2010 H-D FLH and Sportster Exhaust Options

The new 2010 Harley-Davidson FLH model bikes have just been released and SuperTrapp already offers ten exhaust slip-on options to fit them:
 
1 SE Series '10
                          P/N 128-65117              
2 Kerker Slip-Ons '10

6 Internal Disc Series w/ Fishtail End Cap
          P/N  628-78054             
7 Internal Disc Series w/ Tapered End Cap
        P/N  628-78055             
8.Megaphone Series Chrome Megaphone 
         P/N  728-78053             
9.Megaphone Series w/ Chrome SlashMegaphoneP/N728-78054             
10. Kerker Slip-Ons with Mikuni Core
                     P/N 128-78045

There is a brand new version of the SE specifically designed for the 2010 models.  It has all of the great features of the SE series but has been redesigned to produce that signature SE sound on the new bikes.  SE Series have been used by one of the world's largest OEM's for years.  They're the champion of numerous magazine shootouts with a 10 - 12% horsepower gain.  SE's are the king of bottom-mid range torque with a steady, tough, low rumble and are only 3dB louder than stock. 
 
A new Kerker Slip-On has also been developed specifically for the 2010 models.  Although the majority of slip-ons in the market today will fit the new bikes, their sound quality does not meet customer expectations.  The 2010 stock head pipes were redesigned by the factory and we developed these new Kerker slip-ons to produce that signature Kerker sound in conjunction with these new factory head pipes.   Kerker Slip-Ons have a proven 12 - 13% horsepower gains with great mid-high range power.  Kerker Slip-Ons are 8dB louder than stock with a profound, deep, throaty rumble. 
 
SE Series and Kerker Slip-Ons are compatible with 14 end caps, including the brand new, Yaffe-designed Holy Moly end caps, to allow riders the ultimate in personalization. 

Riders will be thrilled to know that SuperTrapp's newly-released FatShots Slip-Ons will also fit the 2010 models.  These new 3.5" diameter, fully chrome plated muffler bodies flare out to a 4", slash cut end with a straight through 2" diameter, pillow-pack wrapped performance core that is capped off with the legendary SuperTrapp 4" discs and polished trim ring.

By adjusting the number of discs, these new FatShots Slip-Ons have the ability to be the quietest performance muffler out there with a richer stock level sound, but enhanced performance. It performs better than stock in a sound compliant configuration.  FatShots Slip-Ons are neighborhood and stereo-friendly and pass the new SAE J2825 sound test.

These Slip-Ons truly demonstrate the performance and customization that a tunable exhaust has to offer. Adding 4" discs will increase the horsepower, exhaust tone and flow. Subtracting 4" discs will reduce the sound and increase low-end torque.

FatShots Slip-Ons come complete with twenty-four 4" discs and all of the necessary hardware and mounting instructions, so you can get back on the road in no time.

FatShots Slip-Ons are compatible with SuperTrapp True Duals for Harley-Davidson '09 Baggers (P/N 168-71578, MSRP $429.00) as well as SuperTrapp True Duals for '08 Baggers and earlier models going all the way back to '85 (P/N 138-71574, MSRP $399.00).

SAE J2825 Sound Test And What It Means To You


The Society of Automotive Engineers (SAE) International has produced a simple, consistent and economical sound test standard that can be used to determine whether a streetbike (on-highway motorcycle) exhaust system emits excessive sound, the American Motorcyclist Association (AMA) reports.

The J2825 "Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles," issued by the SAE in May, establishes instrumentation, test site, test conditions, procedures, measurements and
sound level limits. According to the SAE, the J2825 standard is based on a comprehensive study of a wide variety of on-highway motorcycles.
 
"The motorcycling community and law enforcement have long sought a practical field test for measuring street motorcycle exhaust sound," said Ed Moreland, AMA vice president for government relations. "Thanks to the hard work of the Motorcycle Industry Council, and the SAE engineers involved in
the project, for the first time a simple field test is now available.

