M Performance Exhaust Impact on Performance
Hello,
For those of you that had installed the M Performance exhaust, has anyone of you noticed a difference in performance of your car? Either enhanced it or hindered it? I was under the impression that this mod is only for audio effect but was told that it makes the lag more noticeable? Tks! |

If anything I thought the turbo was a bit more responsive. I love mine.

I was considering a mpe but not so much if it is just to improve the sound. My next problem is if I were to install an aftermarket exhaust would the increase in performance decrease my fuel economy? If so I would have to stick with the mpe. LOL

No performance exhaust will add much as ours is designed almost perfect. You want some good performance get a BMS JB and maybe a downpipe. |

Turbos can benefit from a higher flow exhaust, but the main restriction is from the cat in the downpipe. You need a higher flow exhaust all the way from the turbo to see any substantive power gain, and you need a tune to really get the full advantage of it.

The stock exhaust, outside of the EPA mandated cat's, is pretty nicely sized...there aren't too many kinks I've seen when getting down below, which is probably why most aftermarket exhausts that aren't axle-back's are netting 10 whp over the entire range...
if I were to do it, like sean10mm was saying, I'd focus on the DP - getting a 200 cell cat will give you a lot of gains WITH a strong tune. I saw that on my Evo, turned up the boost with the stock DP, not too many gains...with a high flow cat, something like an additional 15 whp. That's CRAZY! (this is for a high boost evo, so probably not too comparable).

My M Performance exhaust is on the UPS truck for delivery today. I don't expect to feel any power difference but I hope it will be a little lighter and I know it will be audible, unlike my almost silent OE system. I really just want to hear my car, especially at the track. I have plenty of power for my skill level.

Just get a chain pipe cutting tool. If you don't have one, rent one from a autoparts store. |

I had the exhaust installed yesterday (didn't do it myself, $70 at the local muffler shop) and overall I'm very happy with it. As dd1981 said, it's NOT lighter but I love the way it sounds! It's deeper but not raspy. I can hear it now inside the car but it doesn't "drone". The best part (obviously) is when I get on it hard and click off full throttle up shifts........YES! It sounds awesome...every shift delivers a race car like snort between gears and downshifts sound even better. Someone said this exhaust is "a lot of money for some noise" but for me, it was money well spent. The stock car was just tooooooooo quiet. |

It was already on my car when I bought it and I can agree, it sounds amazing under hard throttle, the exhaust burble is music to the ears.

It's worth it, especially no warranty hassle. It's not intrusive at all and that's perfect. I think you summed it up nicely. Congrats Quote:

Hmmm was about to pull the trigger on one of these things, but now wondering if there's a benefit to getting the GT high flow downpipe and keep the stock exhaust.

Bear in mind a DP voids your warranty.
