Take control of your 7.3 Powerstroke’s performance with the Swag Performance Bellowed Up Pipe Kit — engineered as a precision replacement for the factory up-pipes to eliminate the chronic gasket leaks that rob power and throttle response.
Why This Upgrade Matters
Factory up pipes on 1999.5–2003 7.3 Powerstroke engines rely on brittle “donut” gaskets that are prone to hardening, cracking, and losing seal integrity over time. When these seals fail, exhaust gases escape before reaching the turbocharger — resulting in:
-
noticeable ticking and exhaust noise
-
loss of turbo efficiency
-
reduced boost pressure and power
-
increased black smoke under load
Swag Performance Solution
Our up pipe kit replaces the weak OEM design with a bellowed flange system that naturally flexes with heat cycles and engine vibration. The flexible bellows absorb expansion and contraction, maintaining a solid, permanent seal without relying on fragile gaskets. This means you get:
-
Consistent boost delivery
-
Improved engine breathing
-
Reduced exhaust leaks and noise
-
Longer life compared to stock components
Built for Durability and Reliability
Every Swag Performance Bellowed Up Pipe Kit is engineered for rugged diesel use. High-quality construction ensures resistance to heat and vibration, giving you dependable performance mile after mile.
Complete Installation Kit
This kit includes both driver and passenger side up pipes along with all necessary mounting hardware — making installation straightforward whether you’re doing a DIY turbo refresh or a full rebuild.
