just purchased a 2013 1ss a couple weeks ago, is there a reliable vender in the san antonio area or west of san antonio? looking for exhaust (cat back for now) and eventually cam and headers. thinking the magnaflow comp series so i dont have to buy new exhaist when i do add the cam and headers. things will be spread out so i can save the money to get the items, plus im having to work on my 67 ss also. any advice is welcome im not much of a mechanic but if i can do the work id rather do that
