I think I must of heard most that are available for the isF in person now, which in my opinion is the only way to decide before parting with your cash. So if you just want that extra little bit of V8 burble a few hundred quid will just do it.
Cutting off your rear boxes is fine for the extra A+B road antics but get on the motorways and the drone for most is unacceptable.
Lots of systems available just depends how much you are prepared to pay most are from a little over a grand to five thousand, it's the percentage value to the car that most need to be wary of I guess.
Now I posted up about the Uk company Quicksilver and the Rcf,s they did for Lexus and it was Lexus who approached them, I initially listened to them like we all do on line and i thought I need to hear that in person.
So as luck would have @Flytvr has had their cat back system fitted to his Carbon Rcf and it is without a shadow of a doubt absolutely stupendous from the build quality to the noise and zero drone at motorway speeds. Just after he had done I took the below couple of clips unfortunately usual iPhone rubbish speakers better on headphones.
With the intention of going back to the airfield to get some full chat runs which we did but the weather was appalling and prevented filming but those of us that were gathered there agreed it is a fantastic deep V8 menacing old school system sound with all the pops and bangs that bring the car to life.
