The pipes didn't work well enough to pass sound - 92dB was the limit and I was hitting 94-95 dB. The supertrapps were more effective but I still have to lift when going by the sound station. My car without either is at about 98dB wide open.

Pipes installed - 3" diameter

Supertrapps
That looks sweet with the Supertrapps sticking out like that!
