I was planning on turning my non PSE 991.1 C2S coupe into a PSE to get some more sound and some more smiles on my face.

Opportunity to pick up an AWE Switchpath has come up.

Question becomes.......... How much louder is the AWE going to be over the PSE?

From research, it seems opinions vary. Some say the AWE is obnoxiously loud, some say it is nowhere near obnoxious.

AWE says the Switchpath exhaust is maybe 10% louder than the PSE with the valves closed, and around 30% louder with the valves open.

The concern is two fold. The PSE being too quiet vs the AWE being too loud.

Im an old school muscle car guy, who certainly does t mind some noise, and I’m leaning towards the AWE, but figured I’d ask for some fresh opinions and or thoughts.

All other exhaust parts will remain stock as the car is under a CPO and I won’t chance losing the warranty.

 

I JUST did this upgrade on 991.1 C2S, I would say with valves open the car is more like 50-70% louder (perceived volume perhaps not DB) at higher RPM's but in a good way, and with closed valves 10% louder is about right as long as you don't rev over around 4-5K. I LOVE the improvement over the PSE. I felt that the PSE was too conservative for me. If you are an old school muscle car guy, I think you'll really like the throatiness of the AWE on the 991.1. I can't speak of the 991.2 though. Also it does emphasize the over - run burbles in 1st gear. Some people love it, some hate it.

Do you have PSE now?
