How big is it? i heard 00silverLS say that his dp from f-max is only 2.25...i'm hoping the H22A dp is at least 2.5"....someone plz tell me...thx

oh, another thing, i'm thinking about getting the turbo housing/manifold/dp thermocoated.....is it worth it?

 

i thought it was 2.5 also...thats what rich said. still havent gotten around to callin fmax

 

I am going to get mine coated from HP coatings. I have heard it is good, but I am doing it for the looks. It is supposed to lower the heat generated under the hood and spool up the turbo faster. Not to mention the parts will last longer!

 

I do not see how it can be 2.25. The outlet from the turbo is 2.5".

i was thinking of going with jet-hot....98lude got his stuff coated there and it looks great....who's better? any thoughts?

 

I never really measured it. I assumed it's 2.5". It looks like 2.5". I haven't seen my car in 3 weeks so I can't look at it now. I have a 2.5" exhaust, it looks like the same diameter.

 

The Lude kit is different for the integra kit. All I know is the downpipe for my kit, for the b18b, is 2.25". I'm pretty sure the Prelude kit has a 2.5" downpipe, but I'm not at all sure. If you really wanna know, call F-Max.
