Silencers
JP Exhaust silencers are all hand made at our Macclesfield production facility. We make many types of silencers in any sizes to suit any application, from standard OE replacement to repackable race to 4ft diameter silencers for the North Sea oil industry.
     
Tube Bending

JP Exhausts have two modern efficient mandrel bending machines allowing fast turnaround. We can supply bends to various angles in a range of different sizes and radius in 304 stainless steel or mild steel. We also have 4 press benders giving us great versatility

All tube wall thickness is 1.5mm unless stated otherwise

Bends can be between 5 - 180 degrees

(CLR is the centre line radius of the bend)

1.38" (35mm) diameter CLR 2.36" (60mm)

1.5" (38.1mm) diameter CLR 2.28" (58mm)

1.625" (41.28mm) diameter CLR 2.95" (75mm)

1.75" (44.45mm) diameter CLR 2.95" (75mm)

2" (50.8mm) diameter CLR 3.54" (90mm)

2.25" (57.15mm) diameter CLR 4.72" (120mm)

2.5" ( 63.5mm) diameter CLR 3.75" (95.25mm) - 5.11" (130mm)
     
Components

JP Exhausts can supply everything that is used to manufacture the exhausts / manifolds in component form, such as:

 

Laser cut flanges

Lambda bosses and plugs

Tailpipes in a range of styles & sizes

Perforated tube

Stainless / mild steel sheet

90 degree bends from 1.5"(38.1mm) - 3"(76.2mm)

These can be used by the budding enthusiast to build their own exhaust or repair damage to an existing one.

Please contact us with your requirements

Collectors
As you can see from the examples below, we have a wide range of collectors available
Rolled sheet collectors that can be two, three, or four into one with infinite tube size possibilities
Basic 2 into 1 pressings
High flow merge collectors which are made from four individual tubes carefully cut and welded together
     
Catalytic Converters
Here at JP Exhausts we only supply metal substrate cats (no cheap ceramic units). We have two distinct ranges:
A high quality vacuum brazed metallic core substrate ideal for high performance applications. These are available in 100 / 200 cells per square inch (CPSI). 100 CPSI gives the best gas flow, but for cars with the latest OBD2 on board diagnostics a 200 CPSI cat is required. These catalysts need to be matched to horsepower, with a maximum single cat set up of 375bhp on turbo cars, although twin set-ups can go up to 750bhp.
A budget range of metal cored shelled cats which are available in 200 CPSI or 400 CPSI and are aimed more at road going cars with below 200bhp.
There are various shapes and sizes in both ranges to cover most applications
