is a muffler good for your engine?
DUDE!! I saw this hemi the other day, and he took a permanent marker and wrote "SUPER" about the hemi emblem, and he dropped two seconds in the 1/4!!!
Oh and back to the OP, my magnaflow on my car is a straight through design, so how does that even help backpressure? I would think it would create a marginal amount, probably not even enough to register.
