About HighFlo Performance

HighFlo Performance began with a focus on high production standards for both quality and sound. With superior designs and engineering there is no doubt we can recreate that old school sound you love. You can count on us to use the best materials and create the highest quality exhaust products on the market today.

HighFlo founder Ryan Westdorp brings more than 20 years of autobody repair and mechanical experience in the garage working on what he loves most, fast cars that look and sound good. Looking for a change of pace after his first 15 years in the business, he found himself in Mike Cederstrom's shop, "Sweet Thunder", learning the in's and outs of high performance exhaust and it didn't take him long to find a real passion for the product.

Sweet Thunder Exhaust Systems has been a trusted brand with superior products dating all the way back to 1979. Their "original" muscle car sound has been proudly and precisely reproduced time after time, in side pipes and chambered exhaust systems.

We are excited to announce that HighFlo Performance is carrying on the Sweet Thunder name and mission, as it was originally established decades ago. We are committed to maintaining the same high standards for quality and sound that Sweet Thunder is famous for. The "Sweet Thunder Side Pipes" brand is managed as a division of HighFlo Performance to bring you the best exhaust systems and components on the market! HighFlo will push forward by introducing new product lines for C5, C6 and C7 Corvettes as well as Ford and Mopar.
