SuperTrapp Diffuser Only Series
The SuperTrapp Diffuser Only series give you the tuneability of a SuperTrapp muffler without the added weight and bulk of a glasspack muffler. Simply weld the flange to your exhaust pipe and install the diffuser discs and end cap.
These diffuser assemblies offer much less sound reduction than SuperTrapp glasspack mufflers. They are ideal for use after an in-line muffler.
The 4 Inch Diffuser Only kits (Part Nos. ST-444-xx03) include a weld-on mounting flange, end cap, 12 diffuser discs, and disc hardware.
The 5 Inch Diffuser Only kits (Part Nos. ST-554-xx03) include a weld-on mounting flange, 360 degree shield, end cap, 12 diffuser discs, and disc hardware.
The Adapter Flanges (Part Nos. ST-407-xx00 and ST-507-xx00) are replacements for the mounting flanges included with the Diffuser Only Series kits. They do not include hardware, endcaps, or diffuser discs.
