Any exhaust available that don't need a butcher?

Don't think this has been asked before.

Are there any exhaust available that actually bolt to the manifold or cat?
I really want to get a decent sound out of the Clio but don't want to start cutting up the standard exhaust.
If I need to return the car to Renault for warranty work it needs to be easy to return it back to stock and make it look like it's always been like that

Something like a Yozzasport might do the trick. It's a decat system though. There is one (or was) one in the classifieds. I think it's being sold by Goose.

Standard exhaust will always need cutting to remove, unless you drop the rear beam.
