Default Issues running open Hooker LT headers?

Any issue with the O2 sensor in the collectors? Thinking of ditching the exhaust since looking at limited street use now.

I've heard guys having problems with the cool air causing their o2s to go bad but I've run like that for awhile and didn't have any problems

you wont pick up anything with open headers. atleast run yourself a Y to a 4" collector or do dumped true duels with an X pipe

When I dyno'd headers only, I lost tons of low to mid end torque. But the peak power was very good. After adding 18" pipes to the headers, a very generous amount of that lost torque returned with a vengeance and the power remained roughly the same. At the least, run around 18" of torque tubes.

Right now current setup is true dual 3 inch exhaust through Magnaflow mufflers dumped before axle, just thinking it would save a little on weight, but i guess if it hurts power, scratch that idea

Nah, you'd want to run extensions for sure. Hope you like loud!
