I'm ginna be getting a pair of bbk shorty headers to add to the rest of my mac h pipe and mac exhaust on my 94 gt. How is this gonna be? Should I loose power or gain a few? The main question I have is am I going to need a tune after I install the headers? And how do I get a tune, at a mechanic or can I buy one? Sorry I'm new to this tuning crap lol. Also how is the install is it a pain in the ass?
