Esteemed 2CV'ers.

I have on my car a section I got fitted by Louie Barbour some years ago, to replace the swan neck/crossbox bit.Its good, I like the feel it gives the car, almost seems better up hills and stuff. It looks like this:

The only trouble with it was it sounds like a bag of nails at certain revs. To counter that, I decided to make it MORE noisey but in a nicer way, and put a cherry bomb on the back of the exhaust.
Its fun, but bloody hell is it noisy. The cherry bomb is starting to rust now and i'm almost relieved, but if I replace it with normal bits I'll have the bag of nails noise back again.

So my question is, has anyone any experience with these kinds of exhausts that replace the crossbox/suggestions on how to make it sound nicer?

Pic of exhaust. (Also with giant funny end piece which I found on the road and looks hilarious on the car.)

I use a Mini RC40 exhaust - only £30 from minispares - has a much deeper thrum than a standard exhaust, side exit by the rear passenger door for that authentic race car look, and also fairly quiet.

Thats a great tip, thanks Nels. I'll stick to the rear exit pipe on mine but I hadn't thought of trying anything off a Mini.

On the farty scale, is it very farty? You would not believe how loudly farty mine is :) Its quite a good noise but since the car takes a while to go by, I'm thinking I'm a noise nuisance. Plus, when I'm home in devon in the lanes, it echoes so much....

Not farty at all I would say - you can rear mount these ok and can get it to exit sideways rear of the back wheel but will need a good exhaust shop to make the link down the side of the car.....

Ah so you've got just the one silencer there. I've got the original style in the middle, running down to the cherry bomb at the rear.

You've got just the one, thats cool. My middle one isn't ready for replacement, still looks new. I wonder if I can stick a Mini one like yours on the rear.

I've experienced that a damper near the end of the exhaust, is the most effective place to tackle the bag of nails kind of sound

If you want it really quite with a good performance than use both RC40 silencers (the small round one and the oval oe shown) with a decent diameter pipe all the way.
I have this om my lowered AZ with M4, it took some work to do it nicely, but it works really well!

The Liege 2cv club did use the exhaust tube of the renault r4 in place of the side silencer. The noise is not much louder but it seems to give a bit more power.
