Just had a twin dump downpipe fitted...
The sound is a lot more sharper, more of a growl now than a meow, it does pop quite nicely, but, it's the performance that makes the difference, so so nice 
They say when you drive an Impreza you smile, drive one with a twin dump downpipe, you grin inanely

i've just had one fitted myself from midland impreza and all i can say is what you did, "why not earlier".
i love it. you can hear the turbo spinning up through it and when decelarating. it pops and bangs more often and louder and the performance!!

Apparently a twin-dump pipe gives you better torque at low revs, but an open-neck (e.g. Scoobysport's d/p) will give better power at the top end. I can't compare, tbh... I've only ever had the SS 'open' pipe fitted since removing the original.

I have a scoobysport DP fitted at the moment and it is great but what are the benefits of a twin dump one over the one I currently have.
