Exactly what you would expect for $200
It's a good pipe for the money, its exactly what you pay for. Fit was good it takes a bit of finesse to get the mid pipe on. I used JB weld gasket maker for exhaust, it sets up in 30min. The bracket that holds the silencer on does not fit snug around it. If you dont use gasket maker there the pipe will rotate in the bracket. I needed a silencer with a spark arrestor last minute for an NGPC race it was the only one that would get to me in time, it did hold up to the race. I did not notice any power change, it was a little bit quieter. I will be ordering the race tip and screen for it to see if it changes the power at the bottom, mid or top. Again I can not stress enough the pipe is exactly what you would expect for $200.

I read other people’s reviews of this pipe so I was hesitant to buy it. When I got it it took me about 15 minutes to instal it, I had no issues with the springs. It looks and sounds great! Greatly improved the low end performance of my bike!

Great Performance and Price
I really like the quality and performance of this silencer kit and it looks great on my KLR650. Pipes fit together well and installation took a leisurely hour. I couldn't wait to get rid of my old, rusty, unsightly OEM unit!

Regarding fitment, I would highly recommend upgrading the 2 supplied springs to a stronger set. I would invest the $8-10 and install them using a purpose-built spring puller; makes the job quick and foolproof. Also, I had to make a slight trim to my rear fender to provide just a bit of additional clearance so the silencer didn't touch any of the plastic directly. This was barely noticeable.

Overall, very happy with look, fit, and performance on my KLR.

Honestly I was a little bit skeptical about purchasing the exhaust because of the price, but I was mistaken and it is as equal or better than the high-end exhaust the cost twice as much!

Better than stock at a low price.
2 weeks in, so far so good. Far lighter than stock, looks and sounds way better. No noticeable power gain but I haven’t re-jetted yet. Easy to install (except the springs...)

Will the Lexx slip on work with this?

