thats how mine will be. no cat with a muffler you can see through and an electric cutout later

 

Technical definition would be nozzle . I'm sure it will work but in my opinion will be sub-optimal. If you're building from scratch why not go 3.5-4" single?

Got details of your setup?

ok. heres my reasoning. i had like 20 turbo dsm cars, no exageration. 3" was waayy more than needed on them, and i know that they were 4 cylinder cars, however, my mpt70 turbo has a 3.25" outlet on it and the car currently has a 3" exhaust on it with no problems at all, so it seems to me like a 3" exhaust with this small of a turbo should be fine. if later i upgrade to a t88 or something like that then ill ill sell my setup and upgrade my exhaust, but until then i think it'll be ok as long as its pretty much straight through. if not ill let everybody know, and eat my words later

 

cool man. I think it will work.

-Scott.

 

i hope so, but i am pretty sure itll be fine

 

Not the best because you can't judge volume from a handheld and youtube but...

Idle - You can see where my turbo is. My downpipe basically makes it to about the drivers seat and dumps. 3" - I had a 3" Sweet thunder muffler on it which is stright through other than the d hammer baffles and could not make more than 10psi.

The whistle is farrrr louder than the motor. Granted a muffler would drown some of that out I really like the way it worked out. At idle its not much louder than an 80 series flowmaster. At WOT it sounds like a jet.

 

im gonna be running a dumped 5'' DP

 

If you actually have a turbo with an outlet big enough to justify that, I bet its going to be loud.
