I was looking at this on the BMR website, and it says that the unit isn't compatible with ASM headers. Anyone care to elaborate as to why, besides the website's claim that it's "due to the design of the motor mounts"????

 

I saw a post that mentioned a problem with A S & M headers, so I contacted BMR and the tech stated that there is interference with the K-member and collector & pipe on the left side. He also stated that there is no design change they can make to correct this. Let us know if you find a K-member that works.
