why dump to the atmosphere

[DeezNutsForYou]

I have a 92 gsx and I'm looking into a 3inch turbo back exhaust. I have seen a few downpipes that have an O2 eleminator which dumps to the open air. I was wondering if anyone has this and how much does it help. Does it sound like ####, and does it do anything to help boost creep.
Thanks for the help
One more thing has anyone welded there own exhaust and how hard is that, is it worth it. (time/effort/money)
thanks again

It will help with boost creep if your wastegate is big enough.

Yes, it does sound like ####.

Some people love the sound of the O2 dump some hate it. There was a thread on here a few months ago where we argued over it. I personally don't like it as it just draws way to much attention to your car when your doing the very thing you shouldn't be (speeding + loud open exhaust = problems with cops)

I'm into the 100% lagit setup where cops pull you over just dieing to give you a ticket and your setup is so lagit they can only admire under you hood and feel like a loser for pulling you over

There is a performance gain from it as well. On a H22 we did a turbo kit and it started as atmospheric and eventually the guy didn't like it so we put it back in and he lost 2/10's from a low 13 second 1/4 mile time. We figured about 10hp from re-routing it back in. It even felt slower on the butt dyno too right after we finished the work and went out for a drive. It was wierd.

Its only loud when you get in the throtle, but you get used to it. Just like you get used to a walbro. Fast cars werent meant to be quiet

how loud, and what exactly does it sound like?
