Some say to delete the middle resonator and that should increase the volume a bit more. Is this a good route to take? How much will this affect volume and/or horsepower?
I would leave the Magnaflow the way it is. Just in case you add the big boy headers down the road for that extra 10-12whp.

Also for it to stay mellow even with headers. The Magnaflow sounds great as is..
