Chubbs Posted March 1, 2015 Posted March 1, 2015 Right got a question for you all, 4-2-1 or 4-1? What's the difference? And what's better? Quote
5e colin Posted March 1, 2015 Posted March 1, 2015 4/1 is pure for top end with low torque loss ( best for raised revs ) 4/2/1 is best on stock 4efe it has bit of both lower torque and a bit more top end ( best for stock limiter ) Quote
