red line

my bad 4500 at 75mph
and 3 rd at 2900 at 70
i read on a post after i installed my flow master muffler that it drones . i wish i would of used another brand
so it s like i feel it s raving high but actually it s just the noisy muffler
i m going to install a resonator to shut it up
but i do have a 294 diff i had it apart to install the sure grip , and i bought it at the dealer , was like 400 canadian
that's cheap!
