I’m pretty sure that there are tons of muffler threads on this site, but I didn’t look because 9 times out of 10, they would be out dated info anyway.

I have an 2004 A6 S-line and I’m looking to buy some mufflers for it. I don’t want to get the whole exhaust system done because it’s still under warranty, so right now, I’m just looking for a nice sound. Something like the 350Z/G35 stock sound. So my question is, what would be the best muffler I could get for this car?

 

Just for the sound? drill a couple holes in your old ones

 

I think the Vibrant mufflers sound nice but it's your taste. Go to You Tube and search for audi exhaust and you can hear a few different exhausts sounds. Don't even think about drilling holes, that's just dumb and unjustifiable.
FYI - the G35 is not a true dual exhaust. It's one muffler cocked side ways with two pipes coming out each side.

 

lol i think he was being sarcastic but yeah those Japanese are very tricky!

 

Nope it's true, buddy has an 04 G35 Coupe and I took a look at itsince they do sound nice and found out it was one muffler with 2 tips.

 

i love Japanese !! I got one in my electrik generator !!
Hmmm, d u talking about S6 ?

 

I was thinking about a Magflow or a turbo muffler because they kinda sound ok for Japanese car. I've heard that Remus Mufflers sounds good on BMW's, but as far as Audi's go, i'm not too sure.
