There is a special exhaust system available for the Burton, which fits nicely under the car, produces a sweet dark rumble and provides some gain in power as well. The damper and pipes are made out of stainless steel and therefore maintenance free.
Assuming everything went well, you should by now have the front silencer installed underneath the gearbox. The mounting points of the Burton exhaust system are different from the ones for the 2CV. For the Burton, you use two rubber exhaust bobbins that have M6 thread at both sides. Use locking nuts to fit them to the chassis/body. Due to high temperatures, it is wiser to use normal nuts and locking washers at the bobbin that is closest to the second silencer.
A new fitting has been developed for the second silencer. This fitting no longer extends from the underside of the car, so it cannot bend anymore. Attach the strip under the two bolts of the rear exhaust clamp in such a way that the strip is horizontally situated above the clamp. Attach one end of the bobbin to the strip and the other end to the chassis.
When the body is ready to be put in place, the thread of the bobbin will touch the body floor. Drill a hole where the bobbin touches the body floor. Fasten it with a lock nut inside the car.
· Assemble the complete exhaust system without tightening the clamps. Check to see that the whole system fits nicely to the chassis.
· The fitting of the exhaust system of the first silencer is done with the use of a so-called half moon clamp of 47 millimetres diameter. It would be wise to use a new clamp for each section, otherwise it may be impossible to obtain a gas tight connection. The Burton Car Company sells heavy-duty clamps that perform much better and can even be re-used, unlike the original clamps. These can be found on our webshop, named 'special exhaust clamp'.
· If you are not able or have a hard time to make the connections gas tight, you may apply (sparsely) a special exhaust sealant.
· The last connection of the exhaust system is attached with a small bobbin to the chassis, as is clearly shown in the picture.
· By lining up all the exhaust connections, you should end up with a tension free fit of the whole system to the chassis. Only then you tighten the clamps securely.
After the body has been installed, you should check it one more time to see if the complete exhaust system still hangs free and does not rattle.
It is possible that the trailing pipe of the exhaust touches a bracket on the chassis or the rear hoisting bracket. Feel free to bend the bracket or to cut it off the hoisting bracket.
