Great Exhaust

I've got a 2019 Honda CRF230. Great exhaust, really opens the bike up and sounds amazing. The bike starts better as well and the exhaust just looks great on it.

Extraordinary performance!!

I bought this a month ago and this exhaust not only sounds great but looks amazing and makes your bike look very professional and aggressive. I am very satisfied that I bought this as it makes my bike look like a racing bike.

Excellent performance, Awesome sound!

Have had the pipe on my bike for a couple days, easy to install, fit was perfect, heat shield lineup was perfect. I did modify the plastic around exhaust to give more exposure for admiring this awesome peace of machinery. The performance is noticeably better, after opening up air box and going up one jet size, bike was missing something, “THIS PIPE”, now responds, I am able to get my 2014 KLX140L to 62 mph, on street, It is street legal with duel sport tires. WOW, don’t hesitate to make the purchase. Ordered it on Thursday, was in my grubby little paws on Monday, Happy Happy Happy!

I love how its fully rebuildable

I bought this about two months ago with a few other bolt ons. This is the first thing I bolted up but havent had time to finish with everything else like the jetted carb, etc. So Im excited to hear it run in the near future.

A: The bore size has nothing to do with whether or not the exhaust will mount up on your bike. :) As long as there is an exhaust for your fitment it will fit.
