I'm looking to install a cold air intake and cat back exhaust on my sxt. I dont have much money to spend, probably around 600 bucks. I found a CAI and Cat back exhaust by C G S for both it only comes out to about 500 bucks. Has anyone here ever dealt with this brand or at least know some one that has. If not does anyone know other brands that I should go with around the same price range. Thanks in advance.
