Yeah I agree with starscream88 FRPP did design the motor and probly knows whats best, but I bought a pair of Headman longtubes with a 3'' collector and ive been happy with them except I wish I had bought ceramic ones too. Cause they have turn nasty lookin and i gotta take them off and get them coated of painted.
I have Mac headers on mine, they work well. As for fit wise everything should bolt up the same, the exhuast jigs are usually pretty good. If you are worried about emissions than go with a two cat hpipe. Make the hpipe 2 1/2 inch, it will give a nice deep sound. Hopefully the back half of the exhaust is 2 1/4, bigger is not always better. After the gases travel throught the mufflers they lose there volocity, a smaller tail pipe helps keep up the exhausts volocity. With cars that are not overly modified, larger exhaust can make them slower.Also stick with an hpipe, don't go to an x. An h will give more torque which you want on the street, and x's are more better suited for higher rpm cars. As for brand of Hpipe, take your pick they all are pretty good. good luck
I got BBK headers on mine. Love them, if u get shorty headers they will bolt up to stock h-pipe fine. long tubes are another story. stick with shorty equal lengths anyway on ur stock setup. if u go with bbk get the matching bbk x-pipe later on when your ready. and as for header gaskets, get fel-pro copper wire gaskets and save yourself the hassle of having to change the gaskets again in a year!

You obviously know absolutely nothing about science...cooler air is more dense!!! Why do you think we always want our engines sucking in cooler air??
From personal experience I say stay away from MAC exhaust...especially the LT's. Mine will be coming off once I have the spair change.
go into the reviews area above and read away.. there is more info than you need in there....
