[QUOTE="Ouachita, post: 1799976, member: 16802"] I bought a ‘99 single wheel one ton and getting ready to put taller tires on it. The truck has a new exhaust system on it, but the previous owner removed the muffler. The shop must have measured once and cut twice, because there is only one inch between the tire and exhaust pipe. I’ll need to increase that clearance. Easiest/cheapest way is to add a length of straight pipe, but it wouldn’t bother me if the truck was quieter. This rig has been “tuned” or “programmed”, whatever it’s called, and I love it. It gets 26mpg empty on the highway. Question- Will installing an OEM type muffler effect the tuning? In other words, if I have a muffler installed, should I expect different performance, or have to re-tune? [/QUOTE]
