Hi friends,Which o2 housing or turbo outlet has the good specs and would recommended to replace the factory unit. IŽll use the car in off-road competition

Thanks in advance.

 

I am buying this one because of the good quality material used and quality of welding. Im not sure what the specs are but the external dump will make it have less exhaust to go through the system.

Thank you Brent,will look at it

 

just bought a mr o2 pipe but had to get it ported and polished a lot of roughness inside.

 

Search theres plenty info

 

do you want to dump or are you just looking for more flow?

 

Just looking for more flow,so will have quicker response at lower RPM

 

A 3" outlet would be your best bet performance wise, but a highflow aftermerket unit can be had for $45 to your doorstep on Ebay. Many people use these with great success on the dyno.

 

Here are a couple of the most popular options:

Megan Racing $109.99 Shipped
MAP O2 Housing $174.99 Shipped *11% rebate via gift certificate, use discount code 2011Rebate*
MAP External Dump O2 Housing $329.99 Shipped

 

Im sure one with an open dump would provide a little more power, not to sure about response. I might have to look into it. It also sounds insane on full boost.

 

The MAP O2 parts are some very nice stuff indeed. My favorite vendor by far.

The dump housings will reduce restriction at full boost, but won't affect low-rpm response as the air won't by flowing out of both ports.

Here's the type which many people use:

I'd steer clear of the gasket they use, get an OEM one instead.

 

CONFIRM.

Ebay is winner here per price+perfomance.
