Great product, whoever says stock is better is just hating! Stock pipe diameter is just as big but stock is a double walled pipe( so a pipe inside of a pipe)!
Def direct bolt on, and can feel power increase throughout the RPM range, but it is coupled with a AEM cold air intake and full 2 1/2" stainless DC Sports cat back exhaust system!

Feature Product
- Dyno tuned and tested against the competition for maximum performance
- CAD-rendered design with threaded flanges for easy installation
- 4-2-1 design emphasizes low and midrange power for street/strip applications
- CNC mandrel bends with robotically-welded fittings deliver perfect fit
- CNC machined flanges and O-ring seals eliminate leaks
Description
DC Sports 4-2-1 one piece header systems deliver incredible low to midrange power gains, while improving ground clearance and reducing weight by eliminating the middle flanges. The 4-2-1 one piece headers are much lighter than stock systems and are on average two pounds lighter than the two piece systems.
