From what I read in another forum about the 05 GTO exhaust, replacing the mufflers with stright pipes is a highly effective way to obtain a great sounding exhaust, and much cheaper. But I am going to start a new thread or see if anyone on this site has done this Mod. I seem to trust people on this forum more than the other ones.

I cut my mufflers off my 05,yea it sounds pretty mean especially above 4k.But it might be a little loud for some people.
