Dyno Notes
Once again, max power was made on a spike, but if you compare the power from the header run versus the previous run there was an easy 10 horsepower made.
Pros
This thing makes a shit load of power! Main reason was in the header design and removal of the factory primary catalytic converter.
Cons
This header removes the primary catalytic converter. Only one O2 sensor bung is welded on the header, and the car is equipped with two. Hotshot does provide an extra O2 bung that needs to be welded after the secondary cat-the O2 sensor wires need to be extended as well. Dyno results are based off of Hotshots method. However, we tried to fool the O2 sensors and got the same result.
Parts Included
Header, exhaust gasket, weld on O2 sensor bung and plug for weld on O2 sensor bung.
Tools Required For Installation
10mm and 14mm socket, ratchet, extension, 12mm and14mm wrench, 22mm wrench, welder (or reliable muffler shop) and wire.
Install Time: 2-2.5 hoursIncluding welding time
