I've been searching but cannot find out 3 things:

1). Is there anyway to keep the low end torque without a muffler? I like the burly sound flowing just from the straight pipes but don't like the loss in low end torque

2). What muffler keeps the most low end torque while muffling the least amount of sound?

3). What can we do to increase the low end torque? Larger injectors? Sparks plugs? Headers? Intake? Any ideas?

Thanks!
