Downpipe and exhaust questions
So I have a t3/t4 turbo set up on my focus, I want to upgrade to a 3 inch downpipe from topspeed. Along with that downpipe I also want to get one of their racing manifold. Both of these are v-band style inlets. Would a v-band turbine housing be the same as a t3 housing if their are the same a/r? or different a/r?
Also I want to upgrade my exhaust as well. I have the hks catback on for the moment, but find it to be a bit to ricy. looking for an exhaust thats essentially low in volume at low rpms and louder going up (I know this is the usual case) also looking for it to be 3inch all the way out the back.
Basically my build is trying to create a 400hp sleeper, so I need to squeeze all the extra hp out of anything I can.
