Good bang for your buck

It's great easy installation I didn't notice a power gain but the main reason I bought it was cause I failed sound test (96 db) but It didn't lower the db as much as I had hoped... It went from 97.5 to 94.1 although It was in a white bros aluminum pro not a big gun but super easy to install and the thing I loved the most about it was... I wasn't all itchy after like normal re pack kits

Great product has been repackaged so cleverly and is therefore easy to install
I would recommend it.

Great Product

Highly recommended this packing. Easiest install I have ever done. The packing has an adhesive strip that holds itself tight to the inner barrel of the muffler, making it a sinch to slide the packing back into the muffler housing.

Q: I have husqvarna TE510 with FMF pipe.?

I packed it with loose fibreglass muffler packing & it blew it to end of pipe after one ride. I was thinking it would be better if I was to use a mat rather than loose packing????

A: It's possible that you didn't use enough packing. Explaining that it "blew to the end of pipe" suggests the entire silencer wasn't filled. The mat type packing can be used, but the string/loose packing tends to work better and last longer in a 4-stroke exhaust.
Q: Does it fit a big Gun Evo on a renegade 800xxc 2011?

Q: Will this work on a Motoworks SR4 pipe?

I can't find a Motoworks repack kit anywhere. I was told Motoworks sold all of there exhaust parts and is no longer making them. I also would like a spark arrestor (same pipe), but can't find that either.

A: Unfortunately this packing kit will not work the Motoworks Exhaust. For this application I would recommend a universal package of 4 stroke packing from FMF. We also do not have any of the spark arrestors for this exhaust available. Your best option would be to contact Motoworks directly to see if they would be able to send you one.

A: I wouldn't recommend using this kit for the HMF exhaust. This is prepared to fit the big gun and if you have to cut it down to fit, it may just unravel on you. FMF makes a great product for packing, and very easy to cut down for size.
