porksoda Posted March 19, 2012 Report Share Posted March 19, 2012 Dumb question I know but I am a new owner and want to put a catback on my SS. Right now it has longtube headers and a custom true dual exhaust with a H-pipe and Flowmasters dumped under the bed. I am curious if any catback for a 03-06 Silverado will fit or if it is different because of the AWD? I really want a Pypes but I'm sot sure if it will bolt up.

The_aSSet Posted March 19, 2012 Report Share Posted March 19, 2012 Why do you want to change it? Quote Link to comment Share on other sites More sharing options...
porksoda Posted March 19, 2012 Author Report Share Posted March 19, 2012 Personal preference really. Never have really liked the Flowmaster sound. That and being dumped it drones bad. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted March 19, 2012 Report Share Posted March 19, 2012 Why not just change the muffler back? Would probly be cheaper, just a thought, idk about the fitment Quote Link to comment Share on other sites More sharing options...
porksoda Posted March 19, 2012 Author Report Share Posted March 19, 2012 Well again this goes back to personal preference. All the piping is crush bent and I want to get all the HP that I can with the cam and everything. Also here local to me all I have available is cvrush benders so I'd rather buy a mandrel bent premade catback. Quote Link to comment Share on other sites More sharing options...
NTMD8R_SS Posted March 19, 2012 Report Share Posted March 19, 2012 Yes you can run a 4.8/5.3L ext.cab, cat back but you will also need to get the Y pipe. Quote Link to comment Share on other sites More sharing options...
porksoda Posted March 19, 2012 Author Report Share Posted March 19, 2012 Yea I figured I'd get the Y from Pacesetter for their headers. Quote Link to comment Share on other sites More sharing options...
