^ DO NOT HOLLOW OUT!

Hollowing out the cats will do nothing but waste your time. Cut the cat out, and replace it with a piece of 2.5" pipe.

 

wasn't going to hollow it out anyways, im having my exhaust guy remove the rear cats on friday, i cant wait to hear this thing roar. btw avfrog I heard your truck on youtube, that sounds mean as hell, and i love those air horns

 

^ HAHA thanks!

 

I live in maryland and have never failed the emissions and my entire exhaust system has been replaced. I have the full dynatech kit with a maggie siso exhaust system and they never say chit to me and I go to the emission station in howard county. All they do is ask you to pull your truck in and they hook up to your OBD2 port and then send you on your way. And my truck is not quiet.

 

yea I have dual flowmaster 40s with no rear cats now, 2 days and no cel so i think Im good lol
