The RS-2 is a really versatile and very potent exhaust; it is one of Yoshimura's most popular off-road exhaust systems and has proven its value on the race track for years. It is basically an evolution of the original Yoshimura TRC design but with a slightly different (pyramidal) shape that features increased volume. The volume enables a quieter system and larger core, which in turn increases power and power delivery. With gains throughout the powerband and the durability of high-grade stainless steel mid-pipe, you can't go wrong with this system.
The powerful RS-2 exhaust design in a convenient slip-on muffler package.
New diamond-shape slip-on allows for more packing material creating lower noise.
Muffler shape increases durability and performance from muffler packing.
Two-stage large race baffle allows optimal performance throughout the RPM range.
Slip-on comes with a 304L stainless steel mid pipe.
Two-piece stainless steel end cap allows for installation of various inserts.
Tapered front cap allows muffler mass to be moved forward for better center of mass.
Step-by-step directions and all necessary hardware included for an easy installation.
Mufflers come with a 96dB U.S.F.S.-approved spark arrestor installed in the muffler.
Notes: Optional Yoshimura 94dB and 99dB sound inserts available separately.
Dont waste your money on another exhaust even if th yoshi is 200$ more it pays off you are paying for top notch quality. Very silent jet so powerful

Yoshimura RS-2 Comp Series Slip-On Exhaust
I put this on my 04 Yamaha YFZ450, it is a great pipe, its power is amazing on the low end, it pulls great though the power band. It doesnt fall sort anywhere and it has a great sound to it. I had a different after maket pipe on my quad before and it didn't have a spark arrestor, it was super loud so loud it hasnt fun to ride with it, and its power was all on the upper end. This pipe will not disappoint!

i bought this slip-on a week ago and now my 350 raptor has a better sound. but i advise to take spark arrestor out. this is a quality exhaust and ive noticed better power in 3rd to 6th gear. and oh my god its such a good looking exhaust. lets not forget it took only 5 minutes to install.
Why won't it work on 93' and 94' Honda XR650Ls? There is no difference in all year models. All parts are interchangeable. I don't get it.?
Also, exhaust systems from other companies fit on all year models...including 93 and 94.

The stock Honda Exhaust is the same 1993-2015 on the XR650L so I checked with Yoshimura just to make sure and here is what they had to say.
"We did not do any fitment checks on the 93 or 94 XR650L models, only on the 1995-up. If it is the same muffler from Honda, it is probably going to be the same for the Yoshimura as well. But since we did not do the fitment checks on them, we cannot officially confirm the fitment".
The spark arrestor is easily removed from the Yoshimura RS-2 Comp Series Slip-On Exhaust.
1. Using a 3mm Allen key remove the bolt that secures the aluminum ring and spark arrester to the muffler.
2. Remove the spark arrester from the muffler.

No, unfortunately Yoshimura only offers the Yoshimura RS-2 Comp Series Slip-On for Kawasaki KX250F's years 2006-2009. FMF and Pro Circuit both offer great Slip-On's for your 2004 Kawasaki KX250F which you can find here: http://www.motosport.com/dirtbike/dirt-bike-parts?textsearch=slip+on

I have a 2012 suzuki ltz-400, would I need to re-jet my carburetor?

Normally when installing a slip-on only minor jetting changes are needed, if any at all. If you ATV is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the ATV to see how it is running then tuning your carburetor from there if necessary. Jetting can be very tricky, there isn't one setting that will work everywhere with every ATV. I would recommend taking your bike to a local ATV/Motorcycle shop with a service department to have it properly jetted.
Unfortunately fitment cannot be guaranteed due to manufacturing tolerances from the different companies. It should fit as the FMF power bomb can replace a stock header but the fit cannot be guaranteed. For best fitment go with an FMF muffler on your 2007 DR650.
Do u have to do any updates once u put this on a crf150r.?
Do u have to re jet or anything if i got this for a crf150r.

When adding an aftermarket exhaust system to your CRF150r, more than likely you will need to re-jet. It will vary based on location and your elevation. Your best bet to obtain the correct jetting, would be to call Yoshimura @ 1-800-634-9166 and they can provide their recommended jetting for your location and elevation.
