It's not fun, but if you've ever read a Hellion install thread they're not far off. It's a little more involved on the '13+ cars with the need to redo the IC brackets. My biggest gripe is the lack of an exhaust hanger. On3 leaves the end user to figure one out on there own, which my guess is most customers won't put one on, and will lead to cracks in the header. The instructions could use more pictures, but there's enough pics in build threads to get it done.As twin turbo installs go, I've heard the install for this is absolutely dreadful? Fitment isn't all that great is what the guy said.
Otherwise the piping was nuts on, hot and cold. Hoses, drains, brake lines, it was all good. There's a lot of people that have had fitment issues, but on the flip side myself, other home installs, and MANY shop installs had zero issue with fitment. I was impressed with the piping.
stretchb, were you having MAF signal issues? Looks liek you're running the Paxton setup? I ran the Pro-M Wave with a super smooth signal in the stock piping, was fearing the worst on that one.
