  2. Lethal Performance 2011-2014 5.0L Mustang 3" Offroad H-pipe (Aluminized Steel)
    $319.99

    Lethal Performance 2011-2014 5.0L Mustang 3" Offroad H-pipe (Aluminized Steel)

    LETHAL PERFORMANCE EXCLUSIVE!

    NOTE: We highly recommend running this pipe with a custom tune. If you run this pipe without one not only will the car throw a check engine light but you won't fully benefit from getting rid of the cats. So not only does the tune turn off the rear o2's to prevent the check engine light from coming on it will also turn off the Cat Over Temp protection feature in the tune. That feature dumps fuel in order to cool the stock cats. Since the cat are no longer used with this pipe that feature if not turned off will only richen up the air fuel mixture and result in sacrificing some performance.

    Lethal Performance is proud to release our exclusive 3" offroad H-pipe for the 2011-2014 5.0L Mustang GT. Just like our offroad X-pipe for the 2011-2014 5.0L Mustang GT, you can expect excellent gains and a more aggressive sounding exhaust. Our offroad H-pipe is made with 3" mandrel bent aluminized steel and is a direct bolt-on requiring no cutting or welding. Installation should take you less than 1 hour using simple hand tools. Just remove the stock catted H-pipe and install our 3" offroad pipe and you can expect gains of up to 14rwhp.

    Features:

    3" Mandrel Bent Tubing

    Aluminized Steel Construction

    Direct Bolt-On (Requires no cutting or welding)

    Increased Sound and Performance

    Up to 14rwhp Gain Over the Stock Catted Mid-Pipe

    Includes All Necessary Hardware for Installation

    Installs in Less than 1 Hour

  5. DivisionX 99-04 Cobra/Mach-1 High Flow Fuel Rails (Black Anodized)
    $274.00

    DivisionX 99-04 Cobra/Mach-1 High Flow Fuel Rails (Black Anodized)

    Fits: 1999-2001 Cobra, 2003-2004 Mach-1, 2003-2004 Cobra with stock Eaton, 2.3l, 2.9l (Crusher ONLY), 3.4l, 4.0L Whipple, 2.2l, 2.4l, 2.6l, 2.8L, KB 2.8L Mammoth
    (KB Mammoth models require slight modification to the bolts heads which hold the baseplate of the blower to the lower intake manifold)

    NOTE:
    -The divisionX Fuel Rails are sold as the rails only with no fittings. Use the dropdown menu to add the -8an fitting kit which also includes a stock line to aftermarket rail adapter.
    -3.4L Whipple owners will need to purchase the divisionX remote FRPS mount kit. This will properly relocate the FRPS from interfering with the massive 3.4L Whipple compressor. (Also listed as a dropdown menu option)


    All new at Lethal Performance is another amazing product from our good friends over at divisionX. For some time now we've seen the need for a better fuel rail solution. Up until now the rails available to the market had not fit all applications as well as there were a few applications that required modification for them to fit.

    PROBLEM SOLVED!

    As we worked with divisionX to make a better designed fuel rail the objective was to make a higher quality rail than anyone else which will fit all applications. An example of this is the 2.3L Whipple for the 03-04 Cobras. The plenum on the 2.3L Whipple was designed to flow as much air as possible. In doing so it's quite large and causes interference with aftermarket rails. To this day you would either have to grind the underside of the plenum and rail or run a supercharger spacer to space the Whipple off of the lower manifold creating more room for the rail to clear the plenum. For most no one wants to start grinding their $3000+ supercharger and it's kept many from upgrading their fuel systems.

    We're proud to say that the divisionX rails do not have to be spaced, ground down or modified to fit any of the aftermarket twin screw blowers. Fitment has been confirmed on: 2.3L and 3.4L Whipple Supercharger in addition to the 2.2, 2.4. 2.6 and 2.8L Kenne Bell blowers.

    There's more to the divisionX Rails then fitment as they also provide some features that no other rail on the market does. Up until now if you wanted to run an electric fuel pressure gauge you would need a fuel block that mounted in between the aftermarket rail and fuel rail pressure sensor. Same goes for tapping into the rail for a nitrous setup. The additional block is no longer needed with the divisionX Rails as they have 2 ports machined into them already. This allows for you to run the fuel pressure sending unit or nitrous connection by simply screwing the sending unit or NPT fitting into the already machined ports.

    Another huge feature of the divisionX rail is the actual design. Due to the way some other rails on the market have been designed leaking fuel at the injector can occur. This is because the rails do not sit 100% on top of the injectors. They are mounted to the manifold in a way which tilts the rail on an angle and keeps them from properly sitting on the injector. The angled design compromises a secure fit.