"The AMA maintains that few factors contribute more to misunderstanding and prejudice against street riders than excessively noisy motorcycles," Moreland continued. "With the new SAE J2825 standard, street motorcyclists can now determine how quiet, or loud, their bikes really are."

Moreland added that the new standard follows a template established years ago with the SAE J1287 off-highway motorcycle sound test, a standard recommended by the AMA wherever off-highway motorcycles are operated.

The SAE J2825 on-highway motorcycle sound test procedure is similar to the one used for the SAE J1287 off-highway motorcycle test. The streetbike measurement requires holding a calibrated sound meter at a 45-degree angle 20 inches from the exhaust pipe of a running engine. The procedure spells out how to do the test with the bike at idle, at a predetermined engine speed ("Set RPM Test"), or by slowly increasing the engine speed of
the bike, known as the "Swept RPM Test."
 
The SAE J2825 standard, prepared by the SAE Motorcycle Technical Steering Committee, recommends a decibel limit of 92 dBA at idle for all machines or -- using the Set RPM or Swept RPM Test -- 100 dBA for three- or four-cylinder machines, and 96 dBA for bikes with fewer than three or more than four cylinders.
 
"The J2825 test allows jurisdictions around the nation, struggling with complaints about excessive motorcycle sound, to set reasonable limits in accordance with the SAE standard," said Moreland.


SuperTrapp is your performance and sound test compliant solutions provider!  Our legendary, patented, tunable disc technology has allowed
us to have a leg up on the most recent sound compliant tests.  The following products pass the SAE J2825 sound test.  (Tests were conducted on a 2007 FLHRC).

SuperTrapp WaveTech Exhausts Available for Sport Compact Imports


WaveTech exhausts 
Auto Catalog Cover 2009
(MSRP starts at $125.00) are designed for four and six cylinder sport compact imports.  They're available in both an 8" length and a 14" length.  Both lengths are available in a 2.25" or 2.50" inlet diameter.

The polished T-304 stainless steel body comes with a polished stainless steel closed end cap.  Optional end caps are also available in four color options, including polished aluminum TrappCap end caps.

SuperTrapp's WaveTech exhausts are equipped with a perforated, stainless steel core.

These exhausts are completely tunable.  The removal of 4" discs decreases the exhaust opening and increases back pressure.  This decreases the power band to create more low-end torque.  It also decreases exhaust tone and enriches carburation.  By going the other way and adding 4" discs, the exhaust outlet increases and back pressure decreases, widening the power band at the top end.  It also increases exhaust tone and leans out carburation.

Dealer Exhaust Display Program

We have an exciting offer for dealers
Dealer Display
effective immediately!  We recently launched
a "Dealer Exhaust Display Program" to help
increase dealership sales.
 
SuperTrapp will give dealers a 30% discount
off of their already discounted dealer
pricing on all SuperTrapp exhausts and
accompanying end caps used for display. 
 
What does that mean for dealers?   It means having the most cutting edge designs and performance enhancing exhausts displayed on
dealers' showroom floor bikes or on the exhaust wall behind the Parts Counter. After all, customers are visual.  They want to know what the pipes will look and sound like on their bike.  Now dealers can show them and boost their sales while doing so.
 
All we ask in return is that dealers take a high resolution picture or two and e-mail them to SuperTrapp at
Marketing@SuperTrapp.com with a brief testimonial of which exhaust was ordered, what the customer feedback was and how displaying SuperTrapp exhausts helped increase dealership sales.  We will then plug your dealership on our website,  Pipeline and you could possibly end up in our 2010 catalog. 
 
We encourage dealers to order their exhaust, get it on the bike, take some pictures and watch the sales roll in!

And don't forget to let us know when you're hosting an Open House, or any event.  We'll send you a Rally Pack filled with banners, catalogs, decals and SuperTrapp swag to raffle off.
 
Don't wait!  Contact us at
Marketing@SuperTrapp.com or 216-265-8400 to place your order today!
