So I found a connecting pipe by supersprint that is "allegedly" bolt to the r56 and r57s. Question is, will it bolt up to a r57 JCW? Looking to get a bit more growl out of the tail pipe, and I always like the ability going to back stock using stock mounting points.

 

Well...to answer the question...it is not a bolt up. Would have to cut center pipe and weld rear and most likely front...so what's the point? Muffler shop can do that anyway. Don't know why no one makes a simply bolt up delete center pipe for these cars....
