Best purchase for exhaust

Exhaust fits perfectly on the bike, makes coldstart a lot easier, give the power a little more of a "kick" to the bike, and give it a beefier sound.

Well worth the money

i put this exhaust on my 2010 honda 250f. the bike was kinda slow stock but ive never noticed such a power gain from just an exhaust as much as i did with this one. it also sounds great. it sounded like the bike had motor work from just the exhaust. i have a full race motor in it now and this is the best exhaust ive ever ran on any of my bikes! GET ONE!!!!!

AMAZING

For the 09-10 CRF450R this exhaust is amazing! Massive power increases throughout the ENTIRE powerband.I actually have a Pro Circuit T-4R on my CRF450R, which takes away a little bottom and adds a ton of top end (which I prefer for my riding style). I had the opportunty to try/test the Yoshimura exhaust and it adds power everywhere! It's also premium quality and style, as is the Pro Circuit.

A: No. The 2010 Honda CRF250R exhaust would be different than the 2011 CRF450R exhaust.

A: No. Yoshimura list pipes for the CRF450R for models 2009-2010, and different part numbers for 2011-2012. The only other exhaust offered from Yoshimura is the RS-4D for your 2011 CRF450R.

Q: Resonance chamber
Over 4 years ago
I've seen some of the pros bikes having resonance chambers on the header. Can I get that? Or is that a custom thing?

A: Yes, companies like FMF and Pro Circuit offer exhaust systems with a resonance chamber. The Yoshimura RS-4 will not have a resonance chamber. I would recommend taking a look at the Pro Circuit Ti-6 system or the FMF Factory 4.1 exhaust system.

Q: Will the muffler fit the stock header

A: This is actually a full exhaust system, it would include the Yoshimura Header pipe. The muffler will only work with the Yoshimura Header, it will not fit the stock header.
