If I were to put a cold air intake in with a K&N, remove all the A.I.R. stuff and the smog pump from my 88 L98 GTA , and replace the manifolds with shorty headers from Flowtech, Y Pipe, straight pipe the cat, and put a Flowmaster Muffler instead of my Turbo Muffler, how much of an increase would I feel in the enigne's power? Thanks...AARON
