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.
Seriously move the needle on the performance of your 996 GT3 with our Resonance Intake manifold.
When paired with our Street Headers, see gains up to 50whp and 42wtrq!! No tune required, but more is on the table if you do!
By understanding and controlling the pressure waves moving through the intake manifold, we are able to improve the volumetric efficiency of the 996 GT3 3.6L engine to increase horsepower and torque.
You can run this manifold with stock headers, or for maximum gains, pair with our tuned-length headers to unleash your Mezger’s potential!
