I bought Mac longtubes and a Mac ProChamber and SLP high flow cats. I haven't installed them yet. Still waiting to get the headers coated...
I'll post a video of before and after. I think I may ask the guy who is installing to dyno it before and after so I can get baseline levels and then full bolt on exhaust numbers.
