SuperTrapp 18.5" Long Mufflers
In general, larger and longer mufflers will result in less noise with minimal restriction on exhaust flow. These 18 1/2" mufflers are among the shortest full-size glasspacks SuperTrapp offers. They offer a good balance between small size and low noise.
SuperTrapp mufflers with 4 inch diffuser discs can handle up to 250 HP or 4.0L (250 CID) per muffler. The 5 inch disc mufflers can handle up to 400 HP or 5.7L (350 CID) per muffler. Dual or even quad mufflers can be used on much larger engines.
