and the Hot Air Intake. So that's what I did. Since the pully is about $400 with install, it's not as cheap, although I love that as well. I didn't do it because the total $ were cheap, but I couldn't see spending over $500 for such little gain from an exhaust system.
If I port my head, add a header and the like, I still think I won't get one. I could cut out the battery box, go with a 2.5" straight pipe to a flowmaster or the like. I think that would still be less expensive than an aftermarket system, and it would flow better than them all.
I don't think an audio clip is needed for the Borla Street system. Just listen to the stock NMS system, and you've pretty much got it. I will say, that I preceive the Borla to be quiter at freeway speeds and there is less 4-cylinder "buzz" from the Borla over the stock. This is the system MINI should have installed as stock. With the rear seats folded down or the windows open, I can hear a slight "popping" or "burble" from the exhaust when lifting off the throttle. This I never noticed with the stock. Oh, and by the way...the Borla mufflers are better hidden above the rear body work than stock, and the pipe tips look great and do not change color. The system "grows" when hot, so the tips stick out about 1/2" more until that long straight segment of stainless cools down.
I liked your review of your Borla Street Exhaust.
I am looking for a less restrictive exhaust than the stock and with a suttle but not noicy sound.
As much as I like the Milltek I am concerned that it is a little too noicy for around town driving.
Are you still happy with your Borla? Can the tips be adhusted so they do not stick out too far.?
Thanks,
danish
Would cutting the resonator out of the JCW exhaust increase flow, and maybe even power?
Modifying any exhaust system can potentially cause changes resulting in gain or loss of power and in increasing or decreasing exhaust loudness. What will occur is anyone's guess since no one has tested the changes before and after.
Removing a resonator would reduce weight and may lead to a louder exhaust note. There could be less restriction to flow but that would depend on the rest of the muffler design. What will you do if you found you have lost power?
Since the JCW exhaust is part of the JCW kit most owners would want to keep it intact (more value) along with their warranty.

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?
