since i can't really find the exhaust i want. i'm to purchase the SS exhaust headpipes from mikes but do i need the torque optimizers? I ask b/c the optimizers are actually sold out so i'll have to wait but i really need a exhaust. ill eventually buy it down the road when it becomes available again.
has anyone here feel any dramatic loss of low end torque without opt's running the stainless exhaust??
