Pypes Turbo Pro
Love to have you get a pair of our mufflers but if the Dynomax super turbo's gave you drone, the Pypes super turbo's will give you very similar drone. Internally, they are very much the same design. Things to check:
1. Make sure the exhaust system is insulated from the body of the car with rubber hangers.
2. H-Pipe is not helping. An x-pipe smooths out the tone much better.
3. You may end up needing a pair of resonators in addition to the mufflers for your application.
