3.5" Family of mufflers for HD

3.50” HP-PLUS®  TOURING MUFFLERS for 1995-2010 HARLEY-DAVIDSON FLT, FLHT, FLHX, FLTR AND FLHR models






High performance 3.50 inch diameter, slip-on, touring absorptive mufflers. Fit Harleys equipped with OEM crossover or after market “True Duals” systems. Increased horsepower and torque with our distinctive deep, throaty, but quieter, sound. All new HP-Plus® patented dual chamber absorptive baffle. The large, short front absorptive chamber mutes de-acceleration popping. The long, rear absorptive chamber features our HP-Plus® resonator. Both chambers are wrapped with a laminated muffler packing consisting of a thin layer of stainless steel under a ultra high temperature basalt wool. The stainless steel packing insures long life for the high frequency absorptive basalt wool. The dual layer packing covers the complete length of the baffle to minimize body discoloration and to absorb the annoying higher frequencies. Low speed torque is improved over our 3.00 inch versions. Overall decibel level is reduced while still retaining the high quality, deep, Khrome Werks signature sound. Utilizes factory mounting hardware and clamps. Sold in pairs. Made in USA. US patent 5,173,576. These KW mufflers exceed 50 state sound levels.

 3" HP-PLUS and Touring Lite Mufflers
HP-PLUS® TOURING LITE Slip-On MUFFLERS
Fits 95-10 FLT, FLHT, FLHX, FLTR, and ROAD KING®

Our 3” Touring Lite line of mufflers has been completely redesigned, retaining the great performance and quality sound. The new features are: 16 ga. one-piece shells, upgraded baffle design, bolt and nut baffle installation, and upgraded acoustical wrap materials. The one-piece shell eliminates the possibility of leaks and transition screws loosening or stripping. The baffle is now a similar construction to our 3” stagger dual and 3.5” touring mufflers which is installed with ¼”-20 bolts and nuts – an improvement over the #10 screws. Originally fiberglass wrapped, our redesigned baffle is machined wrapped with a laminated muffler packing consisting of a thin layer of stainless steel under high temperature basalt wool. The stainless steel packing insures long life for the high frequency absorptive basalt wool. This dual layer packing covers the complete length of the baffle, minimizing muffler body discoloration and absorbing the annoying higher frequencies. Fit Harleys equipped with OEM crossover or aftermarket “True Duals” systems. Utilize factory mounting hardware and clamps. Now sold in pairs. U.S. Patent 5,173,576. Made in U.S.A.   These KW mufflers exceed 50 state sound levels.   Touring Lite HP-Plus® Mufflers for 1995-2010 FLHT, FLHR, FLTR and FLHX
