Dundon Motorsports Header & Exhaust Packages for 718 GT4 RS / Spyder RS
TAG Motorsports is pleased to offer the Dundon Motorsports Header & Exhaust Packages for Porsche 718 GT4 RS and 718 Spyder RS models in racing applications.
The most powerful header system you can buy for your GT4RS! Our tuned length manifolds and 3" catted "wave pipes" connect to the stock muffler for big improvements in sound and performance! 20whp gains with the stock muffler(more than 32 when combined with our V11 Muffler!). Great torque gains alone but paired with our V11 muffler get even more gains!
TECHNICAL DESCRIPTION
Built to maximize performance and give your GT4RS an exhaust note to match it's stirring intake sound, our Street Header package is the one you have been waiting for!
The GT4RS is very sensitive to exhaust length, and we have invested a lot of effort into ensuring our system was designed to sound great AND deliver the performance you expect from us. With gains of 20hp and 33ft-lb of torque at the wheels, we have achieved those goals.
Constructed from 321 Stainless Steel for perfect fitment and extended durability, this exhaust will keep you smiling for years to come.
Optional V11 Rear Muffler Package
The Long Awaited Dundon GT4RS Muffler: Great flat-6 wail, no drone and big power! Have your cake, and eat it, too!
Great Sound, and Great Power without drone!
We have spent the last TWO YEARS building, testing, iterating and improving this design. Now it's finally ready.
Using the latest technology in additive manufacturing, made from 347SS 3D-printed internals, this design keeps the “valve-open” pathways as short as possible, but still merges the waveforms of both banks for the great flat six symphony we're all wanting.
Nice and quiet when you want it to be, the right kind of flat six scream when you ask for it!
Choice of tips: OEM Weissach Tips, Dundon Polished "935-style" tips, Dundon Polished "Megaphone-style" tips in 3D-printed 316 Stainless Steel!
Makes 32whp at 8000rpm and 37lbft at 4500rpm in additional power over the car stock when combined with GT4RS street header and through axle package!
