Howdy ya'll

I have a 88 k5 blazer and I am thinkin about changin a few things but lookin for some advice first.

Exhaust: I got true duals with cats (had to pass inspection) on my blazer and it's kinda loud. However, I would like it to be louder. I have no mufflers on ATM, but I was wondering what kind I should get to make it louder. The Louder the better! does anyone have any sound clips I can hear of specific mufflers?

Interior: Thinking of redoing my seats (2 bucket and a bench) in leather. I want either a Grey/Blue two tone leather or a solid blue leather. I have been to Katzkins and they looked pretty nice. Does anyone here know of any other good places to get custom interior work? (I love in DFW if that helps)

Anyway, thanks a lot for the help and I look forward to hearing what ya'll gotta say
