I have a 3" Stromung single-tip catback mated up to the stock 3rd cat on my 06 STi. It's just teetering on being too loud so I'm considering trading it for something quieter. Looking to see what people have that might be interested in trading. Some exhausts I'm considering are the SPT, Prodrive (axleback), Tanabe Touring Medallion or Concept G, any Fujitsubo exhaust, or MadDad Whisper. It must fit the stock donut gasket.

I'll trade you my stock exhaust for it.

Hey, it's quieter! :D

I'll trade you my stock rsPRO exhaust + $$
