Regardless, with piggybacks there is a fine balance with what it possible to attain. That 40-50 HP range on the early M550i is about the limit in our eyes without getting into the realm of consistent issues (setting CELs) with fringe cars that may be closer to the edge of factory tolerances or the need for outside influences (whether that be race gas / ethanol mixes or additional hard parts). If you look at the competing landscape (in-line/piggybacks specifically) everyone is about the same in terms of performance when you take out those tertiary variables. Now if you want to play with fuel mixes and/or custom tune with some additional hard parts with an in-line that is the domain of the JB4. They do it well and for some that is enjoyable. But that also introduces a lot of variance (and emissions complications) which will cause some additional haeartache. Our goal has always been to offer a solution that causes the least amount of heartache and can be set and forgot about if desired.
Thanks for the comprehensive reply, just so you know I have a ton of Dinan products on my car and am a big fan. Close to ordering the full axle-back and mid pipe, so if you are going to come out with an "X" version of that soon for half the price, let me know! Kidding.

I just looked at my receipt from my Dinan shop. You are right, it was $1,803.95 plus tax and $130 to install.
