Chris C.
Rating: 5/5
Sounds great, solid build
Needed a fix for my rig and this did the trick. Sound is deep without being obnoxious. Bolt-on install, no tuning needed. No complaints so far.

Been running the quiet core for straightline performance aluminum exhausts on my quad for a few weeks now. Noticeable pull up top after installing. Bolt-on install, no tuning needed. Worth the money.

Ordered the quiet core for straightline performance aluminum exhausts last month and finally got it installed. Sound is deep without being obnoxious. Works well overall, just took a bit longer to install than I expected.
