We are extremely excited to present our F-Chassis 3" Hi-Floâ„¢ catless downpipes! The only TRUE 3" 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 amazing N63 engine even more responsive!

Downpipes are available with both factory style connections - slip fit, and 2 bolt flanged. Please VERIFY which version is on your car, as Real OEM is not always correct, even with the VIN number!
Fitment for all F Series Chassis with the twin-turbo V8 N63 Engine

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 1500°F. Such temperatures will also rapidly deteriorate the polished finish.
