Muffler Re-Pack Kit

 Stainless steel rivets included.

Dual exhaust sytems require two Muffler Re-Pack Kits

 This muffler re-pack kit can be used with all Barkers exhausts except the following:

• Yamaha Grizzly 700 Dual Inframe Exhaust - 7AYE-GRIZ700-DLINFR
• Yamaha Raptor 250 Inframe Exhaust - 7AYE-250R-INFR-11
• Polaris RZR 800 Dual Exhaust - 7APE-800RZR-08

 Most modern engines and especially those with EFI, produce exhaust gas temperatures that exceed the temperature limits of traditional packing. Once a fiber's temperature limit has been passed, it becomes brittle and breaks down into particles small enough to be "blown out" of the muffler. Spec 30 is different because it maintains it's strength in temperatures up to 1400F.

Whether you're maintaining the muffler on a motocross bike, an ATV or a utility vehicle, Spec 30 will last longer than the competition. There are many benefits to keeping a muffler completely packed and flowing as it was designed to.  Among them are:

• Throttle response remains crisp.
• Power output is maximized.
• Fuel efficiency is maximized.
• Noise reduction and exhaust tone are maintained.
• Vibration absorption and baffle support.
