The WORKS "Dr. Jekyll" valved exhaust is the
first of its kind! By utilizing a vacuum/boost operated valve; the driver is
able to control the volume and tone of the exhaust on the fly. This is the
perfect solution for your daily driver or dual purpose weekend track toy!
When closed; the exhaust gasses pass through a
straight through muffled section keeping the volume minimal (while also free
In the absence of vacuum (for NA vehicles) or 5+
psi of boost (for boosted vehicles) The valve will open allowing for maximum
Neighbors complaining about early morning cold
starts? Do you commute or travel long distances? Still want an awesome exhaust note
while screaming down the backroads? This is your solution!
Similar to the WORKS ABM; this exhaust features
a free-flowing design to maximize performance with 64mm (2.5") aluminized
steel tubing, a T-304 stainless steel muffler and beautiful 102mm (4.0")
double walled exhaust tips (to prevent yellowing or melting the bumper cover).
The tips elegantly follow the contour of the
rear bumper and directly bolt-on to the factory flange; utilizing all 4 factory
hanger locations. OEM-style hangers are used for precise fitment and all
gaskets and instructions are included for a quick and easy install!
5 to 7 HP gains on N/A vehicles, Turbocharged
vehicles will see higher gains.
Weight savings of over 11lbs!
How is the valve operated?
The valve is operated via a vacuum line that is routed alongside the fuel
lines to the engine compartment and is then teed into the vacuum system. This
allows the valve to open and close dependent on the vacuum situation.
What is different between the naturally
aspirated and boosted variants? Which one should I get?
Both exhaust options follow the same great
design: the only difference being the valve itself. Naturally aspirated
vehicles are to be paired with the "N/A" option. This valve will stay closed
under vacuum and open under throttle. Meanwhile, boosted vehicle owners are
best suited with the "BOOSTED"option. Which opens under 5+ psi of boost.
Will I see a loss of low-end torque?
The exhaust will not result in any loss of low end torque. Due to it's
design; HP gains have actually been seen steadily across the entire rev-range,
not in just one specific area!
