Grand Rock Exhaust Products

Equip your truck with Grand Rock exhaust products that are a cut above the rest. Pure Diesel Power carries a wide array of Grand Rock stacks, kits, components and modifiers for diesel trucks and semis. Grand Rock exhaust kits are manufactured in the USA from corrosion-resistant aluminized steel and double nickel chrome.

Unlike other manufacturers that use chrome peels and cheaper materials, Grand Rock exhaust products are built to last. With smooth-flowing exhaust through larger pipes, modified exhaust systems using Grand Rock stacks reduce backpressure and enable higher volume flow, giving you enhanced speed, power and fuel efficiency. Buy Grand Rock exhaust products online from Pure Diesel Power today.

Choose from a variety of truck stack kits including turbo-back single and dual kits, T-pipe kits and chrome stacks in Aussie, Turnout, Bull Hauler, Straight Cut and Mitre styles. Order online or contact Pure Diesel Power for more information on any product.
