Anyone running a bully dog 6' exhaust on their 94-02 CTD? I'm thinking about buying to replace my current 4' TB thats on the truck. My dodge has some mods and is putting out about 45psi but I could probally get more if I changed out head studs. Will the 6' exhaust affect the performance of my truck I don't want to take any any power of course but i'd like to have something different than a 5' or 4'
