Vandemon Titanium Low Mount Exhaust System ZX4R-ZX4RR 2023- 2026 KAWAZX4RTILMEXHA VA-76

ZX-4RR Vandemon low mount exhaust

Full titanium, quality welds and perfect fitment. No instructions but easy install and sounds phenomenal: bike screams. Shipping was fast from Australia. First Vandemon exhaust but would totally get one for another bike.

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.

2024 KX 450

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.
