Herfurth Aluminum Racing Mufflers (HARM) Titanium Core "Drag and Drive" muffler

Herfurth Aluminum Racing Mufflers (HARM) introduces the next generation of lightweight sound control!  The new titanium core provides additional muffling over the performance proven Virus Vent muffler for the guy that is looking for a quieter, more mellow sound without sacrificing weight and horsepower.  3" and 3.5"  mufflers have a 5" case and the 4"  muffler uses a 6" case.  Case length is 11.5" and overall length is about 14.5".  Average muffler weight is approximately 4.5 lbs each.

Also available with 1 or 2 v-band options.  By choosing this option you'll get 1 or 2 v-band flanges welded onto the muffler, with a steel flange for attaching to an existing exhaust system.   These mufflers are built to order so please allow 7-10 business days before shipment. Mufflers are sold each. 

Free shipping to USA!!!

 Because these are built to order, there are no returns on HARM mufflers
