3" exhaust, N/A Edition
#23
Is 3" better for turbo car? Absolutely. Does it make or break a race car? No.
I don't want to sound like an askhole, but in the name of science i will eventually A/B 2.5" and 3" on an n/a car. Both on essentially stock longblock (where i expect 3" to have no improvement at all, and maybe lose torque) and on a Full-Swag-Ahead n/a built motor. I have an RB + Hytech 2.5" setup on the car right now, and i'll have a Maxim Works + 3" setup made. Not perfect science because of the different headers, but general consensus is that the Maxim Works don't perform any better or worse than the RB, so it's close enough to at least let me identify 3-5whp differences i'd imagine.
