Grand Prix 2:1 for Softails
Firebrand has been in the exhaust game for well over a decade , " but the last few years they ' ve really stepped up their game , and the new Grand Prix two into one is a solid example of that work ." Using a shorty version of its bulge end Grand Prix muffler , Firebrand has mated it to a stepped collector and a high flow stainless header . Firebrand ' s Director of Marketing , Jon Montgomery , says : " The end result is a
quality system that looks the business on modern Softails . We integrated a perforated baffle and a durable packing material into the Grand Prix 2:1 for a commanding exhaust note without the ' pitchiness ' that can come with a short system . Naturally , we made sure there was a noticeable bump in power as well ." The Grand Prix two into one is available in brushed stainless as well as its durable black coating and fits most narrow wheel M-8 powered Softails from 2018 to 2023 - clearing bags and passenger pegs . It is also available as a 49-state or race-only version . Firebrand is distributed exclusively through WPS / HardDrive .

Baker Direct Drive 7-Speed
The Baker Direct Drive 7-speed ( DD7 ) was engineered to make full use of the torque and power output of the Twin Cam and M-8 motors via precise gear ratio management , delivering " smooth , crisp shifting , continuously pulling acceleration and strong take-offs from stoplights ." The DD7 upgrades any existing 2006-later Big Twin 6-speed to a full 7-speed transmission . Bert Baker says that " the Baker DD7 is more than just another gear added to the mix for the sake of one-upmanship . That 7th gear enables the motorcycle to now make full use , by way of gear ratio management , of the torque and power put out by the new 96 ci and 110 ci motors rolling off the assembly line in Milwaukee . We did not make this transmission a deep overdrive , rather we shortened 1st gear and tightened up the gears to deliver the riding experience that riders were after when they bought their bike . " The gear ratios leave the rider with the experience of smooth , crisp , continuously pulling acceleration from 1st all the way through 4th gear . Then you are able to start getting into the cruising portion of the program in gears 5-7 . No big drops in rpm from one gear to the next or lugging the motorcycle off of a stop light , just smooth , uninhibited acceleration . " We did not stop at just fixing the gear ratios . We improved the smoothness and crispness of the shifting by reducing the main shaft mass by only having 1st gear be a part of the shaft , rather than 1st-4th gears like on the stock unit . " Reduction in rotating mass for shift quality is a fact that has been utilized in the automotive world for years . We ditched the stock detent arm and spring assembly from the door in favor of a linear detent that decreased friction while increasing smoothness when coupled with the all-new shift drum design . " We have tightened up the dog teeth on the gears to prevent the loud clacking noise that accompanies every shift on the factory 6-speed . Through the use of a billet bearing door , 28 % wider bearings in the door , steel bearing retainer plates and full width gears , the durability and strength of our unit is a drastic improvement over stock . By utilizing fully diamond ground , helical gears in 1st and 4th-7th , we are able to deliver a much quieter riding experience . 2nd and 3rd gears are diamond ground , with spur gears to handle the peak torque that is reached in that range ." The DD7 includes a Baker shifter pawl , new main drive gear bearing and seal , door , top and side cover gaskets and is compatible will all types of aftermarket hydraulic side covers , as well as the stock Screamin ' Eagle versions . This is a direct slide-in installation with no case modifications needed , that clears all exhausts and
works with all aftermarket clutches . Backed by a fiveyear limited warranty , it is available for 2007-later Softail , 2007-later Touring FL , FLT , FLH and 2006- later Dyna .
