This is amazing. Win I win the lottery I'd love to do this with my 3.0i. Once it's completed hopefully you start a youtube channel and do a full walk around and dyno. Great work.

Downpipe looks great. I vote keep the iS exhaust.

IS exhaust will compromise performance---too much back pressure.

Hotside is done. On to the intercooler and charge pipes. Picked up a low mileage rear differential out of a 2008 BMW M5 with a 3.62 LSD and the factory M5 rear axles. The cases seem very similar outside of the car and we will be finding a way to get that to work in the back of the SAV as well beefing up any weak structural parts of the rear subframe so we don't have any tears. If the M5 diff is a direct bolt it would make the perfect gearing upgrade for any future DIY LSX X5 swappers.















Also in reference to the exhaust we thought about using ECS Tunings 3" Vacuum Exhaust Cut-Outs right before the 4.6is mufflers with custom piping to the cutouts and make it so that once the X5 gets into boost it opens the valve to cause no power restriction but around town out of boost it will have to go through the mufflers. We aren't dead set on this but we are considering it as an option at this point.

I always liked the idea of vacuum exhaust cutouts! I dont think id ever go for electric cutouts due to the infamous reliability of the electric motors. Plus you dont need to mount any ugly switches anywhere. I say go for the IS exhaust! With the cutouts you shouldn't really have any back pressure concerns either...

Vacuum cutouts also have a switch. I have all switches for mods in the console so nothing is visible.

Certainly an individual choice but I wouldn't write off all electric cutouts. Not all cutout motors are created equal. I chose QTP oval cutouts so the opening can be larger than round options. Motors are not a problem and are more than powerful enough to always seal when closed. Some cutouts are either completely closed or completely open. QTP cutouts are on of those that open only as much as you choose.

What kind of switch would a vacuum actuated, cutout have? Its solely controlled by boost pressure from your vacuum line. Are you talking about the systems where you mount an electric box with a vacuum pump inside of it?

The switch would activate a vacuum solenoid in the same manner a switch would activate an electric cutout motor.

Crystalworks is correct. Without a switch there would be no control over the opening and closing. The cutouts would be opening and closing based on vacuum present, entirely on their own.

Yep. Pretty sure thats what OP was referring to. When in boost, the cutout opens. When not in boost the cutout is closed. A popular mod, that involves no switches.
