CUSTOM EXHAUST PARTS

Jetex are probably the U.K's leading supplier of universal exhaust parts for road, race or rally use.

Parts are available with diameters of 1.75"(45mm) to 5" (127mm) in either stainless or mild steel (some parts are made from aluminised steel). Unique silencer fabrication allows 2" boxes to withstand temperatures of up to 600 degrees centigrade (for normal road conditions), while our 2.5", 3" and 3.5" boxes can withstand temperatures of up to 800 degrees centigrade (for higher powered engines and when used for race and rally applications).

Choose from a wide range of pipework, bends, silencer boxes, adaptors and tailpipes to construct an almost endless variety of free-flowing, power enhancing custom exhausts to suit your own unique application. Together with our range of Sports Catalysts, Jetex offer the total solution for road or race conditions.

With the recent addition of oversize 4" (4 inch) and 5" (5 inch) exhaust parts, almost any exhaust application is possible with Jetex custom parts:

  • Standard Road Use
  • Performance Road Use
  • Track Cars
  • High Performance FiA Race Series
  • Truck Racing
  • Drag Racing
  • Lorry or Truck Exhaust Repairs
  • Large Tractors
  • Heavy Plant Machinery
  • Industrial Use

Straight Lengths and Bends

Straight Lengths: Available in 1.75", 2", 2.5", 3", 3.5", 4" and 5" diameters. Mild or stainless steel. 1m or half metre lengths. Pipework dimensions are outside diameter. One end is flared/slotted.

Mandrel Bends: Available in 1.75", 2", 2.5", 3", 3.5", 4" and 5" diameters. Mild or stainless steel. 30, 45, 60 or 90 degree angles. Pipework dimensions are outside diameter. One end is flared/slotted.

Tight Bends: Available in 1.75", 2", 2.5", 3", 3.5", 4" and 5" diameters. Mild or stainless steel. These bends are constructed using two pressed plates welded together. Pipework dimensions are outside diameter. There are no flared ends with these parts.

180 Degree Bends: Available in 1.75", 2", 2.5" and 3" diameters. Mild or stainless steel. These are mandrel bends. Pipework dimensions are outside diameter. There are no flared ends with these parts.

Over Axle Bends: Available in 1.75", 2", 2.5" and 3" diameters. Mild or stainless steel. These are mandrel bends. Pipework dimensions are outside diameter. One end is flared/slotted.

 


Adaptors

Double-End Sleeves: Available in 1.75", 2", 2.5", 3", 3.5", 4" and 5" diameter. Aluminised or stainless steel. Dimensions are outside diameter. Ends are not flared or slotted.

Stepped Adaptors: Available in 1.75", 2", 2.5", 3", 3.5", 4" and 5" diameter. Aluminised or stainless steel. Dimensions are outside diameter. Ends are not flared or slotted. 4" and 5" stepped adaptors have one step. All other diameter adaptors have 2 steps.

Y-Pieces: Available in 2", 2.25", 2.5", 3" and 3.5" diameter. Aluminised or stainless steel (2", 2.5", 3" and 3.5" only). Dimensions are outside diameter. Ends are not flared or slotted.

T-Pieces: Available in 2.5", 3" and 3.5" diameter. Aluminised or stainless steel. Dimensions are outside diameter. Ends are not flared or slotted.

X-Pieces: Ideal for V6 and V8 engines where each bank of exhaust gas should be brought together before separating again. Available in 2", 2.5" and 3" diameter. Stainless steel only. Dimensions are outside diameter. Ends are not flared or slotted.

 


Silencers

All silencer boxes are straight through absorption designed. Noise is reduced by absorption through a centre perforated tube. The tube is wrapped with stainless wool and then filled with blown basalt wool. Consequently, there is less gas flow restriction and so back pressure is reduced, torque is increased and engine performance is enhanced.

 


Flexible Joints - Polylock

Polylock flexible hosing is ideally used in low impact applications. These parts should be used further towards the back of the exhaust and in low stress conditions.

Polylock hosing dimensions are inside diameter. To fit this hosing to existing pipework, it has to be slotted and clamped, or welded in place.

 


Flexible Joints - ILOK

Our range of flex connectors is ideal for use before the catalytic converter where temperatures are high, engine movement is high and there is considerable gas noise.

Iloks can withstand up to 1100 degrees centigrade. The interlock liner creates an air gap between the liner and bellows improving the cooling of the exhaust gas.

The main flex bellows unit is made from stainless steel to take front to back exhaust movement, while the stainless outer braid helps prevent torsional exhaust movement. Pipework can be inserted into the end caps allowing the flex to be welded in place.

 


Flexible Joints - Compensators

Compensators prevent fracture between the downpipe and the rest of the exhaust system.

Available in 2" and 2.5" (aluminised steel) and 3" diameters (stainless-chromium steel). One end is flared/slotted.

 


Flanges

2 Bolt: Pair of mild steel flanges with gasket.

3 Bolt: Pair of mild steel flanges.

3 Bolt Flange Assembly: Pair of mild steel flanges with 'O' ring, with extra stainless pipework welded to each flange.

 


Universal Backboxes

Our range of universal back boxes can be fitted in conjunction with our 2", 2.5" or 3" parts, or fitted to an existing exhaust system. Please note that these back-boxes have to be adapted to suit an existing exhaust and will not fit straight on. However, by using adaptors from our custom range, this can easily be rectified. Tailpipe styles include Twin Round 57mm, Round 100mm, Round 100mm slash, Round 114mm, Round 114mm slash and Oval 90x120mm.

Oval Back-boxes are available in stainless steel (for 2", 2.5" and 3" pipework).

Round Back-boxes are available in stainless steel (for 2.5" and 3" pipework).

 


Universal Tail-trims

To finish off a custom exhaust or to improve the look of a standard exhaust system, Jetex offer a wide range of tail-trims (round, oval, square, slash-cut and many more) to fit 1.75" to 3.5" pipe diameters. We offer clamp-on or weldable tail-trims.

 


Pipe Spacers

These small, but very useful mild steel parts allow two pipes to be joined together by filling in the space between them.

Jetex offer a wide variety of fittings to allow parts to be hung correctly under the car.

  • Rubbers: Many styles available.
  • M8 Rubber Cushions
  • Hanging Straps

Decibel Reducers

Ideal for sound reduction when using 2", 2.5" and 3" pipework. Decibel reducers should be placed inside a minimum of 300mm length of tubing and self-tapped or welded in place. These parts are a cost effective method of sound damping.
