FMF PowerCore 4 Slip-On Exhaust

  

FMF’s motto is “Feel the Power” and with the Power Core 4 slip-on, you can feel the power without breaking the bank. A slip-on exhaust is easily one of the most cost effective ways to add gains across the entire powerband. Modeled after their championship winning Factory 4.1 system, the Power Core 4 is for the core off road or motocross rider offering world class performance coupled with rugged made-in-America durability.

 

The FMF Power Core 4  includeds a spark arrestor. If you ride in the woods, you’ll need a spark arrestor. Instead of buying an aftermarket insert for your stock exhaust you’ll have everything you need in one competitively priced package.  The FMF Power Core 4 offers better looks, weight savings, and of course, more power!

 

Features:

  • Similar power gains to FMF’s high-end Factory 4.1 Slip-On
  • Included spark arrestor
  • Aircraft quality aluminum canister with stainless steel components makes this more durable and lighter than stock and other slip-ons

I paired the PowerBomb with a PowerCore 4 and am super impressed. Incredibly easy install and really opened the bike up.

Sounds amazing

I put this exhaust on with a power bomb and the sound is 100x better than the stock system and adds a little power as well. Definitely recommend this for any DRZ.

2011 WR450F Installed on

Shipping and service is always excellent with mcss, the product itself is what i expected, looks amazing, sounds amazing, gives me a little more power, or at least feels like its snappier. Airbox gutted, jd jet kit, etc.. I run in Supermoto trim, and im a little worried about getting grief from the police in the small town i live in, because of the sound of the exhaust. Its pretty loud, i love it, but its pretty loud.

2015 XT250

Fits wonderfully. Easy install (took about 15-20 minutes). Amazing sound and a noticeable performance difference in the lower gears. Must have upgrade. My only recommendation is to get an additional heat shield or insulation for the pipe from the muffler forward as it'll getcha if you're not paying attention to it.

I got this pipe and it works perfectly. I'm on a xt250 and while this doesn't give you a ton of power it really helps get more power out of that engine. Sounds beautiful too.

Mix review...

I would rate motorcyclesuperstore.com OUTSTANDING! The pipe on the other hand failed in less than 3 months on my xr650L and FMF didn't want to honor the warranty when the weld on all three sides separated and the metal even tore about an inch long. As far as the pipe its an "ok" pipe but it failed so quickly I am not sure I would recommend this pipe unless you don't care about having to get it re welded.

A must have upgrade for a 2014 Yamaha XT250

Purchased this slip on muffler for my 2014 Yamaha XT250 and I could not be more pleased. It was a perfect fit, only took around 10 minutes to install. Sound is excellent and I got a noticeable difference in torque in second and third gear. I would definitely recommend this muffler!!

FMP Power Core

Bought the FMF Powercore for a CRF 230F and was extremely pleased with the results. Easy simple to install. I had the bike re-jetted by the local Honda dealer after installing the muffler. Was impressed by the performance increase and it sounds great. Looking at buying one for the daughter's 150F.

FMF power core 4 slip on

Bought for my 2002 CRF450r. I love the sound, and the look. Very satisfied with the product ONCE INSTALLED. Bolts provided were not long enough, had to go to the hardware store to fix that problem. And PLEASE get rid of that stupid clamp and install a welded bracket for goodness sake. Give product 9 out of 10 only because of that clamp. Very reasonably priced.

Perfect Exhaust - Sweet Price

Not the top of the line FMF model but that's ok, this exhaust fit my 06 Honda XR650L just right on the first try. The sound is just what I was hoping for- deep, crisp but not too loud. No dyno results to confirm but it honestly feels like the bike gained maybe 4hp and the throttle response is perfect.

HOLY POWER!!!

I own a 98' XR400R and I was disappointed with the "power output" with the stock exhaust and jets. So, I bought this bad puppy and re-jetted my bike and WOW!!!! Instantly I felt and heard the difference. My top speed improved! This pipe also sounds great! And for the price you cant go wrong!

FMF powercore 4

Instant improvement overall in performance. I had done the smog block off, rejetting, air box mods and replaced filter with K+N, but it needed the FMF Powercore 4 to make it all come together. I would highly recommend it to anyone who has a x0l.
