Is there anyone out there who has installed a header on a MINI used on the street. All of the venders selling headers have a disclaimer that they are for "off road" purposed and not street leagal. I think this is just a way of covering themselves. If anyone has installed a header, how did you get the cats to fit, and the computer from flagging a problem with the O2 sensors?
In general, they are sold as "off road only" because I don't think any of the headers have CARB numbers... as CARB gets touchy about modifying the exhaust between the head and the cat.
Some headers are better than others... some retain the pre-cat O2 sensor location better than others... some include a replacement high-flow cat - which is the only way I'd bother with one...
None will provide much benefit without head work as modern stock exhaust systems are already pretty good compared to cast iron manifolds vs headers on old V8's...
