I don't know about durable, since I've only had the Bullets in the '57 since late summer. Buddy who's had 4" versions on his 10-sec MC for 3 years said something recently about believing they're pretty much blown out now.

At idle, it is a little loud. Under power, they crackle something fierce. Full throttle, quieter than open exhaust, at least. But, they didn't cost me any performance vs. open.

Shall we say "nervous" is a good description of my mental state when I'm driving home from the track after midnight.

heres what i need to do, i drove the car down the street, the volume is pretty good i like it, BUT, at WOT there is a lot of bark in the exhaust, id like to cut down on it, does anyone have any suggestions as to what muffler to use to get rid of it?

if you knew it was gonna be so loud, why did you get it in the first place?
