I have a 3.5L 2005 V6 G6.. and , like your rotted through the middle pipe. I cut it out and welded a straight pipe.. and.. though it DOES have a nice deep tone at IDLE.. get a buddy to drive it with you outside.. and.. it sound RASPY as HELL! it sounds like a very bad ricer and I am looking forward to getting something put back in its place. anyone thinking of doing that PLEASE think twice cause it sounds awful when you step on it. any other options for what to put there?
