Re: 0331 to 0630 Swap Kit

Yes - I'm still selling this plate! Maybe I should learn how to make a website for this thing?

Regarding performance: There honestly seems to be no noticeable loss in performance. Think about this - the clearance holes in this plate are pretty much the same size as your stock exhaust.
So unless you are replacing your stock headers for something that matches the 0630 ports (in which case you would definitely not be interested in the plate anyway) then this plate is not your limiting factor - it's your exhaust. I get this question a lot.
'01 XJ, Limited - Stocker (w/ 0630 head)
'89 SJ - 8" SOA, 36" IROKs, High-Steering, Rear Discs, NP208 swap + other junk.
'90 XJ - RIP - 3" lift, 31's (dead, buried, but not forgotten)
