Mazda MX5 1.6/1.8 Mk1 2.5″ Decat 470mm to 440/370mm Adapter Exhaust Pipe
This pipe allows you to remove the cat and replace it with a straight through pipe and at the same time allows you to use the earlier type exhausts on the cars that were fitted with the 470mm cat pipe.
This is not a direct replacement part and should only be used if you want to fit an exhaust that was designed to fit with either the 370mm or 440mm cat to a car that was originally fitted with the 470mm cat.
Some of the later Mk1’s had a ladder brace fitted to the rear subframe that was not present on the earlier cars.
If you want to fit the earlier type exhaust you will usually need to remove this brace and remove the mount points on the subframe to get clearance. This varies from car to car and the manufacturer of the exhaust.
This pipe also deletes the restrictive filter and gives the car more power, it is not legal to run this pipe on the road in the UK.
It is painted in a black VHT paint to prevent corrosion. Made from 2.5″ mild steel.
This pipe has been designed to fit with OEM manifold and downpipe.
The pipe is made from 10mm mild steel flanges with a 1.5mm mild steel tube and TIG welded joints, it comes complete with a pair of gaskets and a set of M8 nuts, bolts and washers and a pair of stickers.
