1 • NEW Pie Cut Stainless
Steel Universal Exhaust Bends
This clever innovation is prefect for creating
complex bends in exhaust systems. The kit
consists of six segments, each precision cut
from stainless steel, designed to interlock
and rotate. This enables you to form bends
of various angles. Each segment features a
16-tooth and groove click system, securely
interlocking with adjacent pieces. Allows
precise alignment and ease of assembly
for welding. The segments can be rotated
in 22.5 degree increments. Supplied in
packs of six, which is sufficient to create
a simple 90-degree bend or various other
bends. Each piece is 15 degrees angle.
Single segments also for small angles or
for complex curves. Sizes 35mm to 127mm.

3 • Airtec MIL Light Cheater
If you’ve recently fitted a de-cat or high flow sports cat to your car and you
have an engine management light come on, then you need the Airtec MIL
Light Cheater. This Lambda sensor extension can solve engine
management light issues. This removes lambda sensor from the direct gas
flow. It is recommended that a remap is still installed to ensure correct
engine tuning.

£95.75
An easy to fit, universal baffle system which inserts into the end of
the exhaust system and clamps onto the tailpipe to reduce exhaust
noise. Originally designed to combat stringent noise limits in the
Britcar race series the Decibel Slayer utilises a perforated tube which
penetrates the tail pipe and has an optimised length to leave exhaust
gas flow unrestricted while effectively reducing the noise level.
Designed to fit tailpipes between 2-4” diameter including oval
with no extra clamps or welding required.

This unique exhaust packing is
designed for controlled expansion
under heat from the exhaust. This
ensures the silencer is properly
filled, even those with complex
shapes, providing maximum sound
absorption. Installation is simple as
the material can be cut with scissors
and only has to be loosely wrapped,
the exhaust heat does the rest.
• Easy to install
• Proven on road and track
• Reduces silencer skin temps
• Lightweight compared to
traditional wadding
• Supplied in pre-cut sizes to suit
