Product Description

If you’re looking to add power, performance, and good looks all at once for your next modification project, look no further than AR Design. Expertly handcrafted in the USA, all AR Design products use the best quality materials available. All exhaust components are built from 304 Stainless steel with water-jet cut or CNC’d flanges, and are available with a ceramic coating rated up to 2000 degrees Fahrenheit. Painstakingly welded, AR Design does not grind or polish the welds to preserve the integrity and heat resistance of their parts – besides, with clean, even, and precise beads like this, you’d want to show off your work, too! AR Design stands behind all of their products with a lifetime warranty against manufacturing defects and a three year warranty against rust and corrosion.

Are you the kind of person that wants it all – more sound, more power, and less turbo lag? This AR Design downpipe kit has you covered. These downpipes produce more power than stock while giving your car an exotic tone and a race-bred attitude. Each downpipe kit also includes AR Design’s exclusive “bomb-proof” exhaust gaskets and grade 10.9 metric hardware for increased durability. Best of all, high-flow cats are included, so your car will remain street legal.
