Hey guys,
Hope I don't get flames for this one,
Is a cat really needed?? I have a gtt and on it I have the regu 06 Kakimoto catback with a 3" split dump/front pipe. With the stock cat.
What gains will I see from getting say the catco 3inch high flow cat?? Someone told be it's good to have back pressure, but you guys seem to live by having the best flow possible.
Plus will the catco be legal emission wise???
