Note: it's not letting me correct the spelling for "muffler" in the title....I need more coffee and it was early)

I am the new (and very lucky) owner of a 2009 GT2. I purchased from a wonderful rennlister. I want to keep the stock exhaust, and the high-flow cats that are currently on the car. I did a ton of searching for the exhaust valve mod that is simple on the 997 GT3, but no luck: simply unplugging the little black electric connector to keep the valves open.

The GT2 is a little too muted at low revs. At @4Krpm it howls beautifully. I am unsure if the exhaust even has the same muffler valves as the other 997 variants I've experienced. There is no exhaust button (as on my C4GTS & 987BoxsterSpyder).

Anyone know the details of the stock exhaust, and if a mod is possible?

There are no valves in the stock 997GT2 system I'm afraid.

@TB993tt Thanks. That's a bummer, so no quick fix other than a new exhaust.

As others have already said, no valves on this particular exhaust. If it makes you feel any better, I'm impressed with how aggressive my 08 GT2 sounds bone stock relative to the 2 996TTs I previously owned. Congratulations on your new GT2!

+1 and have 200 cell cats which the OP mentioned makes the car sound really nice IMO in fact probably the sweet spot for a standard/mildly tuned engine

Thanks Gents. I don't really know how the stock 996TT exhaust sounds as everyone I know has aftermarket. I purchased mine with Europipes already installed, which sound great. I'll live with it as-is for now.
