3" Duals
I am making alot of changes to the truck right now and exhaust is one of them. I did some porting on a set of 243's i had laying around and milled them .010, also using some .040 cometics. I made the heads look as close as i could to a set of Patriot stg.2 LS6's i took some pics of.
I also have the 228R-112, Fast 90 mildly ported/LS2 TB, Underdrive Pulley, CAI, Pacesetter LT's My exhaust at the moment consists of just comming off the headers (3" collector) with a 2.5" SBC collector reducer, back into a 2.5" dual in/dual out Magnaflow with built in X and regency tips welded to the muffler. Im thinking of going with 3" duals with x-pipe into the same muffler/tips combo! Using this x-pipe kit http://store.summitracing.com/partde...5&autoview=sku |
3" duals is too big. Dual 2.5" max.

Single 4" would sound sick on your truck.
I don't think dual 3" would be way to big for your truck, since it is a 5.7 H/C You might lose some low end. Have you looked into adding cutouts instead? |
he'll be north of 400 rwhp. I'd go with dual 3" myself. He's rcsb so he's lighter too.
