I am thinking of doing the TSP y-pipe and Pacesetter headers on my Firehawk. I would like to go with the catted y to keep it "stealth", but am concerned about the cats being a restriction. Is there much power difference between the two?

I believe they use pretty decent cats that don't restrict much flow at all. What catback are you going to be running? If it's one that will gain tons of rasp, then it's better off to go with the catted Y.

If you're going to be using the stock Dual/Dual, go with the ORY. The Dual/Dual sounds just about right with it.

Nah its only a few hp, so its up to you really - especially if you want some stealth.

get cats and an electric cutout, so you have your stealth and you can still scream like no other when you want to
