Owner of a 991.1 GT3 (Club Sport) and a track has recently opened up in Kuwait. As I track often, been thinking about installing an Akra Slip on (maybe with the pipes in place of primary mufflers) or something similar but have been reassured by the dealership this would/could void warranty. I am looking for a bit more performance and better/louder exhaust notes. In a dilemma and would love to hear your thoughts on this. Should I do it and potentially void warranty? Is it worth it? Perhaps those with experience with this can chime in.
No track noise restrictions... but i do drive the car on the roads, so cannot and do not want to go with straight pipes... Has to be somewhat civil and I am looking to maintain the valve control.
You warranty is with Porsche not the dealer. The dealer doesn’t decided if a warranty is void.
However if you change the exhaust manifolds with cats and or the ECU Porsche will void powertrain warranty. You can change mufflers and you will be ok. However a Porsche zone rep told me a few years ago that if you go completely with no muffler and something happens to the engine like burning a piston the could track it back to less exhaust pressure than what the engine was designed for and the ECU changing the air fuel ratio.
I did just Soul Side Muffler delete. Sounds great, much lighter weight, less heat by rear tires. I don’t want to chance it with messing with exhaust headers, no cats or sport cats and definitely not doing a tune and voiding the warranty.

Thanks for the feedback. Yes, what you are saying makes perfect sense and this was my thought process as well. Question is did Porsche give you anything in writing about the side muffler delete (approval)? Or did you just do it and taking your chances?

Warranty vs Exhaust...
