In my M3, every ten pounds I lost changed my power:weight as much as gaining 1 hp did. Made those taco bell runs mean more.

It does look neat. I just think it's amusing that on one side of the N/A section, you have guys who are happy about gaining a hundredth of a second on a 60-90 pull, a very small percentage increase, guys talking about porting throttle bodies out .5mm all around, and on the other end you have folks who do a 335 exhaust mod like this, gain 10 pounds hanging out past the axle and lose 2 hp in restriction. I feel like I'm somewhere in between.
