Quiet exhaust options?

1177 Views 41 Replies 21 Participants Last post by  Rabid Atoms
I think I go against the grain here, and prefer quieter exhausts over louder ones. The Race exhaust drives me nuts and I have to wear noise cancelling earbuds when on a drive of any length. What are my options for quieter systems?

1. The factory sport (non-Race) exhaust is said to be quieter.
2. The Novitec is valved with a quieter mode, but I can't find it for sale in the U.S.
3. The Quicksilver appears to be valved as well, but I can't discern if it is quiet and loud, or loud and louder 馃槃

Any other options I've missed?

The factory Akrop is totally acceptable on the highway in Normal mode. I am not sure I can hear the exhaust note over the wind, road and engine noise unless my window is down. If I switch to Dynamic mode I can hear the difference inside the cabin and if I lower the window I can really hear it.. This is in a Spyder with a CF top that has the sound insulation..

The factory muffled exhaust is very quiet, this one is fairly cheap if you want to try it:


I believe you can buy this one for around $2,800 and have it shipped to the US, it's valved with two options for tips:


I have the Quicksilver non valved. Love it. If you鈥檙e in the FB Group 鈥淎lfa Romeo 4C Club鈥 you can watch/listen to some vids here:


It鈥檚 much more tolerable without being boring or losing character. 馃憤馃徏

I tried the Quicksilver non valved version and still found it too loud. I have fitted the standard muffled exhaust and that is fine, apart from speeds around 80mph when it is a bit boomy.
if you decide to put the standard one on you will need to get the mid section too as it is different to the race exhaust centre section.

Mine鈥檚 been on for 7 years without any issue. A simple, cheap and reliable solution to killing drone. The Quicksilver Helmholtz has much to recommend. The stainless steel has kept its shine too. A quality item. The noise is reduced inside the car not outside but the noise outside is more melodic. Character is maintained.

One more reason to go with Akrapovic. I drive in dynamic and then when I come home and back onto my lift I put it back in normal and it doesn't bother anyone in the house.

Would be nice if we'd be able to listen to all of them. Design of the (inside of the) muffler defines the sound. I find the race factory (apart from being way too loud for my liking, opening post could have been mine) also to sound like an old car with broken exhaust. Which in fact is true: short pipe, no muffler.
How different eg from a Yamaha R1 or Kawasaki Z1000 with eg Akraprovic, who sound dark and melodious. My Giulietta QV also sounds dark at low revs and higher pitched at higher revs. Would love such sound in the 4C as well
