Punto 2003 8V exhaust silencer hole repair and fuel efficient alternative while improving performance?

[FilippoF]

Hi everyone.
My exhaust's silencer has a hole that I've just patched up with holts gun gum, I might tape it with a holts repair bandage. I'm not sure what more I can do so was considering either changing just the silencer or the exhaust all together. Are there any models that would actually improve fuel efficiency or is it always a case that is going to cost more to run? But so which models are the least costy to run while improving performance and not being loud?
Thank you!

Hi and welcome

Performance exhausts will add noise but not performance or efficiency.

Changing the exhaust manifold might in theory but probably not in practice. And if it removes the cat it won't pass an MOT.

I'd say if your repair gets through the MOT then it's fine. When it finally needs replacing there's no point getting anything other than a standard exhaust.

Due to age I would prefer to replace the rear section of exhaust rather than just the silencer, there's not usually much difference in cost.

Cheaper ones will probably be noisier and less durable, but unlikely to affect performance or efficiency.

Stainless will last if you're planning on keeping the car for another 20+ years

Thank you, `

Do you know what models would work as as upgrade, improve performance, less noise as possible and still pass the MOT?

Isn't the silencer attached par of the rear section of the exhaust already? Or what do you mean?

I mean if the hole is in the back box you have a choice of:
- Removing / cutting off the back box if the rest of the pipe is sound, or,
- Replacing the entire rear section with silencer included

I don't think any exhaust is going to give any performance or efficiency improvements.

For recommendations I would ask in the Punto section:
