Got the longtubes...now do I need 3" exhaust?
My longtubes should be here today and the 1 3/4" primaries collect at a 3" collector. Looking for opinions as to whether or not I should go 3" all the way back, only a 3" H/Xpipe, or just stay with the 2 1/2" Hpipe?
whatcha think? what type of thought goes into exhaust size? I had heard that anything over 450HP needs 3", is this true (Cause I'm not making that much......yet) If I just put the longtubes on and reduce them to 2 1/2", will I still get the power gains.
