Custom Extractors
Runner Dia. 1 7/8"
Runner Length 31"
Tuned Length 4-1
Collectors 4"
All our custom headers & extractors
are made so the firing order is in sequence,
Custom Headers
are fully tig welded
The left side
is very tight the spark plugs and remote oil filter
adapter gives us very little room
The front
cross member has been lowered by around an inch, this
helps getting the pipes through the steering to the
collector
The "X"
System
The exhaust gases from left and right extractor mix
in the x section, this evens out the exhaust gas back
pressure, giving the engine a much smoother note. A
slight reduction in overall diameter in the x area,
the exhaust gas speed increases through the x which
helps [slightly] by creating a scavenging effect
The
rear pipes have no choice but to go under the rear axle
[9" diff] the mufflers we used are made by lukey
part L9213
