I purchased another stock xpipe off someone because I did not want to cut mine, then I had a custom test pipe welded to the xpipe. I like this setup better than an aftermarket xpipe because you still retain the secondary cats that do not restrict power, the exhaust smell is toned down alot in my opinion when compared to another M3 with aftermarket xpipe with cat delete and you save money, most xpipes are over $1000 not worth it there are no power gains from an xpipe.
