What our customers are saying:

"A big thank you for providing a quality product to help me convert an old Bosch CIS-E VW fuel system to -6an lines. I haven't found anyone else who makes them and they were the perfect thing to get my car running again. I'll probably be ordering more to convert my other cars and my friends' cars since we all have crusty old VWs that have obsolete NLA parts. I'll pass the word on about your parts. Thanks again."

SuperTrapp Universal Glasspack Mufflers

In general, larger and longer mufflers will result in less noise with minimal restriction on exhaust flow. These 4 inch disc mufflers can handle up to 250 HP or 4.0L (250 CID) per muffler. Dual or even quad mufflers can be used on much larger engines.
