Great suggestion! I like it a lot, I think I will change those bolts out to something a little nicer. Also, my m5 is lowered quite a bit on Dinan adjustable coil overs so it makes it even more difficult to see. I love your idea though! Consider it done! |

After having done catless downpipes myself, that alone added a little drone. I bought all the piping to do my own muffler delete, but I'm worried I'd be in the same boat as you. I've looked into doing electronic dumps like that as well, did some Google searches about pros and cons, brands that have higher success rates, BS warranty issues, etc. What brand did you end up going with? I'm suprised you put them that far back vs doing them before x-pipe.

As for the location...yes, that was a greatly debated topic. I decided to put them in the rear before the mufflers for 2 major reasons: 1. The smell. I knew I would be running them open 90% of the time. In traffic, or any stop and go situation I didn't want the exhaust to be right underneath me and any passengers. As I'm sure you know the smell with catless can be a bit much sometimes. 2. Drone. I wanted to minimize drone as much as possible and have a very comfortable highway ride (which I currently do even with the dumps open). After my last experience with drone; I wanted to minimize. |
