Two Brothers Slip on KTM 890

2Brothers has yet to let me down. Great Slip on set up, deepens the sound without making it obnoxious. Easy install, took about an hour with wrapping the mid pipe. I recommend wrapping the mid, it is much hotter than stock without the wrap. Thanks Bill! -Jon

VANCE & HINES Hi-Output Slip-On Muffler 48427

Nice looking muffler

Not difficult to install. Most likely will require to replace the muffler gasket. Matches well the look of the bike. Sounds well at low to mid range, a little noisy at high RPM.

Great sound with mild performance increase. Quality design. Price was fair. Bolted on with no issues.

Do not Like the new sticker logo instead of the traditional FMF stamping.

Awesome seller and great communicator

This is my second exhaust from bill in 6 months for two different bikes he had exceptional customer service and always staying on top of time frame and his prices are better then anyone out there . Overall what makes Bill stand above the rest is his customer service and his passion for bikes that itself tells you what kind of person he is and his enthusiasm for motorcycles.

DYNOJET Power Commander-6 - Honda PC6-16005

Solid imporvement to a poor running bike

Had some fuelling issues in the midrange - tough to find ECUs for bikes of this age these days. Power commander sorted it out, very happy with my purchase and Bill's service.

Bill is a solid guy - will definitely shop here in the future

Had a bit of a miscommunication with the shipping timelines offered on the website as the part had to leave the vendor, arrive at Bill's shop and then be shipped to me. I reached out to Bill and he was quick to do what he could to make it right. My part arrived as quickly as he could make it happen and I appreciated the effort he put in. I'll definitely be shopping here again, fair prices and a good guy to work with.
