Thread: O2 housing advise needed

I have been thinking of what O2 housing to get for my turbo set up and i can't decide which is a better choice. Looking at getting to TurboFx o2 housing but can't decide which is a better choice, the recirculated or the screamer. Also is there a performance difference between the two? Is the screamer too loud to drive on the streets without getting the attention of the local PD? Any insight will help,thanks guys

I did quite a bit of reading about this subject before deciding on the bellmouth.

Everything I've read regarding the divorced option is that the screamer pipe is pretty loud. I guess that's 'relative' to what you consider loud. I've read some people getting the screamer pipe re-welded into the downpipe. I've also read of people extending the screamer pipe under the car and installing a small muffler onto it for sound deadening.

I chose bellmouth because Javier(turbofx) needs your exhaust housing so he can completely seal it from the wastegate opening(a good and proper thing to do..I'm just impatient) and I didn't want to mess with the screamer pipe.

Regarding performance difference, no one has yet to dyno a before/after with these so can't say for sure but you should see gains with either housing over the stock housing. You should see better gains w/the divorced housing.

i have a screamer and its not as loud as you would think. only loud when your romping it. i think i would like to eventually get it recirculated though.

LOL that "screamer" pipe is the exact same sound that an External wastegate would have. Its not loud and the sound is heaven on a 38mm. Anyone who thinks its loud is old

you have a screamer jpipe on your fwd de+t ?

stratton.

i think you need to get back into the boost game.

Thanks for all the input guys

I 2nd that screamer pipes are not loud

I have a divorced 38mm Tial and unless I am well into boost, the wastegate does not open = not loud.

Once it opens up it is still not as loud as people would think.
