AC SS Posted May 19, 2014 Report Share Posted May 19, 2014 What would you guys consider a better set up for 6.0 2005 single cab chevy with long tube headers mild cam tune no cats custom x pipe ...I plan on a supercharger soon Quote Link to comment Share on other sites More sharing options...
Tyson1972 Posted May 19, 2014 Report Share Posted May 19, 2014 2 3" custom tubing mid pipes to x-pipe to 2 3" mufflers to 2 3" custom tailpipes or turn downs. Quote Link to comment Share on other sites More sharing options...
BLOWN SS/T Posted May 19, 2014 Report Share Posted May 19, 2014 Some will say dual 2.5" is sufficent exhaust for what you have and maybe even with the supercharger. I'd personally run a full 3" mandrel bent exhaust or even a 2.5"/3" Quote Link to comment Share on other sites More sharing options...
JC03SS Posted May 19, 2014 Report Share Posted May 19, 2014 (edited) I'm with the 2.5" crowd. It's all gonna be free flowing. If you plan on some really big power I'd say 3". All open with 3" is like a wot setup in my op. Edited May 20, 2014 by JC03SS (see edit history) Quote Link to comment Share on other sites More sharing options...
f1ss Posted May 20, 2014 Report Share Posted May 20, 2014 I will say 2.5 unless going big power like stated. Just remember 2 mufflers and piping is twice the weight, about. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted May 20, 2014 Report Share Posted May 20, 2014 Exhaust size is all in how much power you plan to make and boost. If your not going to crazy stay with a 2.5. It takes alot of power to fully use a full free flowing 3 inch exhaust. Quote Link to comment Share on other sites More sharing options...
