Because it the only part of your bike your competitors will see from second place!
New LEXX exhaust is a beautiful option. The kit includes a new mid pipe and mounting strap. I combined this purchase with a new FMF powerbomb header pipe. I am pleased with the new sound of the Bike plus with 3 bolts i can go from quieter trail rider to full flow, screaming racer.
Exhaust looks really good and fits damn near perfect.

Sounds nice. The removable spark arrestor is nice to have. Take it out for the track and get more power. Put it in for the trails
it quiets it down nicely, but still has decent sound. Fit with no problems

I love the pipe with the different settings and the tone is awesome and I can feel the power difference just with the slip on track times are better and bike is faster the only bad thing is it didn’t come with the mid pipe to head pipe clamp

Lexx Exhaust on KLR650
At first, I was hesitant to purchase this exhaust as I have never heard of the brand and also because of the price. But don’t hesitate! Very nice quality and sound! My only complaint would be the exhaust springs. They both snapped on me when trying to connect the slip on the the midpipe. Other than that, it is a great exhaust!

Lexx Slip On Exhaust 2009 Honda CRF250X
Nice quality, would prefer a welded aluminum back hanger like FMF or Pro Circuit rather than a steel band, but could not beat the price. Sounds perfect out of the box, not too annoyingly loud like people with quads that feels louder means more power. To gain full benefits requires: air box mod, upgrade to an aftermarket air filter, 158 main jet, Honda OEM Needle (NCYS) - CCC Mod, Needle 4th clip position, Tusk adjustable fuel screw (2 turns out). Applied Racing Emissions Block off kit & Crank Case vent kit. Runs so much stronger now, from factory Honda has bike set up way too lean and very restrictive with small air intake on air box.

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.
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.
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 .
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?

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.
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.
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.
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

I wanted to know the weight of the lexx pipe on a 2017 wr250f?
A shopper on Apr 29, 2018
BEST ANSWER: Light Like paper i have it on all my bikes would not dare change up not even for free #LOUD🤘 ride safe
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.
So I installed this on my 2005 CRF450x. Without the spark arrestor, it's almost too loud with it being just a straight pipe basically but with the spark arrestor in, it isn't much deeper or louder than stock. Has anyone found a happy median? Would it work to take the arrestor out but put some exhaust packing in it?
A shopper on Apr 9, 2017
BEST ANSWER: I repacked it with a mix of standard packing and steel wool, and still use the arrestor. If you pack it well it does quiet down a bit.
I have a 03 ltz 400 bored to 440 will this go on there?
j p on Jun 23, 2018
BEST ANSWER: Yes it will work fine, being board to a 440 will not have anything to do with the Lexx slip on
What size jets should i use with this exhaust? I am at arround 1100 ft. In elevation and every thing els is stock
Brad F on Mar 4, 2018

BEST ANSWER: No
What's the 3 aluminum slip on pieces for on this pipe?
A shopper on Dec 28, 2017
BEST ANSWER: There is the slip on pipe, a mid pipe between the slip on and stock exhaust, and the exhaust hanger
If i combine this with a fmf powerbomb for a 2004 yzf 250 what jett kit will i need, and can i get from here?
bradford l on Nov 7, 2017
BEST ANSWER: jetting is a trial and error thing. you will need to see how it is running. most likely you will have to lean it out a little seeing that they will get more air into the cylinder and create more back pressure. we do not have a set type or size jet you will need to run for that.
What jets are needed when putting lexx mxe slip on on my 660r raptor?
A shopper on May 3, 2017
BEST ANSWER: You shouldn't need any. I always start with the exhaust when upgrading and go from there.
Will this fit a 2017 Husqvarna FX 350? It shows up as fitting the 17' ktm 350 xc-f but not for the fx. The bikes are 99% the same so I think it will mount up ok but I would rather confirm before ordering. Thanks!
Stephen H on Mar 27, 2017
BEST ANSWER: I have the Lexx Slip-On Silencer with Mid-Pipe on my 2004 YZ450F and it fit perfect. I know its a completely different bike; however, there is an included attachment that can adjust to a vary of different sizes for the mid pipe. If the bikes are 99% the same you'll be fine. I would definitely recommend the purchase!!! Besides, when dealing with RM you can't go wrong.
