How to Install Dual Exhaust Systems

Dual exhaust systems let your engine run cooler, decreasing the inherent back pressure and increasing horsepower for better performance. As the exhaust exits the car more freely, you will notice faster acceleration, stronger passing power and a terrific sound. As long as the muffler and pipes in the exhaust system are installed properly, your car will almost feel brand new.

Instructions

    1

    Select parts that are sized properly for your car. Higher-quality exhaust systems take advantage of mandrel-bent pipes and mimic the look of the original car parts. Your local auto shop may build custom dual exhaust systems, but they are probably created with generic parts and fit poorly.

    2

    Pick a kit that includes all clamps, hangers and hardware, so you will not be searching for pieces to complete the installation.

    3

    Stop blowing gaskets by using a steel donut gasket when connecting the manifold. The steel resists heat better than other gaskets, while sealing the pipe and manifold together.

    4

    Position exhaust pipes to clear both the floorpan and the driveshaft by at least 1 inch. When finalizing the setting, remember that the shaft moves up and down with rear axle, and the pipes must clear it completely.

    5

    Use factory muffler positioning to make most exhaust systems a simple bolt-on installation. If you place your muffler differently, the pipes may need to be bent accordingly. Hanging mufflers higher may require you to drill into the floorpan to hang them.

    6

    Mount tailpipe hangers near the frame rail to prevent the pipes from noticeably rattling. Brackets should face the front of the car in most cases. Your exhaust kit should come with the proper hangers, but you may have to have a few self-tapping bolts on hand.

    7

    Check the clearance before completely tightening all bolts. Things move as you attach other parts, so make sure there is still a 1-inch clearance. Rotate the rear axle to make sure the driveshaft doesnt rub against the muffler.
