D3 Exhaust System - XR/CRF80/100

Xr100 big hire and exhaust.

Excellent stuff. Fully recommend.

Fit, looks and sounds great!

Fit perfect! no hassle of trying to make thing work. Sounds great especially paired with the 120 big bore kit.

The best exhaust for xr100r, imho

Fit and finish are excellent! This exhaust performs better than expected and sounds fantastic. It is louder than stock but nothing that is obnoxious. I did also purchase the cancelcore quiet insert, but didn't see a need to use it. I did replace the jets. The pilot is a 38 and the main is a105. I might go to 110 on the main, but for now the bike is running its best ever.
