IMPORTANT: Read instructions carefully before installation.
1. Remove stock exhaust, Y-pipe, silencer, and outlet deflector.
2. Install SLP flange plate onto cylinders using stock flange studs and tighten using stock nuts.
3. Unclip hood cable from the hood. Remove screw attaching cable to the bulkhead. Measure from this screw hole
towards the PTO side 2”, mark and drill a new hole using an 11/64” drill. Use stock self tapping screw to reinstall cable to
the bulkhead (see illustration #1).
4. Remove stock rubber pipe support located on the mag side shock tower. Relocate the rubber support to bulkhead by
measuring from the front side of the shock tower support crossbar towards the front of the sled 2” and mark. Place the
rear edge of the rubber support on the mark, then mark and drill two 3/16” holes and rivet into place with 2 large head
rivets provided (see illustration #2). Note: When reinstalling the rubber support make sure that the raised side of the support is towards the center of the sled.
5. Remove stock spring tab located in the front of the bulk head and relocate to the existing hole located 5 1/2” in from
the front PTO corner of the bulk head (see illustration #2).
6. Cover shock tower and area on the side of the belly pan closest to the pipe and silencer with reflective heat tape (provided). Cover the PTO shock tower in areas closest to the pipe with reflective heat tape (illustration #3). All of the wires
and CDI Box located behind the silencer will need to be covered with reflective heat tape.
7. Relocate coolant bottle to the inside of the oil bottle next to the CDI bracket (see illustration #4).
8. Remove all foam from the right side of the hood and replace with reflective heat tape (illustration #5). Use the zip tie
provided to tie the exhaust valve cable to the mag side cylinder exhaust valve vent hose (see illustration #6).
9. Remove stock silencer support bracket from chaincase.
10. Roll the sled onto its left side place the template provided onto the belly pan to mark the transfer tube outlet hole (see
illustration #7).
11. Using a 1 3/4” hole saw drill the transfer tube outlet hole and debur the hole.
12. Install transfer tube outlet plate from the bottom of the sled up. The angle portion of the plate should be on the bottom
with the long side towards the front of the sled. Using the plate as a template mark the two holes and drill using a 3/16”
drill bit. Rivet the plate into place with 2 steel rivets provided and place rivet washers on the inside of the belly pan.

13. From the spring tab locator hole on the pattern measure 3/4” down the chaincase gaurd (see illustration #8). Drill a 3/16”
hole and rivet the spring tab provided onto the inside of the belly pan with a rivet washer on the inside (the spring tab needs to
be pointing up).
14. The center of the raised portion on the OEM outlet plate inside the bellypan will need to be flattened for transfer tube clearance.
15. Run a bead of silicone around the outside edge of the SLP outlet deflector plate and install to belly pan from the bottom of
the sled and bolt into place using the stock bolts (see illustration #9). Using the plate as a guide drill a 3/16” in the back of the
plate and rivet into place.
16. Install the transfer tube and spring to the spring tab.
NOTE: Silicone all joints on the bypass tube and from the outlet plate to the silencer using a high temp silicone such as Permatex Ultra Black 598.
17. Install spring tab provided using the upper front chaincase cover bolt. Place the spring tab in the 12 o’clock position (see
illustration #10).
18. Run a bead of silicone around the bottom edge of the silencer outlet tube (see illustration #11) Set SLP silencer into place
and bolt the front of the silencer to the stock silencer support using SLP vibro-support with the 1/4” bolt provided (see illustration #12). Place on the stock rubber mushroom into the bracket at the rear of the silencer and spring into place.
19. Install mag pipe (pipe with logo) and spring into place with springs provided. Then install PTO (pipe without logo) pipe and
spring into place with springs provided. Spring PTO pipe to the stock spring tab in the front of the bulkhead.
Note: Check the tightness of the clamps located in the midsection of pipe approximately every 100 miles for the first 300 miles
then periodically after that.
Spring Tension Adjustment:
Spring loop adjustment is suggested for proper spring tension to prevent leakage and wear (low tension), allow adequate flex
(proper tension) and prevent spring breakage (excessive tension).
When system is installed the spring can be judged for proper tension. The winding spacing at the center of the spring will
indicate tension. When proper the two center windings will have .040” to .050” clearance between them. This is easily tested
with a feeler gage.
If tension is incorrect, the loop on the pipe or silencer can be bent in the direction needed to increase or decrease tension. Attach a vise grip firmly to the loop and bend.
Caring for your ceramic coated pipes and/or silencer:
Ceramic Coating is an aluminum matrix applied to your exhaust system to provide a thermal barrier for more
consistent performance. It is a coating which requires little maintenance to keep your pipes and/or silencer looking like new.
Upon completion of new installation, wipe the ceramic coated parts of the exhaust system down with brake
cleaner. This will prevent oils and grease (usually in the form of fingerprints) from burning on and staining the
exhaust during first initial startup.
To maintain your ceramic coated system, wash it with soap and water periodically (especially necessary after
trailering it to and from your riding area on roads that have been treated with salt and other ice removing chemicals). Salt and other ice removing chemicals will attack and eat away at the ceramic coating. This will result in
rust coming through the coating. Typically you will notice this rusting after your snowmobile has set for a period of
time without the exhaust system being brought up to running temperature.
Periodically polish your ceramic coated pipes and/or silencer after each washing with an aluminum polish
such as Mothers, Maas or Blue Magic aluminum polish that can be found at any automotive parts store. Do not
use any acidic cleaners! For stubborn stains use fine 000 steel wool, then use a soft cloth with polish. Failure to
maintain your ceramic coated pipes or silencer can result in damage to the ceramic coating for which there is no
warranty coverage. A little care will insure that your pipes and/or silencer will continue looking like new for many
years.
Note: In areas of the ceramic coated system where skin temperatures exceed 1300 degrees F, it is normal for the
coating to turn dull gray. These areas should also be washed and polished periodically.

IMPORTANT NOTE: CARB TUNING SPECIFICATIONS
INCLUDED IN THIS SECTION ARE A BASE LINE AND
SHOULD BE ADJUSTED AS NEEDED FOR YOUR
PARTICULAR ATMOSPHERE. USE EXHAUST GAS
TEMPERATURE GAUGES OR MONITORING PLUG AND
PISTON COLOR FOR TUNING GUIDE.
Fuel Requirements:
0-3000’: Mountian Cat: Race/premium blend of 1 gallon of 108 motor octane race gas to 4 gallons of 91 octane pump fuel.
3000’+: 91 octane pump fuel
Spark Plug Recommendation: BR9EYA
Important Note: Fuels containing ethanol, alcohol based fuel compounds, or oxygen carrying additives will require
larger main jets, usually 2 sizes more than the SLP jetting chart. Jet Needle may need to be raised one “E” clip position.
Also recommended is the use of SLP Torque Arm #23-57 to harness the torque load and eliminate clutch misalignment under acceleration. This reduction of engine movement in the chassis results in optimum clutch efficiency for maximum transfer of horsepower to the ground.
Also recommended is the use of an SLP High Flow Outside Draw Airbox Conversion Kit . This effectively transforms your stock intake system, allowing more cold air to reach the engine which translates into an increase in
horsepower. This system is also less likely to plug when riding in deep snow conditions.
