718 GT4 GTS Spyder Street Headers

Sounds like a proper GT car!

GT4 - If you’re on the fence, buy these. you’ll love how it transforms the car’s character. Great sound, especially over 4500rpm. No drone. Noticeable torque increase, pulls stronger on corner exit on track. And if it’s important to you, valves closed under 4,000 rpm , sound can be near oem dbs. Watch the obsessed garage YT review for more details.

Awesome product for you 718 4.0L!

This system is awesome and the quality of it is top. Using V Bands really helps/simplify installation. Power-wise you can feel the extra power delivery across the whole rev range. Can't wait for the release of the upcoming rear muffler to complete the system.

Loving my Dundon Street Headers

Dundon Street exhaust frees the GT4 to breath. Car remains quiet with valves closed but sounds and feels incredible when requested. Car has less than 900 miles. The attached video shows first launch experience and testing performance. Dundon exhaust sounded great
