Which exhaust model for my 2CV?
Just as the capacity of the 2CV has evolved over time, so have their exhausts over the long history of this iconic French car. For this reason, we propose 3 distinct offers corresponding to 3 generations of exhaust. First of all, a primary silencer and a secondary silencer with an inner diameter of 26 mm for vehicles manufactured between 1950 and July 1963. It corresponds to the 2CV type AZ, AZL and AZAM. Then, for models produced between July 1963 and July 1972 (type AZL and AZAM), a primary and a secondary silencer with an inner diameter of 30 mm. From 1970 and the launch of the 2CV 4 and 2CV 6, the most common exhaust systems appeared with two variations, one for the 435 cm3 engines and one for the 602 cm3 engines. All these elements are available on our website. You can select the exact part numbers for your car on our technical site, by visiting our
buying guide (in French).
What are the parts that make up the exhaust systems for 2CV 4 and 6?
They are made up of 4 main parts: the crossbox silencer with a specific reference for the 435 cc engine (ref. 3009105) and another for the 602 cc engine (ref. 1009100). Both parts have an inlet tube centre distance of 490 mm. The swan neck (dog leg) pipe, which is fixed to the crossbox silencer at one end and the rear silencer at the other. At the other end the rear silencer is connected to the rear exhaust pipe. The exhaust pipe has two different lengths. A long pipe for the 2CV saloon cars and a short pipe for the AZU, AKB or AKS vans. The same short pipe is used for the Mehari. These different parts are available individually or as an exhaust kit, which groups together all the spare parts making up the exhaust system. Two finishes are available for all references, classic finish or stainless steel finish to give a chrome, shiny and high quality look to your favourite Citroën.
How to fit a 2CV exhaust system?
To do this, you need to purchase all the additional elements necessary for the installation of the different pipes and silencers. To guide you in their choice and positioning, we offer two technical diagrams on our technical site, one dedicated to the
front part of the exhaust and the other to the
rear part. Please note that our shop also includes thermal protection tape to be wound around the 25 or 50 mm pipes as well as spray glue and the 350 mm stainless steel clamps to fix and hold them in place. These tapes, which are resistant up to temperatures of 650°C, reduce heat radiation and gas density by up to 50% and are used to protect certain peripheral elements against excessive heat from the exhaust, particularly in competition driving.
