Hey everyone,

I've recently purchased a 02 STI and the exhaust is too loud for me. The mufflers are branded Super Cat (see Super Cat) so I assume the exhaust came from them too. Not being a named brand I don't know anything about them, It is 3" and mandrel bent but would the dump-pipe be any good? On my previous WRX I went for a MMS 3" Stainless TBE and was more than happy with the performance, note and loudness.

What are all the extra cat-looking things? My previous exhaust only had the hi-flow cat and the muffler. I thought one might be a hot-dog, this made me sad.

I was just hoping for some advice on what to do to quieten down the exhaust, I don't really want to replace the entire thing but will do it if there are performance gains to be had. Also, I still have the full STI TBE exhaust, could I use any part of it? It would be loud enough for me but I don't know whether the muffler would fit onto the 3" piping.
