Installation Tip: Use orange hi-temp silicone on all connections for tighter and quieter seal of components.

1. 1 3/8” or 1 ½” Outlet

– The first step is to determine what is necessary to make the outlet on your ATV

exhaust have the 1 3/8” O.D. or 1 ½” O.D. male outlet needed to adapt to the Stealth Exhaust 2.0. For ATV’s
that have a male outlet, use the Adapter Bushings (12, 13, or 14 in BOM) in the kit (see instruction supplement)
to bush it up to the 1 ½” size. If your OEM outlet points down, you may need to cut it so it points more directly
out the rear of the machine. Be sure to leave the outlet long enough (at least 1 ½”) to slide the bushings on it
and attach the Stealth Exhaust 2.0. If you are mounting the Stealth Exhaust 2.0 directly to the existing outlet on
your ATV (as in the pictures of the Yamaha Grizzly), use the smaller 1 3/8” muffler clamp for this connection.
Also, use the high temp silicone (not included) for this type of attachment.

For ATV’s (such as Honda) with no male outlet –

Use the weld on adapters (10, or 11) See the

instruction supplement.
DIRECT MOUNT: Weld on the 1 3/8” O.D. adapter, and install the Stealth Exhaust directly over the adapter,
and clamp it with 1 3/8” Muffler Clamp.
HIGH MOUNT USING ELBOW ADAPTER. Weld on 1 ½” O.D. adapter; then the adapter elbow will slide
over the weld on adapter. Now clamp that using the 1 ½” muffler clamp. Hold the proper adapter centered over
the outlet and weld it in place. Wire feed or any type of light metal welding works well for this. If your OEM
muffler is stainless steel, generally Type 309 wire or rod works best. If you do not have welding capabilities,
most welding shops will do it for a minimal fee. It is suggested you disconnect the battery, and put the welding
ground as close as possible to the weld area to prevent any damage to the ATV’s electrical system. You can
also remove your muffler to weld on the adapter. Weld on adapters can be used to adapt most any ATV to the
Stealth Exhaust 2.0.
BOLT ON ADAPTERS 53520: A universal bolt on adapter is available for many applications, such as the
Honda Rancher 300, the Forman 400 and 450, or any ATV with a flat or concave outlet on the OEM muffler.
There are bolt on Adapters available specifically for the Honda Rubicon (53530) or the Suzuki Vinson (53535
2003 or Older only).

2. Mount Muffler –

Determine how and where you want to mount your Stealth Exhaust 2.0 and install it

using the rubber coated mounting clamps and the Mounting Bands (2) in the kit. Select the proper rubber
coated clamps, (there are three sizes, 8, 9, or 10 depending on your rack Diameter), for the frame or rear rack on
your ATV and slide the clamp over the over that. Then install the Mounting Bands (2) over the muffler using
the supplied Bolts and Nuts (15, 16, and 17) and hang it in place, using the 8 holed Mounting Strap (4), which
you can bend, cut or drill to better accommodate your needs for your application. Hang the Stealth Exhaust2.0
in place, but do not tighten at this point.

3. 80 Degree Adapter Elbow Connection(3) –

Hold the special adapter elbow in place, between the

ATV’s muffler outlet and the Stealth Exhaust inlet. Determine where to cut the adapter elbow to fit.

CAREFULL NOT TO CUT THE ADAPTER TO SHORT!

Cut the adapter to fit with a hack saw. Do not

distort the tube by clamping it to tight in the vice. Be sure to clean the burs from the cut end with a file or some
sandpaper. This will also allow it to slide on easily. To assemble the elbow into place, you will have to loosen
the muffler hanger or take the muffler back off. The next step is to put the adapter in place and make sure it fits
correctly. Attach it using the 1 ½” clamps form the kit. Again, you can use some orange hi-temp sealant on this
connection. Now, reassemble your muffler and hangers into place and tighten all mounts and clamps.

Direct Mount –

If your ATV already has a male outlet, simply slide the supplied bushings on your ATV

outlet and install the Stealth Exhaust directly on it using the smaller 1 3/8” muffler clamp. (See Grizzly
Pictures). For a direct mount to the rear of the ATV’s muffler with the installed 1 3/8” weld on outlet, use the
1 3/8” muffler clamp. You can use some high temp silicone on this connection and on the bushings.
