After porting, has anyone used a slightly larger diameter exhaust pipe? I can't use an expansion chamber and still keep the same specific appearance that I'm going for. So I'm trying to go for as unobstructed a flow as possible.
Is this a good idea?...or is untuned back pressure a good thing?
On the bottom of your muffler there is a screw....Unscrew it and pull the inside of the muffler out,take a hacksaw and cut a number of inches off of it and put it back in the muffler and see if that helps to give you more flow....It will make it a little louder,but will help the flow....
