i did single instead of dual Joe i have two friends that have muffler shops and they have taken classes on LS exhaust building. 2.5" single is supposed to be good up to about 450 hp. and i am at 450hp right on the nose. they said the different pipe configurations like x and strait across mainly change sound. the classes they took showed very tiny differences in HP and torque and when the curve peaks. they said they have heard hundreds of opinions but based on the dyno which does not have opinions you can get the same results with most any config as long as you go with the 2.5 diameter pipe. i used the Dirty dingo engine mounts and a strong home made trans mount so there is almost no engine movement so no need for any type of flex pipe. i did not use cats i put my O2s about 12" downstream from collectors. i made my own hangers. sounds very much like a stock everyday car until you jump on it which makes it even more of a sleeper.
