The cat hump is kind of big, and is in the exhaust path. Not really something you want to COMPLETELY remove. There's not THAT much room down there.
You'll need to hammer til it splits, weld in reinforcement, and modify OTS rails.
Example:
Continuing what I was saying about customize some brides, here's pics of what they ended up with, as well as compared to off the shelf Planted for the pass side. Seats are Evo 3's. In retrospect, I wish I'd gotten rails without sliders.
You're close to me, welcome to meet up and see what JE in Baltimore did for me. It'll just be a couple hours labor to modify. PM me.
