I have a 2013 SR 4x4 diesel hilux with D4D motor and do quite a bit of towing and highway driving. I'm after a bit more torque so looking to make a few modifications. I should also note that I'm not after a race truck and I don't want a loud exhaust system. Good fuel economy and reliability is more important to me than having big horsepower. Just a mild gain would be great and don't want spend big dollars.
I'm thinking slight exhaust mods and chip?
Any suggestions on brands and configurations?
