’85-’01 CR500 Hard Anodized “HORSEPOWER” Exhaust Manifold

Replaces Honda OEM Part #’s 18352-KA5-691, 18291-ML3-791 and 18359-KA5-690


These Honda CR500 Exhaust Manifolds fit the 1985-2001 CR500 engine.

These Exhaust Manifolds are constructed of billet 6061 T6-511 aluminum and Hard Anodized to Military Spec (MIL-A-8625). This Hard Anodizing puts a strong coating protecting the Manifold from abrasion and corrosion. These Hard Anodized Type III Black and silver colors will not fade with high temperature like standard Type II anodizing. These manifolds comes with the 4 high-temp FKM O-rings installed. Better materials make a better product.

Hard Anodizing (Type III), is done under more exacting process conditions resulting in a harder, denser, thicker, coating that will be exposed to extreme wear!

Dyno proven to provide up to +3.9hp and +1.4lbft tq depending on your engine build.

Don’t make the mistake and buy another manifold you will have to replace because of inferior fitment, lesser quality materials, poor coatings or poor customer service.

Why Choose Our Honda CR500 Exhaust Manifold?

Looking for more reasons to switch to the MSV Racing Power Sports Honda CR500 Exhaust Manifold? Here are a handful of benefits you might consider. 

  • There are high temp FKM O-rings on the manifold spigot that seal the expansion chamber and stop the black drool that can leak with the OEM flange. This also allows easy pipe removal and install without having to re-seal. 
  • A 4th FKM O-ring on the back of the flange eliminates the gasket and stops the need to buy a gasket or scrape one-off when doing top end work, etc.
  • The Type III Hard Anodizing inhibits carbon deposits. They also retain their color with zero fading.
  • All versions of our CF500 Exhaust Manifold have a .500″ lead-in taper in the exhaust port hole on the flange side that allows for larger exhaust port matching to promote more power.
  • They are less than 1/2 the weight of OEM flange. (Did we mention, less than half!)
  • Perhaps most importantly, the MSV Racing Power Sport CR500 Exhaust Manifold looks awesome.

  1. Kieran Williams

    Had my msv manifold for about a year exceptional quality and really does what the oem cant do create a perfect seal on the exhaust, great service provided

  2. Chad

    Highly recommend this manifold for your cr500.

  3. Steve

    Perfect in every way. Fit, service, spares, postage. Incredible product

  4. Victor Kleymush jr.

    Bought the MSV Racing
    exhaust manifold a while back and it works great! Not a drop of oil under it unlike the stock one and the quality, can’t beat it to any other. Well built, no comparison to any. Thank you for a great product

  5. Aaron Vaughn

    Been riding CRs (125,250, and 500s) for years. Always having the annoying spooge leaking from the exhaust manifold. What MSV has done is design and provide what we’ve all been missing for decades.

    I’ve had my 2001 CR500 Snowbike equipped with one of these beautiful, effective, and cost friendly parts since 2017. This bike sees wide open throttle and high temperatures all day long. The MSV CR50 Exe. manifold doesn’t leak a drop. Upon removing the exhaust for some cylinder porting upgrades the manifold looked great considering all the vibration the CR5 gets. Cheers!

    Now every CR500 I rebuild gets one. Take a look at the Phi impeller for another top notch part!

    A must have upgrade for the CR500! Looks great and preforms even better then it looks. No more dealing with splooge coming from the exhaust flange like the OEM flange.

    Love the msv products here are some pictures with the msv manifold on it looking over the Australian bush.

    If you have a CR500, the MSV exhaust manifold is a MUST! Been struggling with properly sealing the exhaust pipe and stopping it from leaking and getting oil all over the front cylinder. Bought OEM manifold and seals twice and still leaked. Install this on my bike and haven’t had a drop come out anywhere. This manifold is well worth it.

    I only have one ride on it, and it looks fantastic. Production quality is first rate! No more leaks. Used dielectric grease on install per instructions. Durability remains to be seen. I realized after I ordered that a stainless version is available. Probably should link the two on the site so others know as well. I would’ve probably gone stainless if I had known.

  19. Bill B. (verified owner)

    very nice fitment

  20. Patrick Carroll

    Works perfect ! In my opinion, best manifold for the cr 500 on the market !
    Don’t waste your time with standard ( warn out) parts.
    I’ve been running it for a solid year & half 70 hrs total time. Thank you MSV Racing!

    Product arrived as advertised

  26. Joseph Long (verified owner)

    There’s a reason why there are so many good reviews on this product. It’s because this manifold just works. It seals up perfectly, because I wasn’t able to see any smoke coming through this manifold and after a long day of riding out in the desert, there was absolutely ZERO oil oozing around this manifold and that makes me a very happy customer!

  27. Adam R. (verified owner)

    Quality and fit excellent.

    Awesome product

  30. Robert Dickinson

    A really good, solid product. No leaks at all, no drool on the cylinder. proper quality bit of kit. The only downside is that the rubber O-rings have expanded / degraded and snapped when i have tried to remove and re-fit my pipe. looking at another review on the replacement rings it seems the same issue, when the raw fuel hits the rubber it ruins it, its probably fine while its still on the bike in place but means you will need new seals if you plan to remove and replace your exhaust. Not a massive issue at $5 per set, but a timing problem for me waiting for them to come to the UK 🙁

    If buying one, which you certainty should, just get a spare set of rings for good order.

  36. Doug Girt (verified owner)

    Tolerance are awesome, the only issue was my PC pipe would not fit. Not your fault at all. I was the fact that the o-rings actually sealed the pipe.
