Good to know, makes my decision even easier! Was really interested in going Race+ but wasn't sure about rasp.

I see your MS x-pipe on your site, do you guys also stock donut gaskets and the M10 star bolts/nuts (header to x-pipe)? I was going to grab some from ECS Tuning but would be easier to get all from one vendor.
