What did you find with the before and after dyno runs? Can't leave us hanging notso5.

Mean **** sound especially at the track but not overly loud. No resonance at all.
And yes I did before and after dyno runs....

Hey Edwin,

Sorry to hear that the tips aren't symmetrical, is it a length issue or width? Width is adjustable, and length is to, to some extent (by angle of the X-pipe)

I loved the tone of the GMG exhaust and found it loud but definitely tolerable. My wife didn't like it.

She likes my Europipe better.

Kitw,

Not your fault bud. I don't think it's either issue with length or width. You can see in this pic where the left side has a closer tolerance to the top of the car than the left (see red lines)

With that said, I just got back from lunch with my coworkers and the car is a blast to drive now. It's just something when you can hear the turbos spool and hear the gurgle when you left off the gas

Def slightly annoying... but I'm ok with it. Just not worth it for me to worry about that slight annoyance (unless it's a very easy fix). Now if I paid full retail new for it, then yes.. I'd be bothered

I think that can be adjusted a little bit. If you loosen all the nuts on the turbo studs, you should be able to shake it about and get it even. It was very even on my car
