I have a jdm sti 03 and as it has a twin scroll turbo with equal length headers it doesnt have that burble sound which i loved about subarus in the first place what downpipe do i need including exhaust as a full decat what do i need to be looking for newbie to the scene cheers rick

 

RCM do 3" twin scroll systems.

Powerstation do 3" twin scroll systems.

Scoobysport also do 3" twin scroll systems I think.

 

I have a full turbo back de-cat H&S system on my 04 STi JDM, great exhaust but i'm going bigger will have it up for sale soon. PM me if your interested

 

It wont burble it will howl like a japanese superbike if you uprate exhaust!

 

As Rick says, they wont burble, but thats not a down side they actually sound better than those with the uneven length headers
