Shell Valley Stainless Steel Side Pipes

  • The first thing that will capture your attention is the Ultra Shine finish on the GASN side pipes. You will immediately notice the high luster and the attention to detail, the quality is outstanding.

    The sound has been adjusted to be quieter than the side pipes offered by the manufacturer. This adjustment is made by using a flow-through muffler design so horse power and torque will not be negatively affected.

    They can be special ordered with a 3” flow through core muffler for high horsepower cars.

    The merge collectors use race inspired technology and are built with scavenger spikes for better flow and sound. We use a ceramic blanket packing and 304 stainless steel wool in the muffler to add to the sound quality. We do not use fiberglass packing.

    We pride ourselves on providing customers with the best-quality products and personal service. You can order by phone or on line. My name is Georgie and I am happy to take your call!
