LOL - 6 out of the 8 pictures show an E70 X5 on the ad for this cheap little muffler.

Sobi...I've seen guys in 530's try to install the same Magnaflow 14815/14816's that we M5/540/740/750 guys have used, only to have it drone like mad on the I6's because of the decreased engine size. Anything you put on your I6 will have completely different results than it would have on the V8. The only way you're going to be able to search around for exhausts is to either look here or on the other bimmer boards and make sure you're looking at I6 specific threads. On my 7 I removed the resonator and replaced it w/ an x-pipe and the Mag mufflers...sounded like complete ass. After countless threads, it's either the V8 guys do the x-pipe or the mufflers, but not both (Magnaflow specific, I can't say for those who used $$Dinan$$, etc). Since you've already got tips, and I don't know if the I6 X5's even have an x-pipe (I don't see how they could based on the engine design), you're better of searching around for what's already been done and go from there.
