Product Usage Instructions

1. Begin by placing the vehicle on a lift or four jack stands at maximum height to aid in an easier installation.
2. To help ease the installation, pre-fit all the components into a complete system on your garage floor, using the diagram provided.
3. First, remove the existing exhaust system from the headers or exhaust manifolds back. You can also remove any hanger mounted to the frame as your new kit includes factory reproduction hangers.
4. Now, install your new components. Begin by test installing your new side exit tailpipes. These tailpipes are designed to run inside the rear trailing arms. Since this system uses universal style hangers, you will need to determine the approximate location to mount them. The tailpipe hangers will mount to the outside of the frame rails just behind the rear tires. The muffler hangers will get mounted to the mid cross-member where the trailing arms are attached. If you so choose, custom hangers may be fabricated, let your creativity shine.
5. Now, install the mufflers. The mufflers in the kit are designed to mount vertically with the logos facing left to right. The center outlet will get connected to the beginning of the tailpipes. The clamp attached to the hanger at the front side of the muffler will be the only connection clamp used.
6. Finish the system by making all your final adjustments to position the mufflers and piping. Now tighten all the clamps or for the best fit weld all the slip joints. The stainless steel can be welded with your standard MIG welder.

Note: Always follow safety precautions and consult a professional if needed when installing or modifying exhaust systems.

Installation Instructions

1. Begin by placing the vehicle on a lift or four jack stands at maximum height to aid in an easier installation. To help ease the installation, pre-fit all the components into a complete system on your garage floor, using the diagram provided.
2. First, remove the existing exhaust system from the headers or exhaust manifolds back. You can also remove any hanger mounted to the frame as your new kit includes factory reproduction hangers.
3. Now, install your new components. Begin by test installing your new side exit tailpipes. These tailpipes are de­ signed to run inside the rear trailing arms. Since this system uses universal style hangers, you will need to deter­ mine the approximate location to mount them. The tailpipe hangers will mount to the outside of the frame rails just behind the rear tires. The muffler hangers will get mounted to the mid cross-member where the trailing arms are attached. If you so choose, custom hangers may be fabricated, let your creativity shine.
4. Now, install the mufflers. The mufflers in the kit are designed to mount vertically with the logos facing left to right. The center outlet will get connected to the beginning of the tailpipes. The clamp attached to the hanger at the front side of the muffler will be the only connection clamp used.
5. Next, install the h-pipe. This is where trimming of the tubing may be required for the optimum fit. Install the rear legs into the mufflers first. You are aiming to have the center “H” and approx. 12-16 inches behind the tail shaft of your transmission and centered under the driveshaft. Also, the center plate on the “H” has an arrow H stamp which must point forward. Trim the rear legs as needed to put your “H” and mufflers in the proper location. Quick tip: If the rear suspension is unloaded, you can push the center “H” up until it just about touches the drive shaft as it will never hit once the suspension is loaded. Slide the front legs into the h-pipe. They should end member. On some applications, the front “H” legs may not be centered in the humps but line up to your headers or downpipes. This is fine as the system will not hang too low. Be extra careful when measuring and cutting. A helpful tip: Line up the front legs under the center “H” to mark your cut lines making sure to line them up with you headers or downpipes.
6. Continue by connecting the front legs of the h-pipe to the headers (collector/reducers) utilizing the two 1ft collector extension pipes. Trimming the length will be required. Do not connect the h-pipe directly your headers. If downpipes (see downpipe instructions) are used, make sure the pipe ends close to the rear side of the trans­ mission crossmember. If they are too long they must be trimmed. Some header applications require custom col­ lectors due to the header not ending square and parallel to the car. For proper system fit, you collectors must run parallel with your rocker panels.
7. Finish the system by making all your final adjustments to position the mufflers and piping. Now tighten all the clamps or for the best fit weld all the slip joints . The stainless steel can be welded with your standard mig welder.
