with no muffler
after I took off the stock muffler I started it up, at idle it didn't sound much different than it did with a muffler on it, and even revving it up did make much of a diff. I think if I had to do it again I would just remove the stock muffler and get a good muffler shop to make me a pipe to replace the muffler and save a ton of money, been a week now and a few hundred miles, between 2 and 3 grand on the tach it does sound good going down the hiway
