sorry to bring up an old thread! but quick question..
im just wondering for general knowledge of our car, when you guys removed your mufflers did you lose torque as you lost back pressure? or do the stock cats create enough back pressure that the loss is minuscule?
if this is true, would that mean adding test pipes or high flow cats to a muffler delete setup would actually lose torque as there is virtually zero back pressure throughout the exhaust?
