I am new to the site so cut me a brake. I live in Pennsylvania and want to put an exhaust on my 05 crew cab. Qquestion is, can I do a turbo back without the cat in Pa. and also I want a jet engine sound and not a hot rod rumble. Second question is getting 18 inch wheels and tire combo that will withstand the towing on a weekend basis of a four horse trailer loaded up. Any picks or info would be greatly appreciated. Thanks!
