Has anyone thought the RS sounds great at start up, then quietens after about 10 seconds as the exhaust flap closes ? I know removal of the system would raise a fault light, but has anyone tried removing the flap or perhaps drilling it full of holes to reduce its sound damping abilities?
Thoughts or ideas appreciated, don’t fancy changing out the exhaust as it would effect the warrant, but the meaty sound at start up should be there all the time in my opinion
I’ve had a Riverside Racing cat back exhaust fitted for a couple of reasons one that I think that it looks fake when exhaust fumes are only coming out of one tail pipe unless the valve is open. You can see the write up under the exhaust section.
I’ve also seen a video on you tube where they make it sound better when the valve is open by welding a bypass bit of pipe from the main exhaust to the tailpipe with the valve on this bypassing the silencer when the valve is open, this is all done on the standard exhaust. Mines the same on the Riverside Racing exhaust and it makes a great noise when the valve opens and yet civilized whilst cruising around in normal mode. ?
Brilliant, Thanks for that, I really like the idea of that, simple way to obtain added exhaust noise without huge expense, possibly ignored by Ford warranty? After all, you still have the original exhaust
It’s just another Possible Exhaust Flap Mod for JohnyBigarms to think about.
It does save pressing the sports button every time ( the stop-start button is a right pain as well ! shame there isn’t a permanent off switch for that!) and maybe prefer fewer pops and bangs with the Exhaust Flap open.
… Sounds like a mod worth doing now, thinking about it!
My understanding is a cat back exhaust will not invalidate warranty .. only the exhaust part of warranty .. and replacing with a stainless steel as we all would then you have nothing to worry about as most exhausts come with a lifetime warranty ??
