Exhaust

[mark1223]

I was wondering if gm makes a true duel exhaust system for the 2007 silverado classic? If not, where can I cut it, so it will not void my emissions warrenty? Thank

the CAT has to stay for sure, that pretty much is the emission control lol

I plan on keeping the cat for the rumble, but I didn't know if I had to go collector back, or if I could cut it off behind the cats? Thanks. Some one had said, he thought gm made a true duel, but he thought it was around a grand, but all I have seen is a one into two. Thanks
