what is the best aftermarket exhaust for my 2007 crf250r

Recommended Posts

i am just wondering what dual aftermarket pipes will perform the best on my 07 crf 250r. I was thinking about going with the dual fmf factory 4.1 SL (slip-on) with the mega bomb header. what do you think i should do?

Thanks

Darcy

k, im pretty sure you will end up getting an mrd lol. you can get dave to make you a twin setup but he doesnt like making them and they dont preform as well as a single. my suggestion is get an mrd single. anyways, welcome to thumpertalk!

Dave is the owner of MRD, and he makes the exhaust systems. There is a difference between single and dual, single makes more power and is cheaper. I have a Factory 4.1 Titanium Single w/ MegaBomb header and my brother has the MRD Pro Comp and I like the MRD better than my FMF. Plus MRD's are hand built and come with a lifetime warranty! And also are built to your power spec, bottom end, top end ect.

THUNDER-ALLEY makes one hell of a pipe for around 400 or so depending on what you want.

For $1200 I could get a full engine kit with high comp piston, porting, cam, and valves that would put me over 40 HP. Or spend about $1200 on a pipe and get maybe 2hp.
