Thanks for all the info. I got a quote of just over £5k for the Armytrix valved system from Tux Auto Design in Cleckheaton who are offering free fitting at the moment. Decision time!

Keeping the original exhaust whether you go with a valved system or non-valved seems to be the way to go.

That does sound good. It would seem that the Armytrix system is the ultimate solution. With the valves closed how close to the stock system does it sound?

Thanks for your reply. I think what you are able to do via OBD is a bit beyond me! I haven't heard of anyone being able to make any changes via Techstream but I'm afraid I wouldn't know where to start but thanks for you suggestion.

Thanks for the response. You make a good point about how a modified car might be viewed when it comes time to sell, not everyone wants a loud exhaust. Is the Blitz Nur Spec a valved system? I couldn't see any mention of it on the link you provided.

Thanks for the reply. I gree that the LC sounds much better, just a shame Lexus don't offer the equivalent for the RCF.

Thanks for your advice. I think the valved system might give me what I am looking for but it comes at a price. Not sure that I could commit to that sort of cost without being able to hear one in action.

Thanks for sharing your experience. It does sound like a valved system might be best but they don't come cheap! Also beginning to worry what a non standard exhaust might do to the resale value, it won't be to everyone's taste.

Thanks for the recommendation. Might give them a call as they are not too far away.

I have a 2018 RCF which I bought two years ago and love almost everything about the car except the lack of a V8 rumble at low revs. When I was looking to buy a V8 I really liked the sound of the Mustang but felt that in every other respect the RCF was the better car. Has anyone fitted an aftermarket exhaust to their RCF that gives that V8 sound at low revs without making high speed cruising too noisy? Ideally I would like to hear what different systems actually sound like before committing to one. I have looked at Quicksilver and Invidia online as possibles, Armytrix is another option but would be quite an investment although it looks like that is a valved system. Any advice would be much appreciated and also if fitting a different exhaust impacts upon the Lexus warranty. Thanks Nick
