At the moment My wall is sealed up at the rear windows, I was thinking to seal it off at the b pillar which would in turn take a good 5+cubes out of my cab.
Im pretty sure it would make me a bit louder due to less air space but im wondering would it change the peak of my cab?
I want my set up to get low. i dont want to make these trim pieces and just end up peaking higher.
Should i do it or no?
