Performance and Application
By removing both the catalytic converter and DPF filter, this system enhances exhaust flow significantly. As a result, you will notice improved fuel efficiency and greater engine power. The larger 4' or 5' stainless steel piping ensures better airflow, reducing exhaust gas temperatures. Moreover, the straight-through design helps maximize flow, making it perfect for off-road and competition use.

- Durable stainless steel piping to withstand harsh conditions
- Available in 4' or 5' diameters to match different performance requirements
- OE-style hangers provide an easy, secure installation
- Straight-through design maximizes exhaust flow, helping the engine perform efficiently
- No bungs, making this system ideal for off-road applications and competitions

Good timely shipping Haven’t installed it yet
Easy installation and sound is awesome
The quality is good, but several spots showed rust signs after one season and one joint is notoriously hard to clamp tight.
