anyone using 2" would 2 " reduce more sound and won't loose too much torque.

how big is the stock piping size on the dx hatch? I am getting a custom bend and thinking of of 2" only instead of 2 1/4 because of the noise and torque.

any suggestion or any one with 2" pipping on their cars..

 

for more torque for your HONDA, use .75" piping. You'll get mad torque y0!

 

It's not going to give you any tq down low like people often believe. Go with the large piping. It keeps the same #s down low, while adding more up top.
