Love it
I have the Scotty II and love it. Sounds cool, and lots of cool air. EGTs go up slower and lower and come down quicker and lower ( if that makes sense?) U gotta cut the hole too. Its not too bad. I cut it, used a dremel to smooth the sharp edges and primed the bare metal to protect from Michigan weather. I had a AFE Mega canon and I like the scotty better!
I'm also working on an idea, possibly with a 4'' sliding "blast gate" from my wood shop dust collection system to put on the end that goes to the cowl to show it down in the winter to allow quicker heat up and reduce grid heater cycles. U would slide the gate closed in the winter to reduce COLD air flow. I'll lets everyone know how it works once the kinks are worked out.
My 2 cents.
