3" let that thing breath. I had 3" on my 347 and made a big difference on the top and throughout the power band. There is no need to have to do exhaust twice just do it once and forget about it

2.5" is good to like 400 horses,3 inch will probably rob some of your bottom end power.How much horsepower roughly are you gonna have?
