Hey, All -

This question gets asked all the time, but if it makes it any better, I already searched through the forums in an attempt to gather as much info as possible before asking....

Now that everyone with aftermarket exhausts has run them for 5-10k+ miles and the sound has changed, what's the consensus on the most aggressive sounding system available for the X5M?

Contingencies are as follows:
- Down pipes aren't an option
- System must be valved for when the baby is in tow.
- Not concerned with decibel per dollar value. Just the decibels...

I've watched all the videos and it's difficult to make an apples to apples b/c some vids are filmed on a dyno and those sound terrible. Some are filmed outside, and others are filmed in warehouses aka giant sound chambers...

Thanks in advance.
