Calculated at Checkout

Decibel Killer Muffler Insert reduces the volume by 9 dB. Exhausts with the decibel killer installed still gain on average 5 Hp over the stock exhaust. Installation is as simple as bolting the decibel killer into your Toce Performance muffler, between the canister and the inlet flange.

    No more ear ringing!

    This Db killer actually refines and tones down the insane, obnoxious sound the muffler produces, making the ride more bearable and enjoyable whether on short or long commutes! Extra long bolts are included. Make sure to use a copper exhaust gasket (not included) to fully seal the db killer in and to ensure no exhaust leaks!

    Great sound

    Got the Toce full system for my FZ07 for the appearance and sound. Rode with no DB killer for about a month and a half, and the sound was jsut too much. Decided to get the db killer, and was skeptical that it would make much of a difference. I was very surprised to find that the idle and lower RPM range is now much more reasonable, while the higher rev range is still nice and loud. Highly recommend adding this to your exhaust purchase.
