Gentleman, I am new to your forum, from what I've seen and read it seems pretty interesting. In december I purchased a 06 xlr, for my wife's x-mas present (really mine).3-30-06 was the first time driving the car, everything I read in this forum was true-mostly the good things!!! I was reading about the exhaust systems somewhere in the forum, now I cant find where it was? Can anyone help me make a wise choice? And does it void the warrenty? thanks guys hope to here from someone..
