The fit was easy on the Gruppe-S, slid right on, bolted up, and was done. Overpipe too. I put a few dozen miles on it to heat cycle it and then retightended the header nuts before reattaching the under panels. You can run for a little while without a tune but you'll: get a CEL, then lose cruise control, won't run as well, won't see any real benefits. Also the collector and slip flanges on the Gruppe-S appear to be the only differences to the tomei: I compared mine with my friends and there isn't any *visible* difference at all, welds or anywhere else. (I also ceramic coated mine after that for added heatsoak prevention, and was still under his cost)

PLM isn't awful overall, but I've never seen their UEL option. Mostly they just copy other brands designs from what I understand. Link
At that price point you'd be better off with a version of the OFH or a Gruppe-S.

They did

More info on the ofh3 thinking of buying the combo with tablet this weekend will it fit stock exhaust?

You mean the overpipe to frontpipe, yes

From all the for sale adds saying "Header was great, just going a different direction" :bellyroll:

I'm waiting until the test results are in for the 2017 will be interesting to know if more gains achievable with uprated internals.
