INEOS Grenadier with Kooks Exhaust and Tuner with +50 HP

We have the Kooks Catback Exhausts in stock. We have been waiting to test a "piggyback" tuner which has the capability to add horsepower or even more efficiency at different settings. I am doing testing with a couple different tuners so until the whole test matrix is complete I am just showing the difference at max power. The exhaust operates as in other videos at all operating conditions than hard acceleration. I have posted and is loudest at max power. Cabin noise is less than outside obviously. Here is the link to the Kooks Catback exhaust exclusively through Design Build Go. www.design-bui... #ineosgrenadiers #grenadier4x4 #grenadier #offroad
