RMA4

Sherkwerks by all means. i just put one on my car this past Tuesday by myself. It took about 3 1/2 hours. Fit is great and the sound is even better.

I have the GMG and love it. Great sound at idle/low rpm (great if you have neighbors or spouse who dont like it loud !) and a great cup car like scream at WOT. The GMG unit has larger piping and tips than stock and has a balance tube between the pipes to eliminate resonance. It is a very easy install (took me 2 hours without removing the bumper).
I am selling my stainless GMG unit (actually have 2, just got a polished one so plain unit is for sale). New they are $2100 + shipping, selling mine for $1895 including shipping and $120 in new clamps. PM with any questions.

Hey Michael, thanks for the feedback and also thanks for waiting! Good one and pat on the back for the DIY. It's not too bad to do which is unusual for Porsche
