Fired up the car today with the new exhaust, it sounds pretty roudy. It was very loud before and now it is even more loud, but I am sure the new setup will yield a few hp for me.
Old setup: MAC 1 3/4" x 3" long tubes, MAC 3" prochamber, MAC 3" produmps.
New setup: Kooks stainless (PIMP) 1 7/8" x 3.5" long tubes, 15" extenstion off the collector into a bullet muffler.
Should drop about 20 lbs or so, not to mention the extra room I will have in the rear of the car for suspension work. I had swapped from the N91 to the N112 camshaft but the extra duration was too much so we had to put the N91 back in today which blows. Added also new valve springs. And had Lenny loosen up the converter, should be close to 6000 rpm on the t-brake now... I'll try to post a video clip tomorrow of the exhaust.
10.50s on pump gas or break!
