Trying to keep it a sleeper

[shotgun]

The street pro is the most "flowmasterish" sound, it is a 2 chamber with nothing to blow out.

No need to go back to the EGR , it helps at cruise with a little better MPG.

Thanks for all the info guys!

Thought I was ending the thread but I just thought of an important question for a rookie like myself...

Should I try to duplicate the path of the stock pipes, humps and all? Manifolds collect under the passenger seat and the single tube runs diagonal the entire length of the car over to the driver's side, after the axle it bends back to run parrallel with the axle and dumpout the passanger side with the muffler behind the axle.
