Toyota custom exhaust headers are specially engineered to boost exhaust scavenging and enhance the engine’s ability to breathe. Along with the power increase comes an increase in torque, which will allow you to enjoy greater towing power from your Toyota Hi-Lux. Morgan from Malaga with a Toyota Hilux MK5 2.5 D-4D 102 said: My vehicle is 102 HP 2004 Toyota Hilux 2.5 D-4D with 50,000 miles running 31 10/50 15 tyres. Your chip has smoothened out the power very well! It now pulls evenly through the rev range with no excess fuel knock or injector rattle on overrun, no blacking on power from the exhaust.
