Just finished these 2x Mercedes Units for Hinks Haulage and what a result we got. 1x Mercedes 2548 EURO 6 and 1x 2545 EURO 5 and both are as loud as each other with a distinct V sounding note even on a straight 6. Check these vehicles out at Truckfest Malvern in a few weeks as you will not believe in the flesh how good these sound! Big, big thanks to Hinks for the business.
