Dale's FJR 1300 slip-ons really enhance the beauty of the bike, wake up the performance and offer a nice smooth exhaust note. We like to think they are works of art not just another set of slip-ons. The high flow street core Holeshot mufflers are hand assembled in-house and constructed from high grade polished 304 stainless and 6061-T6 aircraft aluminum. The FJR Holeshot slip-ons weight about half of what the stock mufflers do. They are available in fully polished or our powder satin black canisters with polished stainless front and back end caps. The tips are hand tig welded to the end caps in our Jig fixture using a foot controlled rotator which allows us to use no welding rod for a super small precision bead. We also designed a very clean stainless laser cut center stand stop tab that gets full contact of the rubber bumper when the stand is retracted. Dales polished elbow pipes are also separate from the mufflers so during your installation they can be slightly rotated to get the mufflers and tips adjusted to one another perfectly to the same height. To complete the package for our customers we include a new set of original Yamaha header pipe gaskets so you don't have to hassle with it.
These are just some of the little details and consideration, Dale thinks of when designing a new set of Holeshot exhausts.
On our in-house Dynojet dyno our totally stock FJR test bike made 122.4 HP @ 89.0 ft-lbs. With the Holeshot slip-ons added it made 126.4 HP @ 91.1 ft-lbs. The testing was done on a very hot mid 80 degree day.

It was 2 to 4 horsepower ahead all the way up to redline and about 2 to 4 ft-lbs of torque also. This was without any tuning done and the FJR runs pretty smooth without any big flat spots in the power band.
Note ! We now have tested the FJR / TFI tuning box and have several customers running it with our Holeshot slip-ons as well as full header system. It offers smoother running, cooler engine temps, and a bit more power and torque. The TFI tuning box is the easiest way for the home tuner to dial in the proper air fuel mixture, and Dale now has his own settings he can provide you after your purchase of the unit. No dyno time or downloads are needed with this set up. Please click here to view the FJR / TFI tuning box page
Note! High Temp Silicone is required when installing our exhaust systems. See Below.
