KwS 2169 Report post Posted June 26 3 hours ago, Eagle said: The few dyno's videos etc ive seen seems to confirm that no difference, they beat on them on hard in one video. Primary tubing generally being oversized and gases flowing faster in the middle of tube and slower on outside was the reasoning. Im sure Engine Masters did it at one point and ended up with SFA difference. I'd hit that. 1 Quote Share this post Link to post Share on other sites
Jacko 1795 Report post Posted June 26 Im leaning towards giving the mount a trim, heaps of meat below the lip and it looks to clear the stud still. Also have a spare mount Should be able to reattach the heat shield with some panel beating. Quote Share this post Link to post Share on other sites

GorGasm 474 Report post Posted June 27 Yeah I remember a TV show where they mangled the headers and dynoed the same or better. In the case of my E55 one of the pipes needed a bash to clear the steering column. Probably dropped from 500hp to 499hp or something. Thing was making like 800NM so I was far too busy managing traction to notice any power difference. 1 Quote Share this post Link to post Share on other sites
Jacko 1795 Report post Posted June 29 Few swipes with a file, will need a few more once I've beaten the heat shield into a new shape. 1 1 Quote Share this post Link to post Share on other sites
