^^^^ what he said. Dont take anything off.
In my wrx it had the same kind of headliner the titan had. I had a hot rod interior upholstery shop cover it in carbon fiber vinyl. Paid $75 for labor. Looked amazing and money well spent. I personally wouldnt recommend ever doing it unless youve done it before.
When you're doing corners and angles you have to make all these cuts and triangles to pick up slack in the fabric. When they did mine it have over 250 of these cuts and what not.
Peyton, lemme know if you find a place. or do it yourself...maybe we can get a deal on 2!
