[QUOTE="CATDiezel, post: 870367, member: 4387"] You guys need to study "jet engine propulsion 101" Bigger is not always more efficient or better, and likewise lower EGT's does not mean things are more efficient either. :doh: Just ribbin alittle. !! But seriously, your backpressure is more important to take note of than a 30-50* drop in EGT's. The factory double walled pipe is nice for my quiet ride in my humble opinion! I will be "magicolly" surprised if it frees up ANY pony's at all with a stock turbo truck. Even a modded truck for that matter.... BE interesting either way. [/QUOTE]
