Hi my original 172 exhaust is dead rattling blowing etc I'm not after much extra noise atall a little is ok I can get a cat back original genuine Renault system for 200 as I'm in the trade but I've seen the ktec mild steel ones and wondered if they have a better sound if anyone has had one fitted i know about the stainless version but all the videos are way to loud I did that in my Saxo and the drone is too much I prefer a nice meaty sounding idle but that's it really the cars ten years old and I dont see having it over 4 years and a mild steel would most likely last and 400 for a stainless is ridiculous Any vids etc would be great
