Description
SpeedWerx Arctic Cat Wildcat Sport / Trail Stainless Steel Exhaust Header
Pick up an easy 4.5 to 5 HP over the stock exhaust manifold with the new Speedwerx Stainless Steel Exhaust Header- depending on year and model and choice of muffler, that’s up to a 10 HP gain overall! Our 304 stainless steel header is simply one of the nicest exhaust parts you will ever see. It features stepped diameter equal length primary tubes, and 2-into-1 merge collector to maximize overall power and performance. All joints are hand-prepped and sand rolled prior to the purge welding process, so you get great looking welds and the smoothest surface possible inside of the tubes. The header is designed to use the stock heat shield with minor trimming, so no header wrap is needed for a clean looking, low maintenance installation. We highly suggest the use of the Dynojet Power Commander V Fuel and Ignition controller with this header, and we have a custom map tuned specifically for our header and muffler combo. The PCV allows us to maximize performance by tuning the fuel injection and ignition timing parameters, as well as re-setting the rev limiter to a safe and reliable 8500 RPM which will give you more top end speed compared to the stock 7750 or 8000 rpm rev limits. (Speed and Acceleration data coming soon!) Fuel mapping and ignition tuning are optimized for 91+ Octane premium pump fuel.
IMPORTANT NOTE: This header is a direct bolt-in for 2016-2017 Sport models, but 2014-2020 Trail and 2015 & 2018-2019 Sport models will require a muffler made for the 2016-2017 Sport, as well as a new exhaust donut and springs. It’s designed this way since the stock 2016-2017 Sport exhaust has a much larger diameter manifold to muffler joint- this allows us to minimize the restriction in this area and maximize the performance potential of these machines. We offer the mufflers in both the L2 Series Aluminum Body, and the Q6 Stainless Steel- see "Related Products" below for recommended components.

Dyno Testing Info:
The dyno sheet shows the stock 14-18 Trail / 15 Sport baseline vs. a stock 16+ Sport vs. one equipped with our new Stainless Steel Header/Slip-On Muffler/PCV combo. The first thing that stands out is Arctic Cat really did their homework on the 16 Sport, as it put up numbers well beyond the 5% gain they have stated! The new exhaust manifold and muffler with the larger inlet help it to perform much better than previous models even though the engine itself is unchanged. Beyond the new exhaust, they have also revised the ECU tune and bumped the rev limiter up to 8000 RPM as compared to 7750 on the 14-18 Trail and 15 Sport, and that enables the peak power to continue to climb to the rev limit. The stock muffler has a catalytic converter built-in like the previous models and is quite heavy at 17lbs, but it shocked us on how well it actually performs- unlike the previous models where our Slip-On and PCV combo netted a nice gain, there was actually little or no gains to be had installing them on a 16+ Sport. That’s where our new Stainless Steel Exhaust Header comes into play- it’s based off the stock 16+ Sport with the bigger muffler inlet, so you guys with the 14-18 Trails or 15 Sports can upgrade the entire system to take the performance beyond what the excellent factory tuning on the 16+ Sport can do. Another big part of the equation is the new Dynojet PCV Fuel and Ignition Controller mentioned earlier- not only does it allow us to maximize the performance by tuning the fuel injection and ignition timing parameters, the REV X-tend feature allows us to reset the rev limiter to a safe and reliable 8500 RPM which will give you more top end speed compared to the stock 7750 RPM or even the 16 Sport 8000 RPM rev limit. The net result is the 14-18 Trail and 15 Sport gains a solid 9.5-10hp with the full exhaust and PCV and loses .2-3.3lbs depending on which muffler you choose, and it keeps pulling on top well beyond where the stock setup noses over before hitting the rev limiter. Those of you with 16+ Sports won’t see as big of a gain since you already have the “good” factory setup, but you can still get the benefits of the full exhaust and the PCV with the extended rev limit- our setup simply makes better power across the board, 5hp or more at some points in the RPM range, plus you can shed 6.25-9.35lbs depending on your choice of mufflers. Stay tuned for Speed and Acceleration Data too, we’ll be hooking up our Vbox GPS data recorder to see how these new parts perform in the real world- we’ve already seen some nice gains with our existing Speed Kit (Slip-On/std PCV/Secondary Spring) that we have been selling for a couple years, so we’re excited to see how these things run with even more power and the speed capability with the raised rev limits!
