Biltwell Mini Mufflers slip fit over the open ends on 1 3/4" O.D. header pipes to change the look and sound of the exhaust system on your motorcycle. A perforated steel baffle tube with fiberglass wrapping inside the mini muffler can be removed to change the exhaust tone. These babies beat drag pipes, and they are super-classy. Small muffler, small price, big sound.

TIG-welded 16-gauge steel canister with 1 3/4” I.D. slip-joint end
TIG-welded, stamped steel hanger bracket with Biltwell anvil marking
Gold zinc plated 16-gauge perforated steel baffle with stamped end cap

Anthony B:They will, but you will need to get a reducer kit (Dime City Cycles sell's them for about $7). These fit 1 3/4" O.D. pipes, Triumph Bonnie's and Thruxton's have 1 1/2" pipe end's. The reducer's (cylindrical metal fitting) just slip's inside the end of the muffler that slip's over the pipe end and it reduces these metric mufflers from fitting a 1 3/4" pipe to a 1 1/2" pipe. To mount them you will just need to purchase Biltwell's Duo Muffler clamps, they're sold as a pair for around $30 on here, Revzilla, or you can purchase them directly from Biltwell's site along with the muffler's, or LowBrow Customs site as well…just in case Rev ever runs out of them.Nov 19, 2014
Anthony B:Also, as I'm sure you know, make sure to remap your Thruxton as well if you decide on these. Should cost anywhere between $40-$60 at your local Triumph dealer. Price is just dependent on how long it takes the employee to remap your EFI. Other than that these would work great!Nov 19, 2014
Anthony B:They will lessen the db's a little bit, not extensively though. If need be and you want those db's up, just take out the removable baffle. If you go to Biltwell's site or LowBrow Custom's site, or youtube you can watch videos on each muffler to hear what it sounds like. Just as the description says, they may be small but they pack a good punch…pretty dang loud!Nov 19, 2014
Anthony B:They will, but you will need to get a reducer kit (Dime City Cycles sell's them for about $7). These fit 1 3/4" O.D. pipes, Triumph Bonnie's and Thruxton's have 1 1/2" pipe end's and so should a Scrambler. The reducer's (cylindrical metal fitting) just slip inside the end of the muffler that slip's over the pipe end and it reduces these metric mufflers from fitting a 1 3/4" pipe to a 1 1/2" pipe.Nov 19, 2014
A shopper asked:Hello, I have mounted these mini mufflers on my Kawasaki W650, the sound is great but too loud. I wonder if it exists a solution to reduce the sound excepted the existing fiberglass tube inside ?
