Great sounds without making your ears bleed

The Coffman Thunder Exhaust is an excellent choice for the Rebel 300. The stock exhaust is pretty anemic sounding. I replaced mine first with a Vance and Hines, but the result was ear splittingly loud . The Coffman produces a great sounding burble that is deeper and louder than the stock exhaust without being intrusively loud while riding or starting a range war with the neighbors. With the baffle in I also don't notice a drop in mid-range power like I did with the Vance and Hines. Over all this is a great exhaust for this bike. Highly recommend!

Just installed. Sounds Amazing.

Best exhaust for rebel 300

All other exhausts for rebel 300 are garbage don’t waste your money, buy the Coffman. The rebel 300 has two problems. First it’s a single and just about any exhaust makes it sound like a dirt bike. Second is the catalytic converter is in the muffler so any exhaust is ridiculously loud. Not the Coffman thunder, while it is most defiantly louder than stock. It is not in unbearable, it is not annoying, and it does not drone on horribly. I use my rebel for commuting daily and this exhaust is amazing and I love it.

Best Exhaust for the Rebel 300

Ordered mine from eBay but wish I had ordered here as I would have saved $40 on sales tax since I’m not in California. Anyways, I love this exhaust with the baffle in. Much more controlled compared to the other exhausts out there since the cat is in the muffler unlike the Rebel 500. Performance seems completely normal, people can finally hear me which is very important for safety, and I’ve already received tons of complements on the new look and sound. Thanks Coffmans.
