I went to a local shop to discuss exhaust options. They recommended an 18" Magnaflow and increasing the tail pipe to 2.25. They quoted $220. The shop said that this may give a slight increase in horsepower but may also result in a loss of torque. I don't think it is worth giving up off road/climbing performance in the hope of gaining a few ponies and maybe a .5 mpg increase. For those of you that have increased tail pipe size, have you noticed any loss of torque?
Thanks.
