53550 Stealth Exhaust 2.0
Supplemental Instructions for the Weld on Adapter and the Adapter Bushings.
SPLIT TYPE ADAPTER BUSHINGS – The three (3) split type adapter bushings are designed to be used
together in steps to bush the existing outlet on your ATV’s muffler to the proper size, to accommodate the Kolpin
Stealth Exhaust 2.0. The bushings can be gently expanded or squeezed together to make installation easier. The
bushings are identified by part numbers as follows:
1. 57 – 1 1/8” to 1 ¼”
2. 58 – 1 ¼” to 1 3/8”
3. 59 – 1 3/8” to 1 ½”
To achieve the proper installation and seal without damaging the stealth muffler inlet, the bushings must be used in
these steps, per the above example.
Models with 1 1/8” O.D. male outlet, such as Yamaha Grizzly.
1. First install the number 57 bushing that goes from 1 1/8” to 1 ¼” on the OEM muffler outlet.
2. Next, over the number 57 bushing install the number 58 bushing. This will take it from 1 ¼” to 1 3/8”.
3. If you are direct mounting the stealth muffler, you now have the proper 1 3/8” O.D. outlet needed on
your ATV to install the Kolpin Stealth Exhaust 2.0. Simply clamp it down using the muffler clamp
provided. For a maximum seal, use orange hi-temp silicone on the bushings and any connection points.
4. If you are using the adapter elbow to connect the Stealth Exhaust 2.0 to your ATV’s muffler such as for
a mid or high mount, you will have to us the third bushing, number 59. This bushing goes from 1 3/8”
to 1 ½”. You will now have the proper size, 1 ½” O.D., to us the elbow adapter and clamp it down over
the bushing assembly and connect it to the Stealth Exhaust 2.0
Models with 1 ¼” O.D. male outlet, such as the Sportsman series.
1. First, install the number 58 bushing that goes from 1 ¼” to 1 3/8” on stock muffler outlet.
2. If you are direct mounting the Stealth Exhaust 2.0, you now have the proper 1 3/8” O.D.
outlet on you ATV to correctly install the Stealth Exhaust 2.0. Clamp it down with the 1 3/8” muffler
clamp. For the best seal, use orange hi-temp silicone on the bushing and connections.
3. If you are using the adapter elbow to connect the Stealth Exhaust 2.0 to your ATV’s muffler (such as
mid or high mount), you will have to use a second bushing. Use the number 59 bushing that goes from
1 3/8” to 1 ½”, and slide it over the other bushing. You will then have the proper size, 1 ½” O.D., to use
the elbow adapter and clamp it down over the bushing assembly and connect it to the Stealth Exhaust
2.0
WELD ON ADAPTERS (10, or 11) – There are two weld on adapters in this kit, they should be used as
follows.
1. If you are direct mounting the Stealth Exhaust 2.0 use the smaller 1 3/8” O.D. x 2” Long Adapter. After
welding this adapter on, you will have the proper 1 3/8” O.D. size to direct mount the Stealth Exhaust
2.0. If you decide later to use the elbow adapter to connect your muffler, you can slide the number 59
busing on to the weld on adapter, and this will give you the 1 ½” O.D. size to use the elbow adapter.
2. If you are using the elbow adapter to connect your Stealth Exhaust 2.0, (such as mid or high mount), use
the larger 1 ½” size to use the elbow adapter. Again, for the best seal, use hi-temp orange silicone on
connections for the best result.
WELDING SUGGESTIONS: If your ATV’s stock muffler is stainless steel (Such as most Hondas), type 309
welding wire or rod for dissimilar metals is recommended and may produce a better weld. This is a
common welding material at welding shops.
