they say 2" but i think at points of bends it gets donw to as little as 1 7/8s, its crazy sucky, upgrade to 2.75"-3" single or 2.25-2.5" duals

Thanks Joey
Im going 2.5 duals from the 3rd cat back replacing the 3rd catwith a magnaflow muffler. I want some room to expand for further mods. I dont think i will have any backpressure issues with that 1 7/8ths. When I swap to PI I will prob throw some headers on and remove that restriction.
Thanks alot
Will
