718 GT4RS V11 Muffler

Dundon Motorsports stands behind our products with a 30-day love it guarantee. We are confident in the quality and performance of their upgrades, but if for any reason they don't meet your standards or help you push your performance on track, you can send them back within 30 days.

Some products are built locally and made to order. Typical lead time for welded components (mufflers, headers) is about 7 business days after purchase. In rare cases timelines may change—we’ll notify you by phone.
