2 BBl Dual Exhaust

If its not being tested not sure why you'd even think twice, Hands up for how many guys pulled egr's off? Same thing.

Glad we have no testing here, my dad has stories about the late 70's when he'd pull the protective caps they put on idle mixture scres off fatten them up, can the egr, cat and thermactor pumps at the engine made more power and fuel mileage.

Emmissions stuff now a days works well with little impact on performane, in the 70's they just hurt more then they did good because the technology wasn't there.
