Brand: SuperTrapp Industries

This stainless steel 120 degree shield fits all 4" SuperTrapp Diffusers (Part Nos. ST-444-xxxx). It is designed to help protect the diffuser discs from damage and getting clogged by small rocks or dirt. It can also be used to block and redirect noise from one side.

Although this shield is designed for the "Diffuser Only" series (no glasspack), it can also be used with 18.5" SuperTrapp steel glasspack mufflers (Part Nos. ST-449-xx18). Because the body of these mufflers has a short 360 degree shroud, you must use a couple of diffuser discs as a spacer between the muffler and the shield. The shield will not fit inside the shroud portion of the muffler body.

Not for use with SuperTrapp stainless steel glasspack mufflers (Part Nos. ST-443-xx17 or ST-443-xx24). These mufflers already have a 120 degree shield incorporated into the body shell design.

Supertrapp 120 shield for 4inch diffuser


Does an exceptional job for what it is designed; silences a above 90 db exhaust to where it is enjoyable to drive; solved the problem of short exhaust/muffler run and gave me increased tuning of the engine. Have glass packed mufflers on a short exhaust piping run and now can drive the car with normal conversation level
