Well...I had plans on modding my 540i, but in the end I just decided to let BMW do the modding for me...For Now, Borla Exhaust is sitting on my garage floor.

I haven't updated this page for a while. I have just been enjoying this BEAST! I finally put my exhaust on in June of 06, and lost about 70lb. from the car! Holy COW is that stock exhaust heavy! The Borla system is VERY well made and I got it for a steal. BMW snobs usually overlook this system but it is really nice for the price. Plus, it is a TRUE cat back system, it replaces the x pipe with a MUCH larger pipe. Butt-o-meter says that I picked up some power, but I am too lazy to get it dyno'd. I will be needing a clutch upgrade soon, so I might just get the SS headers/Downpipes and the AA cold air intake kit. It "Should" be pushing 450hp by then. I will definately dyno it after those mods are done.
