'11 CRF450R...Aftermarket Exhaust

Recommended Posts

I'm shopping around for an aftermarket exhaust (full system not slip on) for the new bike. Looking for opinions on performance gains. What did you install and how did it affect the power? Better up top, or more bottom end, or better all the way through? Weight is another concern, and I will probably go titanium. I don't want to go carbon fiber due to durability issues.

Akropovic. You won't find a better-made product. It's also the lightest made.

Alum/Stainless Yoshimura RS-4.... love it and was only $440 for the full system. Wish I had the money for the full titanium setup but oh well

I was torn between the Yosh and the Akrapovic, but didn't want to spend $$$ on an exhaust.

MRD! Nuff said.

Ummm...not enough said. What does it do to the power?

Thats just it. Call him and tell him what you want it to do. Thats what he'll build you. And it comes with a warranty too. If you bend the thing all up, he'll fix it for free once too.

Try that with an FMF or a Yosh.

He does his stuff in stainless and its nice stuff. MRD is in Riverside Ca. And I'm pretty sure that Eddie Sisneros in Co. has maps for the MRD stuff.

And you'll be able to buy a stack of tires with the money you save too.

Stock is best.

A pipe isn't going to make you that much faster.

Don't be sort sighted...

LOUD BIKES are killing this sport.

There's a reason Honda is selling bikes that are 94 decibels.

Hey moderator you endorsing loud bikes...

I have a very different opinion than you.

Loud bikes arent hurting anyone. Its a friggin pretext to impinge the act of riding your dirt bike. Dust is far worse.

With that said, have you ever heard an MRD? Obviously not. They arent obnoxiously loud. Not all that much louder than the stock pipe the way they measure them, and actually quieter at WFO than a lot of stock pipes.

Personally I have a Thunder Alley...its flippin loud. Not that I like it that way, it just is. But if I wanted a quiet bike as a point, Id ride a two stroke, slowly while feeding bunnies and delivering butterfly kisses to all the lovely lying cheating hateful bastards that choke off my public lands.

I really like the MRD. When you call, you get the owner on the phone and he will answer any questions you have. The system looks awesome and sounds great too.

I also just got to take advantage of the repair warranty after a nasty crash I had. I sent my damaged header and silencer to Dave and within a week it was sitting on my doorstep looking like brand new. Find me another exhaust company that will do that....

the reason Honda is selling 94 db bikes is because alot of people by track bikes and go trail riding in noise controlled ares and those guys are causing all the stink , if your not at a track or you ride in a noise controlled area run a quiet exhaust , simple as that , but motorcycle haters will still hate you

Thats kinda my point. The Wiccans (my pet name for the Eco-Nazis) that worship mother earth have even gone after horseback riders, hikers, bicycle guys....

They don't give a rats ass about motorcycles. They seem to think if you're outside in a wild natural environment and your not naked or an animal you're obviously the devil and should be killed on site!

Loud bikes aren't hurting anyone. Seriously?

How many tracks have you heard of being closed due to dust issues compared to noise issues?

      I just bought a Magura hydraulic clutch for my 2014 CRF450R.  Bought it thinking install would be easy, and I'm not sure that's the case now that I have the product in my hands.  I have searched the forums, YouTube, etc for install help specifically for my model year (2013 and 2014 are same really), and haven't found anything specific for the 2013-2014 model install at all.  Instructions from Magura are TERRIBLE, and are not specific at all to the Honda - generic instructions - so I'm debating if I want to return the product, cuz I don't want trouble or a big install job.  Question: for the 2013-2014 CRF450R install ONLY of a Magura Hymec hydraulic clutch - other model years are different and thus it won't be helpful for other model years - do you have any tips or feedback?  My concerns are below...
      1.  The 2014 model has a sleeve behind the clutch actuation arm that the Magura clutch slave cylinder fits into.  Stock, the sleeve holds one end of the cable, with a nut on the other end to keep the cable end tight in the sleeve.  The Magura slave cylinder, however, slides into the mounting sleeve  - but does NOT have a nut: the tension from the clutch actuation arm pulling on the metal Magura slave cyl tip end is apparently supposed to keep the Magura slave cylinder tight in the mounting sleeve.  Q: Will the Magura slave fit in to the mounting sleeve easily, stay tight, and is there any adjustment needed in order to keep the 4-6mm of freeplay that Magura recommends?  How easy is it to get the Magura slave fitted into the sleeve and the metal tip in place?  Is there enough freeplay between slave and tip end to mount in actuating arm AND the holding sleeve, so that the holding sleeve doesn't need to be unbolted?  
      2. The stock clutch cable and OEM setup runs out of the mounting sleeve (see pics marked "metal starts", and then runs through a metal sleeve that routes the cable through the engine compartment - keeping the cable away from the hot parts of the engine case, so as not to melt the cable insulation (I believe).  That metal sleeve is about 6-8 inches in length.  The Magura clutch cable, on the other hand, exits the Magura slave cylinder at an angle - yet has no such metal routing.  I don't think the OEM metal routing sleeve will accept the Magura cable either, so a) the OEM metal routing sleeve would have to be removed first before installing the Magura - and then b) you have to hope that the Magura cable can be routed in such a way with zip ties holding the hydraulic line that line will not touch or be close to the hot metal engine casing as you route it through the engine.  Q: how easy was it to get the OEM clutch cable and metal routing sleeve out?  Easy as unscrewing the nut on the other end of the OEM cable, on the other side of the black rubber cable flange in my pics?   
      3.  My stock clutch pull isn't bad.  I just like the feel of a hydro clutch.  Any feedback on how much better feeling and easier pull will be with the Magura?  What's your feedback on the difference?  FYI, I'm leaving my clutch plates and springs stock.

      We have a 2016 CRF450R with about 11 hours out. never ridden hard always check the oil and change when needed along with the air filter. Took care of the recall that was required as well. Well when riding the bike was stalled out. Went to try and kick start the bike again. the kick start lever just back up jamming my knee into the handle bars and some how ended up cracking the case right by where the kick start goes through the case. Has any one had this happen or heard of this happening? What is the cause?

      Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it?
       
      Thanks!

      The dirtbike is on it's forth year right now on the same motor job. I have to jump start it. Is it worth me trading for a 2009 650 brute force with7000 miles? Need some expert advice. Thanks

      Just wondering what you guys do to remove black marks on your seat. My 08 crf450r has the red/black seat, and after each ride there are some black marks on the red from my riding pants. Not scuff marks, more like patches of black residue from my pants rubbing on the seat. I’ve tried the magic eraser which seemed to do the trick, but lately they seem like they aren’t coming off. Also tried scrubbing bubbles with a brush and no luck. Not too worried cuz I have an spare OEM seat, but I’d like to keep this one nice. Any ideas? Maybe I shouldn’t wear black pants?
