A spokesperson from The Chevrolet Rally Spark Junior F1000 Rally Team has this to say about the performance of Vortex Exhausts on their racing cars:

“As the week of the Goodwood Festival of Speed approaches the Chevrolet Rally Spark has just finished a week of its first test at 3 Sisters in Wigan and the Spark's first rally on the Midsummer stages in Caerwent.

It proved to be reliable and Cameron Davies / Chris Williams drove to a good finish in amongst the front runners. XS Racing now have a good base to build on - and a development programme is now underway to get the car into the top spot.

Thank you for all your support in making the Chevrolet Rally Spark program such a great success”
