I've noticed that most if not all people running an external wastegate have their dump tube connect to their exhaust somewhere under or between the engine and firewall. Any reason why? Couldn't you just connect the dump tube let's say 1 ft. after the exhaust flange from the turbo?

alot of people state that turbulence or some ---- (from the sudden purge of exhaust gases from the wastegate) will disturb the flow of the exhaust and hinder performance.they say that routing the tube farther back into the down pipe/exhaust will remedy this. some do it, but others just dump it.

"Just dump it" It's been said that by "dumping it" it's loud, not what i want, but thanks for the input!

If your going to coonect it back into the downpipe, make it ATLEAST 12" downstream form the turbo, optimal is 18"

And make it a nice gradual flow in, no 90* bullshit

Noticed your fairly local to me in the GTA to

Why do you care about noise when the dump is open? It is only making noise when youre boosting, and it sounds sick

A lot more power, and personally, a better noise and less fabrication with an open dumptube

I have read on this forum, not to long ago, depending on you're setup, some sound good, others sound like total ----. I guess i could fabricate my dump tube to eventually connect with the rest of the exhaust pending on how loud or shitty it sounds.

its all about horsepower man, you wana quiet turbo ride, go by a stock turbo car. i have open dump in my car, it screams when it opens up.

you can connect it wherever you want to the down pipe

if you want to run open dump tube and and still remain quiet, you could try putting a resonator or small muffler on it.( that would be gay)

personally i like the sound of a short open dumptube.

the only time your gonna hear the exhaust from the dump-tube is when you got it wide open throttle.. other than that your not gonna hear it.
