AR Design R56 Hi-flo Catted Downpipe
Description
|
This is a set of very high quality AR Design 3" stainless steel downpipes for the R56. They are 100% hand tig welded in the USA, and completely 304 stainless including the flanges and bungs. They are argon backpurged during welding to ensure full penetration and no sugaring on the inside of the pipe. This particular set is for downpipes with high flow cats.
We are extremely excited to present our R56 3" Hi-Flow™ downpipes, now with Magnaflow race cats! The only TRUE 3" catted downpipes currently on the market! In addition to an intoxicating and exotic sound, these downpipes add significant power and virtually eliminate turbo lag, making the fabled engine even more responsive!
Our Hi-Flo™ 3" Downpipes w/Race Cats Feature:
- The only TRUE 3" catted downpipes currently on the market! 3" tubing until cat-back flange - all systems currently on the market reduce to 2.5" much closer to the turbocharger.
- 100% hand crafted in the USA from premium 304 Stainless Steel (cats are made from 409 Stainless) - flanges and O2 bungs included!
- Water-jet cut 304 Stainless cat-back flanges, and CNC'd 304 Stainless V-Band flanges.
- Magnaflow 3" metal substrate race cats
- 100% TIG welded, argon back-purged.

- Available with a 2000°F ceramic coating. Coatings come with a 3 year warranty against corrosion and rust to original owner.
- Lifetime warranty against any manufacturing defects given to original owner.
- We do NOT grind/polish our welds as some other manufacturers do. Grinding welds compromises the strength of the weld, and can lead to weld failure! Especially critical in applications exposed to temperatures in excess of 1600°F. Such temperatures will also rapidly deteriorate the polished finish.
