I am thinkin about doin full exhaust including headers and everything, and don't care about anything else besides torque...don't care if its quite (would prefer fairly quite), and not all that worried about costs, as long as its within reason. what would be a good set of headers, good set of mufflers, everything, for torque. H pipe, x pipe, what??? i really dont have much idea about this, but i know that it can't be too free flowin or it could hurt torque numbers. Just want some imput on what would help out torque numbers when i do get around to doin exhaust.
