hey there all i have my friends at BBI AUTOSPORT ( www.bbiautosport.com) doing some r&d work with my car and building a few different exhaust systems on my car to see what kind of power can be made. we finishedthe first one today and the car had an avg gain around 9hp overall with an 18hp peak gain. they had it dynod at autowave in hb.

the first system runs 3 inch right off the header, to a 45 degree into a 3.5 inch back to 3 inch out split to the mufflers. these mufflers are a 52% muffler deally and the next will be 40%

the second system will run 3 inch with an x-pipe placed close at first and then moved more towards the rear and back out to 3 inch to see what can make most power once again.
the first one weighs about half as stock and ful tig welded, it looks real neat.

here are a few pics.








here are the tips we did to run for a week or 2, 3.5 inch hand brushed for a different look.

It seems as if the exhaust tips are to short.....shouldnt they stick out a bit more???
