If I put on Cattman stainless steel Y-pipes, a random technology high flow cat, a remus cat-back exhaust,a CAI, a lightened flywheel, an Unorthodox pulley, and an ecu upgrade/replacement how much Hp do you think i will gain from my stock 160. 1991 Maxima SE Thanks

 

You will gain as much power as a few runs on a dynojet will show. Nothing more and nothing less, that is assuming you did baseline dyno before hand. Here is how you find the nearest dynojet center http://www.dynojet.com/lauto.shtml.

 

MY GOD!!!!!!!!!!!!!! how did you ever figure that out????

 

I got it from a magazine while on the "royal throne" . You'd be surprised what you think of while on it .
