2.5" or 3" for Endurance Race
My Lemons car currently is set up with a 2.25" downpipe and exhaust. I am constantly removing the turbo and manifold for various reasons. I would like to redo the exhaust to v-band connections on both ends of the downpipe. I have a t3/t4 turbo with 90+ manifold and stock wastegate. I run about 12 psi of boost. I don't ever really plan on huge boost as it is for endurance racing.
Should I just go with a 3" ATP Ultimate wastegate and 3" all the way? Is there any downside with 3"? I assume I will need to port the hotside more so I don't overboost.
I was going to go with mild steel and attempt to MIG weld it all together myself. Exhaust exit before the passenger rear tire. I had a summit racing turbo muffler, but I blew it out in two races.
