Hey is anyone running MAC's pro chamber exhaust on their cars? And if anyone is does it make a difference in power that you can feel? I was hearing they guarantee 22hp to the ground with it..?? Plus it makes tha car sound even meaner.
Its a very nice piece im using it right now. Makes my SLP's sound a lil more unique since we have 3 other 94-95's around here running the same cat-back as mine. I was gonna go with one when i get my lt's but thanks to loudtoy958 i got a great deal on a new Dr. Gas X-pipe and there is no way im ever gonn part with that thing.
The prochamber is awesome! I wasn't too impressed with my flows until I switched to this mid-pipe. 22 HP? No. Maybe 5-10, but it's the sound that made me choose this pipe. With your setup, I would imagine you are losing some low end torque because of your lack of backpressure from the 3" exhaust, so you may feel a change by switching down low.
