DETAILS
We are extremely excited to present our N63/S633" Hi-Flo™ downpipes, now with Magnaflow race cats! In addition to an intoxicating and exotic sound, these downpipes add significant power and virtually eliminate turbo lag, making the amazing twin-turbo V8 engine even more responsive!
Our Hi-Flo™ 3" Race Catted Downpipe Feature:
- Typical gains with tuning in the 200-25bhp range!
- 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 5" bodied metal substrate race cats
- 100% TIG welded, argon back-purged.
- Grade 10.9 Metric Hardware (145,000PSI tensile strength, C32-C39 Rockwell, Zinc Plated), and Nord-Lock positive locking re-usable washers included.
- New rear extended oxygen sensors included
- 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.
