So, I recently bought this '03 wrx... Still finding out what all was done to it. So far noticed a new pully on the engine, stealth bov, tien coilovers (yay!), and an as of yet unidentified turboback exhaust. I'd really like to figure out what it is so I can decide if it needs to be replaced or kept, sold... You get the idea!
So it has a plate on the muffler tip that says MT or MHT or MTT... not sure, its hard to make out. Also has a cursive performance written over it. The whole exhaust is stainless... pretty sturdy, as the previous owners lowered the car quite a bit and got the bottom all scraped up :/
Anyway, here is a pic of the muffler tip (didn't come out too well, stupid cameraphone. Well at least the gravel is in focus )
