No idea what sort it is, I just know its's damn loud!

I've had quite a few WRX's and STi's in the past, majority with 3 inch TBE and none including my old track car have never been this loud..

Maybe four years without a rex has made my ears more sensitive? Either that or the old age thing is kicking in.

I pick the car up from Rockingham on Saturday, I'll suss out what the exhaust is then and report back.
