These new mufflers are simply awesome! The design is a 3 chamber muffler with a unique internal flow wing that was designed for efficient exhaust flow, but yet without the noticeable interior resonance of other performance mufflers. There is no packing and no restrictions. These mufflers are made entirely of 16 gauge aluminized (or 409 brush finished stainless steel--add "SS" to the end of the part number) steel, and are mig welded robotically. They are not reversible, and are designed to provide increased horsepower/torque, and increased fuel economy, along with a deeper and more aggressive tone. These mufflers are more aggressive in the interior of the vehicle than our HVS mufflers, and flow a few cfm's less than the HVS mufflers.
Note: to purchase these mufflers, you will need to email us at mike@heartthrobexhaust.com or call 320-693-0222 for ordering information.
Note: add "SS" to the end of the 4 digit numerical part number for the brush-finished 409 stainless steel muffler.
