I look inside the exhaust housing and it says 48, that means it is a .48 AR right? I was supposed to get a .63 AR.

 

where did u order it from?

 

It came with my f-max kit.

 

F-Max recommends .48 A/R for B18B's. Unless you've specified otherwise, it's what is supposed to come with the kit. I would stick with it.. but that's just my opinion.

 

this is for a h22a not a b18, i should have the 63.

 

Hmm.. my friend got a stage3/.63 T04B H-trim with his FMAX kit for his 95 Prelude Si H23A

You can give it try tho. I doubt you will be disappointed. That will be one fast spoolin ****. Unless you are all about top-end, keep it.

 

send it back and get a .63 u not going to like it i had a .48 on my h23 i had one and i sold it in two weeks after i put it on not much top end in a .48 i had a shift at about 6500rpms now i shift at 7800-8000 and still making power with a h23 and i got a .63
