Installed on my 2016 CRF250r. Whole process took under 2 hours. Instructions were straight forward but definitely need an extra set of hands. No power loss. Looks great!

nice way to convert stock muffler,had no problems with install,very happy with overall part and looks.
Installation was fairly easy and it fit perfectly on my 2017 yz450
tech on phone helped with purchase got the right one for bike
As A Tech in the car industry. the installation was fairly easy. I can see if your not used to drilling, and using a center punch. that this tip could be a challenge. However if you possess basic skills you can do this yourself. it took me an hour and 15 min. As for sound and performance, i noticed a slight tone difference in my sons kX250F. but he says the performance is still all there. which is great I did not have to re-map the fuel trim. For the money, it is for me the best bang. repacking will be easy because kawasaki has actual bolts on the intake side of the exhaust. Thanks to pro Moto billet for producing this accessory.
Ordered for YZ426 for the spark arrestor so I can ride public land. Install went well except for the supplied self tapping screws. Screws are too soft and hex head strips out easily. Ditched the screws and used rivets instead, works just as well. Tapping the holes beforehand would help here. I was expecting a blue end cap because that's what the website says for the part number, but received black. Thought about returning but installed anyway; not a complaint really, just FYI. Looks fantastic, solid build, USFS legal. Very happy and now looking at buying a quiet insert to get the dB levels lower so I can pass inspection for hare scrambles.
This is the 2nd Pro Moto Billet spark arrestor I've had on a 450. They're very simple to install and on a bike that doesn't need more power it's a cheaper way to go that getting new exhaust. Just received on for my son's KMX 50sx and it's a great fit too.
There should be more of a warning to buyers of this product that it is not an easy installation. Stock silencer had to have a substantial mod for this to fit. Weird self tapping metric "torx" (worst type) fasteners require unusual 13/64" drill bit. Maybe they should include a bit into this expensive package to save you a trip to the hardware store for this odd sized bit ?
Not an easy install!
Works and installs great. Built of thick aluminum, so should last and take some abuse. An easy more affordable way to be legal.
This is a cheap way to make your bike legal for off road use where a spark arrestor is required. Only annoying part about the install is drilling out the holes all the way around the billet aluminum housing, Not sure if this is the case with all of the end caps, but it was on my YZ250F. It wasn't that big of a deal, just a little time consuming. Looks great and keeps you legal when riding off road.
Instructions are clear, just make sure you have some high temp silicone. If you are looking for a cheap way to make your MX bike usfs approved this is it. Taking the screen out for when you don't need it takes less the five minutes. Looks great too. I feel like more companies should offer products like this.
The hardest part of the the whole job is getting the stock end cap off. The rest is butter!
Just bought a used 06 crf250r. I needed a sparky for California restrictions. I can see no difference in power. I like the way the look and now the exhaust tucks behind the side panels. Use lock tight on the Allen bolts. Because I have a dual exhaust it took a little bit to install both caps. Installation was easy and the instructions easy to understand.
Got the part right away, super fast shipping. Instructions were straight forward and fitment was great. Careful not to strip the heads of the self tapping allen bolts, they're pretty soft.
not a bad buy and functions as it should. i used this on my 2015 ktm 500 ecx to replace the super restrictive end cap that comes on the bike from the factory. it woke the bike up gave it more bark and better throttle response. i am currently running it with out the quiet insert and it is loud! if you like the quiet Ktm sound check out the end cap by power quiet sports. over all i am happy with the buy and so far it hasn't melted my factory turn signal. you will probably have to advance your tps sensor to get some more fuel after install.
Easy to follow instructions. All parts were easy to install. Look great! Tom
You would be very surprised to see how much this improves the look of your bike. The green is amazing on a 2013 KX450
I bought this on the advice from friends for an 07 YZ450F. The instructions were pretty straight forward, though I wasn't planning on having to drill the end cap before I received it. I had actually expected it to be pre-drilled for the specific model.. but it wasn't. Anyway, it drilled out pretty easy (I used an air powered drill and a quality drill bit). I tapped the end cap into the stock silencer housing (real nice fit) and drilled it in place. The drill bit listed in the instructions is about the same size as the holes in the silencer. I was worried the drill was going to drift, but the existing holes kept it all lined up. Once I drilled it, I popped it back out and cleaned up any shavings. Then put some high temp silicone around the edge and tapped it back into the housing with a rubber mallet. The Kit comes with self tapping hex key screws. They are a little tough at 1st, but no real issues on install. I was one screw short, but I may have lost it (I opened the packaging and they flew everywhere). I ended up using one rivet which I think is a good precaution. A friend of mine says he found one in the desert and he knows of another rider that has lost 2. He says he knows of a few people who just lost the end portion of the end cap (the part held on by 3 bolts). Loc-Tite is your friend people... I also used that on the self tapping hex screws.
Sounded stock. Didn't mess with the power at all. And lasted longer than I kept the bike.
Good product. Fits well, Looks good, a bit pricey tho.
Install of the end cap was easy. Getting the old one off was a b*%$#!
Just be sure to correctly select the Year/Make/Model of your bike before ordering so we can be sure to send you the correct spark arrestor for your bike. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
1) 1105 adapter
3) M6 x 1 socket head bolts
8) Self-Taping screws
1. Remove the Muffler from the bike
2. Remove the bolts holding the stock end cap in place.
3. Using a sharp knife cut the silicone around the perimeter of the stock end cap. This will make removal easier.
4. Pull the stock end cap out of the muffler. If you are having problems removing the stock cap,
using heat from a heat gun on the canister sleeve may make this easier.
5. Remove the O-Ring from the stock end cap and place it on the new end cap.
6. Trim any fiberglass packing material back so it is flush with the muffler canister.
7. In order to allow the inner core to align with your new Endcap Base, loosen the five bolts on the opposite side of the canister. (See Photo A)
8. Install the new end cap base into the canister. Check that the end cap base is pushed up tight to the muffler and aligned parallel to the stock canister. Due to the odd shape of the canister, you may need to lightly tap the base into the canister using a rubber mallet.
9. Using a 13/64” drill bit, drill out the holes in the end cap base one at a time and install the self-tapping screws. Make sure that the end cap is pushed up tight to the muffler before drilling each hole and installing each screw.
10. Once the new end cap has been installed onto the canister, tighten the 5 bolts from Step #5.
11. Insert the spark arrestor screen.
12. Install the nozzle with the three M6 bolts.
