I'm looking to purchase a new manifold (likely RNR) and an O2 housing that will work with my 2.75" Tanabe downpipe.

Any suggestions for an O2 housing? I am uncertain if many of the 3" O2 housings on the market will work in this situation.

Thanks.

 

Hi,

I am using the Helix O2 housing with my Tanabe 2.75" dp. The spool up was better after installing the Helix O2 housing.

We have one Helix O2 housing in stock if you are interested.

My last dyno number was 290whp on my Mustang Dyno with CA 91 octane. Just for a reference, a stock Evo is around 210-215whp.

Thanks,
Tom
