I am sure that this has been discussed several times on here. I am debating wether to go with a straight pipe or get an exhaust system. The truck has a predator programmer, air raid intake & that is it. I just turned 100,000 so let the games begin. I am planning an egr delete kit & possibly a few other mods. I use this truck everyday to pull equipment & plow snow in the winter. Any info is greatly appreciated.
