I mounted the new exhaust this morning before golf. Observations during mounting:1. Yes the front mount on the header pipe needed to be bent a bit. The chrome flakes off almost immediately when you bend it.2. The short muffler wouldn't clamp down on the header pipe firm enough. Stripped out the small metric bolt (knew it would do that) and replaced it with a larger US bolt that had to be screwed into the clamp holes. Cranked down on that and now the muffler is solid on the pipe.Observation while riding:1. The engine does seem to like this system much better. It breathers easier and spins more freely.2. Acceleration seems better but that could be due to the sound.3. The sound is great. Quiet at idle and low speed take off, but will get real snarly when the throttle is twisted.Overall: I think the system is a good buy. It is better looking, sounding and running - and that's alot of better for $180. For sure a top mod needed by most any Bullet.I am keeping my stock system in case I want to go back to silent running some day.
