I just had the TRD exhaust put on my xD. I notice a little more torque. The engine seems like it needs a little less gas starting out in 1st. Does anyone know what gains can be had from a TRD exhaust in terms of hp or trq? By the way it sounds very good. Has a lot of low bassy note to it and stays that way even in the higher RPM's.

Thanks in Advance
