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.
Do you want more power for your Porsche? The Dundon 997 Resonance Intake Manifold is the perfect way to add some extra horsepower to your car. Our intake manifold will increase engine performance and give you a smoother, quicker acceleration. It's also designed with a larger throttle body that helps lower resistance while still maintaining the same air flow. Check below for all the details.
On our 3.8L test car we increased the power from 400whp with race headers alone to 440whp with race headers.
We recommend a high quality header (like our race or catted header) that moves peak power to 8300-8500rpm
* Fueling and ignition MUST be tuned with this part.
