Collector Size

For 550 hp, I would prefer a 2" tube..... with a 3 1/2 collector.

Had 1 3/4" TTI headers on the car, than swapped to 2" Hooker fenderwell and didn't notice a difference. Thinking the 1 7/8" would maybe be better plus give me more tire clearance as I plan on making my own fenderwell headers.
