Steel pack mufflers = loud with good tone, if you can find them. I think Brockman is out of business. Their web site is gone.

Straight pipes = very loud with pretty good tone and rap.

I have been running Douglass Steel Packs from the 50's for about 25 years on my truck. They are real burned out and sound better than anything I've ever heard! eek I love em!
