hi guys, Loving the GTS thus far. Want to get a bit more sound than what the PSE + AWE center muffler delete offers. In my previous 997.2S I had Gundo and SW, and while the car was totally tame below 3K, above 3K it was louder than the GTS.

Looks like side muffler delete is too loud and almost obnoxious... thoughts?

Other options is to add a 200 CEL cats - any feedback on these cats alone? The headers are already upgraded via the X51 package in the GTS, so not looking to change those...

ideas?

thanks

Cats. Tons of threads on this

If you do cats in 997.2 you're doing headers to. They're connected unlike 997.1. Try disconnecting PSE plug. Keeps flaps open all the time instead of closing at certain rev ranges/speeds when on.

Otherwise you're looking at new mufflers.

Don't run open pipe. I did it for kicks while replacing my third muffler with Sharkwerks bx.
It sounds like ****.

You could also get more volume if you replace the stock intake with a CAI. I have a CAI + SW bypass + plenum. It howls above 3500 rpm or so.

Unconscionable

Only option aside from headers is new muffler, but I would prioritize headers above muffler.

Ideal to do all this with a dyno tune, of course.

Sure, you could get some hack job with higher flow cats welded into your stock parts, but that's nonsensical.
