I've got an 06' LBZ and am looking at exhaust mods for mpg/reduced heat/added power; in that order of importance. Also do not want any extra exhaust noise if possible. From what I've been reading an EGR blocker may be needed to address the possible code setting issues. That doesn't sound good! This also leads me on a quest to get full understanding of the EGR system and all the effects-disadvantages-advantages of disarming the system. Any help from someone who has a complete understanding would be greatly appreciated.
Thanks
