With our distinctive style and design, the Greddy Performance Products DD-R is our modern take on the highly-sought after GReddy DD “Dynamic Dual” exhaust of the past.

Our iconic DD exhausts have always been recognized for its aggressive dual exit look and deep GReddy sound, but with this new DD-R, we also incorporated updated and improved full 304 stainless-steel construction.

The GPP DD-R has been adapted to modern tuner cars to not only enhance the looks and sound, but to improve performance with its carefully designed dual high-flow straight-through muffler layouts.

Another new feature on the DD-R is the tunability. With the new twin removable tips, new options for tips finishers and silencers, now allow the owner to fine tune the looks, sound and flow of their DD-R.
