I have it on.....mechanic promised me pics later of what he did, but I got a look inside. It sounds siiick. Lots of burbling and crackling without the drone. Sounds very nice when you rev the engine and very similar to a PE exhaust.

He took out all of the insulation and perforated piping, and removed the H pipe, so its basically a straight pipe setup running through the mufflers. For some reason, the addition of the muffler through the pipes eliminates the drone. FWIW, I do have my main cats on, with the secondaries deleted.

Video up later!
