2022 And Beyond
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.
The Original Sound established in 1979
Sweet Thunder Exhaust
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.
