I had an aftermarket performance exhaust for a Miata and on the track it was great but on the street I noticed the lack of low RPM torque much more than I noticed the increase in high end HP. That said I have the BMW intake and exhaust. My wife also has a 128i but with stock intake and exhaust and I percieve no loss in power in my car. If anything the throttle response is better with no flat spots. I've never driven them side by side at high rpm's to comment on if there is a noticable gain there but I am delighted with my car.

I put the Performance Exhaust on the wife's 128i right after we picked it up at the dealer, and we both love it! Doesn't drone on the highway, and is mellow until you step on it, after which it really growls! What's not to like? Bigger "finisher" pipes look great, too.

In on this... My magnaflow should be coming in on Tuesday morning and on the car Tuesday night... I will time some third gear pulls and see how that goes... I don't think I will be able to get the car on a dyno in the next couple of days but I can see what I can do.
