I prefer a nice sounding set of pipes with good mufflers. So much of Hot Rodding is first impression to the public, just never saw a good reason to offend those who don't like the noise with an obnoxious sounding set of pipes. Sure don't need a cop magnet for a car anyway... Just never have got into the open exhaust on the street. Another thought, Hot Rodding is on a precarious list of "could be an endangerd species" in many areas and I sure don't want to give the Hot Rod haters more ammunition to shoot us down with then they already have.
