He posted this in the "what did you do" thread.
To be honest, I don't think I have the time to do it, nor the patience to interact with customers. From a price breakdown, the parts aren't that expensive - but the "labor rate" I would have to charge to do them would be $$$.
Priced from Jeg's:
3" 30/180 mandrel bent SS pipe - $75
3" x 10" SS Flex joint (could probably get away with a shorter one) - $78
SS Flanges - $20
SS O2 bungs - $30
So roughly $200 in parts alone, not including the time to build a new jig/fixture, source pre-bent pipe, find reliable sources and the time to hand-build each one.
ZZP sells this similar setup for the Cruze in 2.5" for $499; while this looks like a potential profit of $300/ea if I were to build them, It would probably average out to about $75 / hour of my time. That sounds like a lot - if I were making enough systems to work full time - but I get so busy at my regular job that I would rather have the time off than the extra money.
This is not to say that I wouldn't be happy to help a local person build one for their own car, but I would do that for free.

Up to this point, I've tuned for max boost, which is a trade-off with spark timing. Just wanting to see what the stock compressor is good for. I have a torque request, but I set a max boost level and adjust my wastegate feed-forward tables to keep the pressure high and come down from there.
The tradeoff is that to control knock, I need to reduce spark advance. So, I need to sit down and figure out if (pulling this following comparison out of my butt) 18 psi @ 25 degrees spark advance makes more power than 24 psi @ 5 degrees of advance, figuring in the increased backpressure as well.
One thing for certain: getting rid of the converters and turning off catalyst protection has net me a bit more leeway in my max injector duty cycle I see at max power - but I still need to limit boost over 5000 RPM to keep from going static.

I'm going to Brighton at lunch to grab my I/C today. It'll give you a good idea of overall ride quality. It'll be a big difference for you just because your sidewalls are taller as well.
I think the eibachs ride well, and if you decide to drop your car, you can bring it over. I have all the tools - we could probably get it done in under two hours if we work at the same time.

Glad you finally got it on!!
Spotted this
It looks like its hitting on really close to hitting. Are you hearing any buzzing or rattles in the cabin. If it is hitting, could this trigger false knock?
Quick adjustment of the charge piping should give you the room you need.
Thank again for purchasing MPFab parts!!

There is NO DRILLING to install this. No cutting either. Goes on pretty easy actually.
