Default 911 T exhaust

Just bought a 2019 carrera T in manual. I want to change the exhaust right away as I like my cars to scream. I love the sound of the IPE F1 exhaust for the 991.2 and want sometihng that sounds as close to that as possible. Curious for opinions on the loudest exhaust available that will make my car scream.
Thanks!

soul cat bypass/delete with akrapovic/kline muffler probably if pure volume is what you're going for.

that said, it's been beaten to death that a muffler doesn't really add any performance benefit beyond weight savings. the stock PSE is basically a straight through system with valves open. i would start with soul cat bypass and expand from there. most cost efficient, and largest volume increase without overspending on no meaningful benefit.

Vektor headers with soul cats are a good combo for better and louder exhaust plus more power and reduced lag. If you want really really loud, add sharkwerks exhaust as the third MOD. Or if you want really screaming, this Vektor header, high flow cat, no muffler exhaust.

I recommend SW if you want to replace the stock muffler. They sound awesome.

1. Soul Cat delete to start. It’ll be loud.
2. add headers if you want more.
3. Stock PSE is basically straight thru when open, but if cat bypass and headers still arent enough a sharkwerks center can bypass is the third step.






soul slash cut matte black tips look great IMO

Does the COBB tune void the warrantee if done by the dealer?

In most cases, yes-but if your dealer is willing to sell and install it for you-check with them to make sure.

yes, if it comes down to porsche looking into a major warranty claim. but if the dealer is willing to do the tune they are usually a “mod friendly” shop and will continue to service the car under warranty... but if something catastrophic happens - porsche can potentially point to the tune and void warranty coverage.

Anyone heard SW exhaust (no other mods) vs Soul Cats (no other mods) ?

Which one sounds better? If you were to just do one?

I can only speak for myself but when my car is backed into the garage on the lift and I start it up to take it out, the fumes are pretty noticeable. My wife often makes comments about the house smelling if I were to open the door into the home shortly after. Driving around, I honestly cant tell a difference-its moving it in and out of the garage for me that the smell is noticeable. For comparisons sake when I had my Supra with a big turbo and no cats-you can smell it at all times, driving around, start up, etc.

Forgive my ignorance, but isn’t an effectively cat-less car (991) illegal?

In many US states, it seems not!
