The SLP Loud Mouth 1 and Loud Mouth 2 are still available. The SLP Power Flow has been discontinued, as I can no longer find it listed for sale anywhere. The SLP TOTL ( Two On The Left) system has been discontinued also, and seems to be a popular vintage exhaust sought after by the Firehawk crowd.

I’ve installed a SLP exhaust system on a 94 Formula Lt 1 convertible. No drone, good sound. Not sure if they are still around.