Lexx MXe Slip-On Silencer With Mid-Pipe
Lexx MXe Slip-On Silencer With Mid-Pipe
FMF Power Bomb Header Pipe
FMF Power Bomb Header Pipe
BEST ANSWER: Yes, I have this same combination and it works great. Just use some silicone seal on the joint. No clamp required. And replace the Lexx springs with some good-quality exhaust springs like FMF.
does this come with a spark arrestor?
Blake S on Aug 22, 2016
BEST ANSWER: Yes it does. It includes a USFA approved Quiet Core spark arrestor Insert that brings sound levels down below 96db.
2017 KTM 350 XC-F
Will I need any additional hardware for this setup to stock header pipe? (i.e springs, silicone, ect.?)
joshua c on Feb 23, 2019
BEST ANSWER: No, but I recommend the upgrades insert . the spark arrestor breaks inside. RM. Has the upgraded insert on the site
Got an 06 wr450, put this pipe on and it messed with the jetting so I need to rejet. Any recommendations on what jet size to go up to?
A shopper on Aug 18, 2016
BEST ANSWER: It's hard to recommend what to adjust without really knowing how the bike is running. The best advice is to purchase some some bigger main jets and pilot jets than what you currently have. Also you have adjustments on the needle height and air fuel screw. when making adjustments best to adjust one thing at a time and see how the bike runs. Pilot will effect idle and right off idle. needle height will effect low to mid and main will effect mid to top. Hope this helps and good luck.
I have a 2015 Yamaha yz250f fuel injection ,will I need a tune if I add the lexx slip on ?Currently has a stock exhaust
RONALD H on Apr 16, 2019
BEST ANSWER: I put it on a klr 650...thought it leaned it out a little so I put a het kit in this year
Does it make the bike louder?
A shopper on Feb 21, 2017
BEST ANSWER: It depends on the size tip that you use. I have the 32 mm tip on it without the spark arrestor insert and it is slightly louder and throatier than stock, but not unpleasant. Actually it sounds great to me. I have not tried the full race tip that comes with it. I believe that is 36 mm, and others have said it was too loud with that tip.
Does it fit on the stock headers?
Austin W on May 9, 2017
BEST ANSWER: Yes it is made to work with the stock head pipe
Does this exhaust cause popping on deceleration on a KLR 650?
A shopper on Mar 19, 2018
BEST ANSWER: Hello, On my 2005 KLR650 I have no issues with decel. popping. I have NOT done any carb or airbox mods either. P.s. you didn't ask, but I love this can!
Do i have to jet with this pipe?
A shopper on Aug 6, 2017
BEST ANSWER: You don't have too but your bike may run a litle lean if you don't depending on how restrictive the stock muffler is. I rejetted my Honda 250X using suggested jetting provided by Rocky Mountain ATV MC's website and my bike runs fantastic! Before the rejetting it ran a little lean because the stock Honda muffler is quite restrictive.
Other than some silicon sealant on the midpipe, do I need to reuse the actual stock clamp gasket with this slip on, or just the little bit of sealant? Thanks -
A shopper on Sep 16, 2017
BEST ANSWER: There is sleeve bushing that adapts the new mid pipe to the head pipe using High Temp RTV Silicone on all mating surfaces. loosen the head pips at the head to help align everything, no clamp needed .
Have 2017 klr 650 if I use lexx slip on exhaust do I need to re jet carb or stock carb ok?
David H on Aug 16, 2018
BEST ANSWER: I have found that taking the air box lid off along with re-jet works best with lexx exhaust. but to answer your question you would probably be ok not to re-jet if you just put on the exhaust on by it self. if your looking for more performance you will notice the difference if you take off airbox lid and re-jet
I have a 2005 Kawasaki KFX 400, Completely stock, I just put the exhaust on today and when I started it up it started to bog and back fire like crazy. SO I think I might have to rejet it but don't know what kind of jets to go with? 223 ft elevation ....... SO PLEASE HELP ME
Dalton M on Feb 9, 2018
BEST ANSWER: I have a different ride but you will need to reject, it would probably be the same as any slip on so check all the forums or thumper.FYI the end cap screws have all vibrated put of mine so I got screws at ace HW and used locktite. Screw holes try to strip out and color will turn black to brown bot still a great value and good sound.
Got this slip on for an '06 KTM 525 EXC. Problem is the midpipe seems just a little too small to slip on to the header pipe. Should I get the midpipe enlarged or should I just pull up my panties and try harder?
Jeremy J on Apr 1, 2017
BEST ANSWER: Either Option works I have a 08 530 and i had to muscle it on a tad. Maybe take a soft mallet and tape it on. Otherwise if you have a torch heat up the slip on and it should barely slip over the header.
I have a 2004 YZ450F with the stock header. Is this collar required to install the Lexx MXe Slip-On Silencer With Mid-Pipe on it?
Daniel M on Oct 31, 2016
Lexx MXe Slip-On Silencer With Mid-Pipe
Lexx MXe Slip-On Silencer With Mid-Pipe
Lexx MXe Replacement Exhaust Collar
Lexx MXe Replacement Exhaust Collar
BEST ANSWER: Hi Daniel. The Lexx silencer comes with three different collars. One should fit the stock header perfectly and then I used high temperature silicon around the collar to seal it up good. I'm very pleased with the silencer so far.
When I buy the exhaust do I get all the interchangeable tips? Or do do I buy them separately?
Jordan W on May 31, 2017
BEST ANSWER: The tip is the same. What is interchangeable is the insert. You get a spark arrester, and a quite core insert.
What the best pipe for a Honda 250x?
A shopper on Aug 18, 2016
BEST ANSWER: I found this pipe an excellent low cost alternative to other aftermarket slip ons. The build quality is great and the fitment is excellent. The exhaust note is not much louder than stock with the spark arrestor in place. there is a slight performance increase with is much greater if you do the airbox modfication and re-jet your bike per the instructions on the Rocky Mountain website (this really wakes up your bike). The down side is this pipe is not much lighter than stock. If you want a light weight upgrade then I would suggest you spend more and purchase another slip on from other manufacturers on their website.
Does this come with exausht clamp?
Tyler G on May 18, 2019
BEST ANSWER: The one for my KLR 650 did have a clamp.
Is this trail legal? whats the decibel reading on it?
sean o on May 29, 2018
BEST ANSWER: yes it is trail legal as long as you have the baffle/spark arrestor in it. Not sure of decibel reading but I ride all day with mine and its not too loud. very loud if baffle is removed! hope this helps.
Anyone have a weird smell on the 1st couple rides? Wondering if its the packig in my new lexx slipon or if its my new radiators. Only 2 things changed
branden w on Jun 16, 2017
BEST ANSWER: It may represent the oil or protective coating applied during manufacturing as the muffler goes through its first few heat cycles. It should not be there after this burns off.
Will this mate with the FMF powerbomb header? Thanks
Jason L on Aug 19, 2019
BEST ANSWER: No. This will not work with the FMF header.
How heavy (lb) is this exhaust?
Kira K on Jan 28, 2019
BEST ANSWER: Not sure of the exact weight. It is lighter then the factory exhaust.
How come my mid pipe is too big for the header and my coupler is too big for my mid pipe?
Wade H on Sep 22, 2018
BEST ANSWER: Wade,
Are you sure you received the correct item for your brand of motorcycle. My son and I both installed this item on our KLR 650's and it fit perfectly.
Dan
Is this pipe compatible with the fmf power bomb header?
Nathaniel G on Aug 26, 2018
BEST ANSWER: FMF definitely is the pipe to go with but for the money the Lexx pipe does a fine job. Tone is good but not as deep and crisp as the FMF. I did a combo on my 2004 ktm and went with the lexx pipe and R&D power bowl. Man what a difference in power and throttle response. You can get both or spend 400.00 bucks and get a pipe.
Does it come with a mid pipe, mine didn’t. Or is it not in the kit.?
Brian L on May 29, 2018
BEST ANSWER: Mine didn’t either but should have. I called RM and they told me it was shipped from s different warehouse. It arrived a few days later. Great service from them!!
400ex 2005, if I install this pipe what would the recommended Jetting be? Stock ATV
robert d on May 3, 2018
BEST ANSWER: I put this on my 2007 400ex and ordered the dyno jets kit it will recommend what jet to put in it and where to set the new needle depending on where you live and the sea level your at.
Does the 46mm tip give more power then with out a tip in it at all??
A shopper on Mar 20, 2018
BEST ANSWER: I only ride with the tip in because I don't like extremely loud bikes. My only advice is make sure to loctight all end cap screws and check screws often . I have had all screws come out over about 3000 miles. Still love the LEXX.
I just bought this exhaust today and I installed it and it came with the quite core and came with spark arrestor so how do I take the spark arrestor out and make it louder without the spark arrestor?
Dalton M on Feb 6, 2018
BEST ANSWER: Undo the bolts around the end cap it will pull out then replace the end cap there is a 40mm cap that slightly improves the bottom end response not as loud as the open exhaust
On a 2016 klr650, is a reject required?
Dakota H on Feb 1, 2018
BEST ANSWER: No not at all no rejecting need slip on an go. Had mine for 2 years no problems yet. Knock on mid pipe lol
