We designed the 919T to use the stock (looking) mufflers. The left muffler has been "re-baffled" to provide no back-pressure which lets the turbo breathe and spool up quickly. So, if you buy one of our systems and you already have the new exhaust and tuner, you really won't need them anymore. You can just sell them to someone else and get some of your money back, if you want.

The modified 919 muffler gives the 919T an exhaust note that is just incredible. If you heard it, you would buy the system just for the sound! It makes a hollow rumbling sound at idle, and throughout the rev range all sorts of different great sounds and ends up at 9500 rpm with a very business-like shrieking sound.

However, there are some folks out there that have spent good money on their new mufflers and really want like to keep them. So, we will be working with our customers to develop different turbo out-pipes to match the popular aftermarket muffler configurations. Jardine makes a nice dual slip-on setup and Two Brothers makes a nice setup also.

One of our first customers, J.G., really wanted to use his Jardine mufflers on the bike, so we built this pipe as a prototype for him, and made jigs so we could reproduce it. We were concerned that the exhaust sound would go straight out the left muffler, so we built a "sound diverter" in the "Y" section, and now both sides sound equal. The Jardines sound very mellow on there, and flow plenty of air. It's a lot more work to make the dual exhaust pipe (notice how it dips down to get around the rectifier, we have a short piece of heat wrap for that) and it's more expensive to coat it, so this will be an extra-cost option. J.G. wanted matte black/aluminum so the pipe is not noticeable, so we made it like that for him. There's also a black heat shield on the front portion of the pipe. We'll add pictures later of the duals on the bike.
