RS5 exhaust difference between sport and non sport

[spa]

Did a search and didn't come up with much regarding if the non-sport one valved? is there a big sound difference between the two.. tia.

skip it and get an AWE system :)

Yes, but i need a valve controlled system as at certain times I need the car needs to be quiet.

From what I remember when I was researching last year is they are both valved but the sport system has a different tone. I forget whether it's actually louder or not, but I have the sports exhaust and it's not loud enough even with valves open. I've never had a custom exhaust or anything on any car and was worried about the sports exhaust being too loud if you want some perspective on where I'm coming from.

I'm waiting for mufflerman to upload a video of his custom valved exhaust but I'll probably go with that if it sounds good because I prefer to keep the valves as well. Capristo is a popular option around here and it's valved. I believe the Milltek is also valved.

I hear Capristo is very quiet when the vlave is not open.

They are both valved and mostly the same, also in loudness due to European noise regulations, but the resonators are different. The standard exhaust sounds more like American muscle car, where as the sport exhaust more like Italian V8. BTW, the valves are always open above 3800 rpm anyway.

or if you drive in S-Mode all the time :D

Great info guys, thanks! I wondered if a car came with non-sport exhaust and I switched to capristo or any other valved exhaust, if I could control having the valves open or closed thru mmi like guys do who made the change from sport exhaust. I thought I read somewhere that if your car didn't come with sport and you add aftermarket valved exhaust you needed to buy a additional controller.

I have the Capristo but didn't bother with the controller - I do think it's a waste of money (IMHO) to get the controller (it's not cheap for a simple remote!) as you can easily change the ADS Individual setting to Dynamic for the gearbox to keep the valve open.

So you had the non-sport exhaust and now you have capristo? Just clarifying that, if so it's great that non-sport exhaust guys can still have control over the aftermarket exhaust valves via settings in the menus.

not true both sports/non sports are valved. Depending on the year of your RS5 however enables you to have full control of the valves. I believe 2013 Models did not have the "engine sound" option in the MMI therefore the valve control is by rpm no matter the driving mode.

Ok this ones a 2013 so there is no update you can add to get full control? I guess if not that's why people resort to buying an add on controller they are crazy expensive though!!

That's not quite correct. Yes, MY2013 doesn't have the "engine sound" option, but the valves are tied to the transmission mode. In S Auto and S Manual, the valves are open, otherwise they are closed below 3800 rpm. Even with MY2014+, despite the "engine sound" option, my understanding is the valves always start out closed after stopping the engine and you have to quickly engage S mode to get them to reopen.

What I mean by "full control" on newer models is that when the "engine sound" in set dynamic the valves are fully open at all RPM and will not close, unlike the 2013 models that close under 3800.

Yes, I know, but I'm not sure if it's clear that on the 2013 the valves are also fully open at all RPM as long as the transmission is in S Auto or S Manual. Personally, that's usually when I want the exhaust to be louder and if I'm in D Auto or D Manual then I want the exhaust to be quieter. The later model years give you the option via "engine sound" to close the valves even if the transmission is in S or open them if the transmission is in D. If that's desired, then MY2014+ is the better choice.

EDIT: I forgot for a moment, that even in the 2013 if you put drive select in Dynamic and then take the transmission out of S the valves stay open at all rpm. So, the "engine sound" option actually doesn't add that much more control. They just made it a little bit more straight forward to control the valves.

ahh ok I see what you mean. Either way the capristo controller is not needed!

@OP the sports exhaust also is pretty quiet, I added AWE non resonated downpipes to unlock the true V8 sound. Love it! I will probably add the capristo soon when the mod bite strikes again

Loudness IMHO is very subjective. The stock exhausts are deliberately quiet at low engine speeds, but on a canyon run where I keep rpms pretty much between 6k and redline, it screams. I made a similar experience on the German Autobahn during my ED trip. Going 150+ mph for an extended period is accompanied by a constant scream from the back. It was great for the three weeks of honeymoon with the car in Germany, but if I've lived in Germany I could see this getting tiring after a while. I think the stock exhaust tuning really underscores the great GT character of the RS5. I'm not one who is big on attracting attention with a noisy exhaust just driving around town. I leave that up to the Mustang drivers.

I picked up the car that didn't have sport exhaust, it is valved just like the sport version, so I am sure once I switch to an aftermarket valved exhaust it should control the valves the same way any other RS5 does with aftermarket valved exhaust. Non-sport just sounds very civilized, think of it as a even more muffled sport exhaust. All the more reason to plan for a good aftermarket exhaust to play the RS5's song.
Thanks all for the input.

I recently had an issue with on of my rear mufflers on my RS5 (4.2L V8). I had the optional "sports exhaust" fitted from factory. I found a set of rear RS5 mufflers so I bough both and had them fitted to my car. To my surprise, the sound was completely different even though they looked identical to the ones I replaced. The sound was more muffled and softer in dynamic mode, and the down-shifts were not as intense and violent. Quite frankly, I hated it. Upon inspection I noticed that the pipe leading to the valved tip in the sports exhaust mufflers was solid and did not have any holes in it. So basically it was not allowing the gases to expand and enter into the muffler. However, on the non sports exhaust mufflers it was clearly visible that the were holes (perforations) in the pipe with the valved tip. This allows the exhaust gas to enter the muffler even with the valves open in dynamic mode. So, because the sports exhaust almost completely bypasses the muffler when the vales are open, it has a more intense sound and brutal down-shifts. I'll get some photos up soon to show you what each type looks like inside along with the part numbers.

I'm not sure if this is the only difference between the two. The exhaust I purchased included the RS5 centre resonator and from memory the one originally fitted on my car was smaller, but I could not compare as I had that deleted from my system some time ago and did not keep the part.
