Well I'm learning get the air in and get the air out! :-) I had already installed a header from many years before but was still using the stock exhaust and muffler. So off to the exhaust shop I went. I don't have any really good pictures of the stock exhaust but it was about 1 3/4" diameter and had some unnecessary bends in it. I went with new 2 1/2" exhaust and a MagnaFlow muffler. I did notice some increase in power and I could finally hear my engine lol.
I tried it without the Cat but it was really really loud, cool at first but got a little old after awhile so I had a high flow Cat put on and that did the trick for me. I didn't notice any difference in power either.
