2007 Clio exhaust system

[Scaffman]

Hi all, new to the forum and just taken delivery of a 2007 Clio that I plan to use on track.
I have a day booked and paid for but think I'm going to have a problem with noise, the seller told me it had been de-catted and was about 98db. I doubt it very much and could do with a bit of advice as to how to sort this out quickly.
I'm sure the question has been asked a million times and I apologise in advance for being lazy and not searching the tech section but I need to get a quick heads up.
thanks, John

Well clio 197 cats are not uncommon on ebay as a lot of people decat them. So just buy one and put it back in.

It must have a system to be that loud though, dont think standard decatted system would be 98db.

Take it to a track when there's a track day on before yours and ask for one of the scrutineers to test your car.