    The divisionX rails however have a complete uncompromised fit which sits straight on the injector providing a leak proof seal. Not only is this the way the rails should fit on the injectors but when looking at the divisionX rails mounted on the car they are straight and look how they should.

    divisionX Fuel Rail Features:

    These are the most well conceived fuel rails available for this specific application:

    -OEM positioning, orientation, and size of o-ring seats for injectors.
    -Robust bolt on mounts for safe and reliable injector seating. Stainless steel mounting hardware included.
    -Fuel Rail Pressure Sensor positioned to not interfere with large case twinscrew superchargers. (i.e. Whipple 3.4L)
    -FRPS bank includes a 1/8" NPT fitting for remote fuel pressure sending units for in car fuel pressure gauges. Optional block-off available for return style systems.
    -Auxilliary connection bank has provisions for locking down a Kenne Bell restrictor orifice for FRPS replacement without fear of losing restrictor orifice.
    -Unique low profile design clears inlet of twinscrew superchargers. Overall rail height is the same as the OEM rails WHILE providing a 56% larger bore than the stock fuel rails.
    -SAE o-ring boss ports (-8 size) on front and back of both rails.
    -Front of rails is truncated to maximize clearance in the front of the rails. Aft of rails are positioned to maximize flexibility of supply/crossover lines.
    These fuel rails are machined from 6061-T6511 from a solid block of aluminum. There are no welds or caulk to fail.

    NOTE:
    -The divisionX Fuel Rails are sold as the rails only with no fittings. Use the dropdown menu to add the -8an fitting kit which also includes a stock line to aftermarket rail adapter.

    -3.4L Whipple owners will need to purchase the divisionX remote FRPS mount kit. This will properly relocate the FRPS from interfering with the massive 3.4L Whipple compressor. (Also listed as a dropdown menu option)

    $1,372.80
    Mcleod 2010 GT500 RXT Street Twin Disc Clutch Kit (Street) Includes: Mcleod RXT Clutch Mcleod Lightened Steel Flywheel NOTE: The 2010 GT500 uses a different slave cylinder than the previous 07-09 model years. It has a longer throw. Since the majority of the clutch manufacturers including Mcleod have not redesigned their cluthes yet for the difference on the 2010 model you must use a 07-09 Slave Cylinder with this clutch in order for it to engage and release properly.

Able to handle 1000HP, this clutch kit can handle almost any horse-power you can throw at it and still remain street driveable. Metallic lined clutch discs will provide smooth engagement with a soft pedal effort to make this clutch kit ideal for the street performance enthusiast.

  8. Lethal Performance T-56/T-45 Throwout Bearing Retainer Sleeve
    $119.99

    Lethal Performance T-56 Throwout Bearing Retainer Sleeve

    This is a must for all when doing a clutch swap. As most of us know one of the weak points in the 03-04 Cobra T-56 is the Thowout Bearing and it's sleeve. Most of the time the TOB will go bad and start making squeeking and squeeling noises. If the issue is not fixed in a reasonable amount of time the TOB will wear away at the TOB retainer sleeve and actually snap it in half. This can be a costly problem to fix if you're vehicle isn't covered by warranty anymore. So we have the solution. A High Quality 4340 Forged Steel TOB Retainer Sleeve. The Sleeve comes with a genuine Tremec transmission seal and O-Ring for a perfect fit. By installiing this piece you will increase the durability and life of your transmission for sure.

  9. Reische Performance FORD-G5 170° Performance Thermostat
    $60.00

    These Reische 170° thermostats are custom made specifically for the GT500 with the same size diaphragm and bypass control as your OEM unit. Proper bypass control means maximum efficiency from your cooling system. Each of these thermostats is modified by hand using only U.S. made parts and then quality inspected to ensure consistent opening temps.

    Late model GT500 owners will notice a substantial drop in coolant temps over their stock 192° unit with the Ford-G5 thermostat installed. Whether you are using an aftermarket radiator or not, this thermostat will provide the best possible heat dissipation from your setup along with a faster warm up time and better cold weather performance than a 160° unit or a thermostat with holes drilled in the diaphragm. We believe the 170° opening temp is the ideal balance for high performance engines, providing high flow to your radiator by mid-180 temps while still providing good all season performance. With proper fan settings your coolant temps in cool weather will be in the 170s and in hot weather the 180s, giving those running high levels of timing and/or boost added protection against engine-damaging detonation as well as maximum power output.

    For 2007-2014 Shelby GT500 only. All Reische Performance thermostats ship with a new gasket, coolant ratio/additive recommendations, fan settings for popular handheld programmers and are backed by a 5 YEAR WARRANTY.
