There hasn't been much forum talk on this subj lately, so I'd like to start it again. I'm thinkin of simply replacing my stock muffler with this one, and would like any feedback from anybody else who's done the same. I'm particularly interested to hear about how many degress EGT was lowered (if any) while towing, and was there any drone while towing at approx 2000 rpm as well. Any comments/suggestions will be greatly appreciated!
