Damien if you start removing any of the back boxes you may gain a few BHP, but you will lose all your torque due to the reduced back pressure. Low down pull and acceleration will be noticeably less. IMO the best exhaust mod for the TS is a straight through cat retaining the back boxes to keep the back pressure up. Just my 2c
