I went to a muffler shop over the weekend to get a stainless tip put on my exhaust. To make a long story short I ended up getting a flowmaster 80 series installed with a stainless tip all for $250. Its not to loud on the inside but when you get on it it sounds good and I was very surprised with the performance.

I have never seen a muffler gain more that about 5 - 8 hp, you really can not feel under 10 hp gains, your a$$ must be good. ;)
