Question & Answers

1 Answered question

can the muffler be used as a dual inlet and single outlet by turning it around and not losing any flow or tone?

Asked by mark from whitefish mt on

Hi Mark, This muffler from Dynomax is a chambered design and the manufacturer does not recommend reversing it. The exhaust flow would be affected. Thank you for your inquiry.
