went to dyno with a friend, he only has CBE(with y pipe) changed, other than that his car is all stock. The problem is the hp gain was not even close to what manufacturer claims. That made me wonder those manufacturers claims 18whp or 20whp gains on exhaust are even true(without tuning)? Not trying to make any company looks bad, just wondering cause I am in the market for exhaust myself, thanks.
