SPDZ1 B Series Super Race Spec 4-2-1 Header
SPDZ1 B-Series Super Race Spec header features a true step up exhaust header design. The most innovative B series header design on the market, period. This design delivers extra power throughout the entire rev range. A true power adder with race inspired design, it is the go to header for all serious about making more power!
*SPDZ1 recommends using our test pipes for easier installation of the B series headers.
Recommended for 1.6L-2.0L engine displacements
The significant advantage of these Super Race Spec headers over the classical 2 piece design is that the primaries are stacked next to each other - thus hugely improving ground clearance!!!
Features:
- Made of 304 Stainless steel
- One year limited warranty
- True 2.5" collector
- Computer Machined Designed CNC manifold flanges
- Flange is .38" which is just about 3/8" thick
Note: As per usual, EF & DA owners will require aftermarket subframe/traction bar setups.
- 18G on the 304 S/S. Measured at .049" to .050"
- One piece design
Note: Due to different block/deck heights - on some applications, the sump may need a little massaging for optimum fitment. EF/DA owners will need to modify front subframe.
