The patented radial diffuser design of SuperTrapp mufflers allow you to tune your muffler by adding or removing diffuser discs. Fewer discs result in a quieter system with more backpressure, while more disks increases noise and lowers back pressure. You can gain a measureable performance advantage by wave tuning your engine and carburetion to produce the best power band for any track. In certain racing classes where carb tuning is restricted, the SuperTrapp has become standard equipment. Many race teams have also equipped their tow vehicles with SuperTrapps and in almost every case this has improved gas mileage and performance while helping to reduce detonation.
To mount these to your exhaust system, just weld the furnished adapter to your tail pipe and then bolt the discs and end cap to the adapter. Comes complete with 12 diffuser discs.
