2017-2021 Honda Civic Type-R / Sport Hatchback DD-R Exhaust System by GReddy

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.

High quality product. Most definitely recommend this to anyone looking for a new exhaust!

Head Turner!

I’ve received so many compliments about how nice this exhaust sounds and looks! Been installed for about a year now and still no problems and still loving it to this day!

Greddy exhaust

Arrived super fast and before I expected it. Amazing costumer service. I will definitely be buying from them again

Super Easy, Great Rumble

The install took less than an hour and the sound was exactly what I was looking for. Not too loud but gives you that deep cabin rumble in idle and rev's sounds pretty sweeeeeeet. Packaging was slightly damaged by the parts inside but none of the parts were damaged at all so no harm done :)

Oh so sweet...

Absolutely in love with this purchase. Took nearly 9 months to arrive due to what I assume are material shortages, but it was on the car within hours of arriving. Greddy really nailed this one, I love the grumbly, bass-y notes you get off idle with this system. The cat back has a depth and a tone that cannot be captured by the videos and sound clips I had watched before receiving my own. Everything about the build quality, materials, and fit just screams factory+. Installation was a breeze. Took one star for a defect I can only assume was inflicted when packing the box, seems that someone hit one of the silencers pretty good in packaging it, I'll include pictures of the ding and scratches. Not visible when on the car, but still slightly soured my unboxing experience after a near 9 month wait for my not exactly cheap exhaust. All in all, Greddy and Maperformance nailed it.
