But I will be showing why I got 3" exhaust soon enough... Heh heh.

Will a crossover pipe help for the person who must have their main pipe split?
Personally I am happy with my set up.

What is your set up?TY. I don't understand how a crossover pipe will exhaust now is single going to the muffler and then duel comeing out. I took a look under the car yesterday and it doesn't look like a 3" cat under there.I tike it is a 2 1/2".I won't know for sure until I take the exhaust off.
