I've perusing ebay religiously for new items for my R300 and came across a coffman shorty exhaust for the 500 that would probably fit.
anyone have any experience w/ this brand? for $200 it seems like a much cheaper option than the twobros.

Coffman Shorty Exhaust: Honda Rebel 500 (20017) | eBay
Wow this actually looks pretty sharp, I like it allot. We need some feedback on this shorty. Youtube doesn't do it justice, but think there might be something on the other rebel (general all rebel) forum. $325 CAD but still cheaper than two bro's. lol.

I am anxious for the exhaust systems to be tested by and commented on by our forum members before I purchase any of the aftermarket items that I would like to have.

Really not the best comparison at all but I found this video of a Kawi Ninja 300 stock vs Coffman shorty exhaust. It may help....?

I did some digging and several people w/ a cb300f tried the coffman shorty exhaust.
turns out they lost plenty of mid range power, which the R300 at this point really can't afford to spare :-(

I'm trying so hard to avoid the twobros though lol. It's looking like the $480 for research and development might be worth the cost after all.

Are you (people in genereal) sure that twobros exhaust wont make you lose power as well?

Good point, nope not sure at all. My understanding was Twobros actually takes time to develop systems/slip ons that aid in performance. But I could just be a victim of good advertising on their part.

The Coffman is really not an exhaust. It is a hollow metal pipe. And it isn't actually made for the rebel, it has an adapter that will allow it to clamp down.

found that out myself, you go to their actual webpage, they don't even have a listing for a rebel, nor any adaptors. and their website doesn't even have the part number that is on amazon. I can only assume however is actually selling it, bought from Coffman a bunch, added a clamp/adaptor themselves, made their part number, now selling it.

image of that bike is dope. love it with the fairings, and so want them. looks good around the motor, headlight, and the piece behind the seat is cool too. Definitely gives it a different look.
Thank you so much for that link!

Cheers

Sooner or later, these parts will be available in the U.S. Hopefully, sooner than later. Right now I like the stock look and enjoy the ride this old guy gets.

Sweet! Let us know how it turns out. Where are you located that you're ordering from? I tried to order from their website, but the language changed and couldn't understand what was what.



As parts are being released third party sellers are popping up on Ebay (from thailand). It'll take some time, but hopefully it's available in the US sooner than later.

There are so many parts I want to order on ebay right now. But the price are obscene. I understand they are just people buying and reselling but the parts are all double the actual Honda price. I understand they are doing free shipping from Thailand. But for a $45.00 part they are charging 90 and for a 110 dollar part they are charging $239.
Sadly I feel my lack of patience is going to haunt me and I am going to end up ordering some of it.
Considering I already got the handle bar risers it is only a matter of time until I want more.

Like any vehicle, they require back pressure. So by removing the stock muffler for a shorty or straight pipe, you'll loss more power then gain. Now, digging some more of my own, it is possible to take an exhaust from the cbr300, which my understanding, has a tiny cat in the downpipe, and put it on a cmx300, then straight pipe for muffler or shorty. The small cat will provide the back pressure, and you get a cool sounding rebel.


I don't have the means, but be interesting if someone tried it out to see if its possible. I haven't seen a cbr completely up close because of all the plastic to verify if this is true, but a friend has an R6, and it has a tiny cat and a shorty, and it sounds amazing. lol.

Your still leaving YOUR cat in when replacing just the muffler so why go through all that with the CBR?

I'm from austria. Yeah everything is a little strange on their site. But i sent them a mail and got a reply within one day. Only bad thing i have to pay 10.000THB for shipping. Thats about 200€.

But its still cheaper than everything else i get on ebay or stores.

Ofc i ll keep u updated. I ll recieve the goods in 10-20 days.

Cheers
