Find me a guy with a 4.6is who wouldn't love to drop these in and Sa-moke a 4.8is next time they had a chance.
I'm planning on some forced air down the line so opening up the flow on the back end is a real treat.
As far as cramped space, if you took a lunch break to read that whole thing, it's all modular, shouldn't be difficult at all for the e53. One custom weld if you're keeping cats and a steep downward bend for the secondary collector.

For the price... I think FI is attainable and the gains much greater. And I'm curious if the 5spd vs. the 6spd trans would still have the 4.8is be neck and neck? An S62 with ITB's and other improvements over an M62 is going to benefit more from these and the HP gains are going to be much more modest on the non-M engine.
Again, not saying these aren't worth $5500 or taking anything away from the work done. Being able to install these without dropping the subframe is a huge plus as well. I'd just be very surprised if someone with a 4.4 or 4.6 would want to do these vs. a Vortech.
