Sorry Trev, forgot about the 20VT conversion. Turbo will help with the silencing of course. Try to go for longer that 18" then. It will add a little more weight, but get the db down as much as possible. The silencer will get a little louder over time.

Wouldn't say that Jetex are that good value for money. I have lots of contacts for exhaust stuff so let me know the size you can fit in and i will give you a price. You going stainless or aluminised mild system?
Good luck

Hello Trev, I run a single Hayward & Scott 3" system and the db comes in around 100-102 depending on atmospheric conditions at 75% throttle, hope this helps

Likewise, the old GTti ran a Hayward and Scott single repackable silencer. The key is to make sure the wadding is always well packed before a track day. Jetex components are fine too. You will be surprised at what you come out. The other trick is to always have the clutch depressed when you go for a static noise test, makes a bigger difference than you might think.
