2020 S4 Downpipe options need car louder.

**OrganicBacon** · 02-08-2025 02:34 PM

Hey I have a 2020 S4 Prestige with stage one I have the vps front res delete but its not loud enough for my liking. I've seen a lot of people recommend getting a downpipe to open up the car and make it sound louder and most people have been saying catless downpipe.

I also thought about a AWE Track exaust I would like to know if a AWE Track or a Catless downpipe will make the car louder.

I have no clue which one to get. I heard the Carbnlabs one is good but they went out of business so I saw the CTS test pipe but its pretty cheap and would like to be able to have it for a long time does anyone have any recommendations for catted or Catless downpipes.

I don't mind my car being super loud thats kinda what im aiming for. I also would like to go stage 2 in the future so I would need a downpipe for that.

Ive also thought about the awe track so if anyone has one and has some sound clips I would love to hear it.

Thanks for the help

I have an AWE switchpath exhaust, that made the car much louder with the valves open. More recently added a 034 catted downpipe, now its very loud with the valves open and sounds fantastic. You don't need to go catless to get the sound you're after.

Do you have any sounds clips I would love to not have to go Catless. Also in your opinion is the switch path worth it?

I don't have any sound clips of it unfortunately. If you go on youtube and search around for exhaust soundclips its most similar to a non-resonated touring but a touch louder with the valves open. Is it worth it? Just depends on what you're looking for. I like being able to quiet the car down but I hate that they used the factory valve design and locations. Valves shut restricts flow just like factory since one side is shut off entirely. It also doesn't sound great. This exhaust could have been so much better if they had moved the valve on the drivers side to the muffler exit and used the partial baffled design for valves closed like the passenger side. Really bad choice on cost cutting here. My other gripe is valves closed doesn't do much for the drone around 2500rpm inside the car, its bad with the downpipe but so long as you leave it in D and drive the car normally its fine.
