Re: first mod suggestions?
First mod, smooth tubes and filters.
Second mod, high flow cats and a catback exhaust. It will help with the heat inside the cabin as well as the UPS truck stock exhaust note.
PS. Theres no reason to gut the cats. Just remove them entirely if you're going to go that route. They cant be seen from underneath the car anyway. Still though I would go with high flow cats over complete deletion, although I dont know what TX smog laws are like.
