Hey guys I have a question for re doing the entire exhaust system I'm looking to redo everything with larger tubing,long tube headers and catback with the most aggressive sound and best performance possible. What product/combos would you recommend? (Sites would be handy but keep in mind I live in canada). Also a recommendation on a good high flow catalytic converter would be great. Right now I have a stock exhaust with the stock muffler replaced with a flow master super 10 and love it but live in a salty area and am looking to replace everything I can with stainless steel parts for help with rust. I have a short bed 2014 silverado z71 with the 5.3 (I am aware this may have already come up but I don't wanna read 80 pages of comments)
