So as my other posts show, I've been searching for a deeper and throaty exhaust, as I have not been happy with my Screamin Eagle Street Performance Exhaust. So I looked at the CFR's but everyone was out of stock. So I did some research on the Bassani DNTs. I located a you tube video of a 2015 CVO with the Fullsac DX headpipes like I have. Granted a video doesn't really give you 100%, but the surround sound helped. So I put them on today and WOW what a difference. So here I show my ignorance. I looked through the Screamin Eagle Exhaust and I could not see through them. The Bassani, whole different ball game. The bike feels as though it has quite a bit more power and throttle response. I assume because of the amount of exhaust gas its pushing out opposed to the more restrictive Screamin Eagles? Or a placebo effect. I take the bike in on Thursday to have it retuned for the new exhaust. If your on the fence I'd say go for it. Yes at 65 MPH at 2500 rpm yin 6th gear, you can hear the radio just fine.
