How much more gains do you get with a canister?? Doesn't a restrictive muffler give you more torque ???
The torque comes from the backpressure. I always thought my car felt better with the silencer in my Racing Medallion. I think you would see a few hp gain going to a straight through design.

is it worth all that noise though? i'd rather be able to listen to music in the car on the highway
to buzzing exhausts

It has been proven on the dyno that a silencer with many exhausts will kill power everwhere on the powerband.

noooooooooooo................. please let this myth DIIIIIIIIIE!
backpressure is always bad, backpressure does not create torque.
HP is just a measurement of torque, so by that logic you would want TONS of torque in the high rpm, but you don't.
Its exhaust velocity which is important. An exhaust will a smaller diameter will be able to keep the exhaust gasses flowing at a higher velocity in the lower RPM ranges. When people upgrade to the larger 3" exhausts with out enough modifications to warrent it, it really slows down the exhaust velocity in the low-mid range.
So they think "Must need backpressure for some low-mid range" but that is not the case. Its all exhaust velocity.
A restriction at the very end of the exhaust system does much less to performance than one right at the collector (cat, which most people leave stock).

Hmm, makes sense. Thanks for clarifying.
