This Jag XK was entrusted to us by it’s owner who was very concerned about getting the sound just right from the exhaust of his pride and joy. Several options were explored but we developed a design that we expected to produce the right sounds and avoid the need for a special box to be made. The system featured a crossover which helps even out the exhaust tone by equalising the pressure in the 2 systems, helps reduce noise slightly and on certain occasions on some engines may give a slight power gain. The exhaust note was gorgeous when we fired the car up, a purposeful growl when the engine was revved settling to a gentle burble at idle yet going almost entirely silent at cruising speeds. It’s great to build a system for an engine that makes such a lovely noise to start with.
