Q Baffled by the Super Duke’s exhaust sound
In a recent touring test to the A1 Ring in Austria, Richard Newland spoke about fitting the baffle back into the GT’S Akrapovic “for a less noisy trip”. Is it an Akrapovic slip-on bolted to the original cat, or is it a full Akrapovic system with a decat? Is there much sound difference with or without the baffle? Erik Steen, email
Answered by Richard Newland, MCN Deputy Editor The Akrapovic end can is an official accessory for £729.53. It is just a slip-on, not a full system, and doesn’t decat the pipe. It’s fully road homologated with the baffle in, and yes, there is a noticeable difference with the baffle out. I static measured it with a noise meter blipping the throttle, and it peaked at 99.8db baffle in, 105.9db baffle out. The baffle is very hard to remove and refit, due to it being a really tight distress fit with a bolt to secure it, and having done both I just leave it in place now.
It sounds good enough with the baffle in
