Dinan Modding The Bimodal Exhaust?

[That_One_Kid]

Here's a general question, but has anyone tried to remove the the baffles from the "sport" side of the bimodal exhaust to get a little more on demand loudness?
Anyone know how Kia baffled the sport side?
I love my Stinger, and I'm about to install my CPI kit, but the things just too darn quiet!

K as the one of the only two boring people on earth who cut open the stock 2022 muffler for fun here’s my advice. Go chop off secondary cats and resonators or simply replace any brand of secondary downpipes and tork oval midpipe then it will be loud enough with little to no drone.

EVC side is not even restrictive at all once it’s opened.

Do you have any more pictures of the innards? I'm trying to understand how it works.
I'm planning on doing the secondary deletes in the near future, I got CPI installed today and while I had the car up on the lift, unbolted the mufflers and liked how it sounded.
My end goal is to keep it quiet but have the option to open it up when I want to, not really trying to get any performance benefits other than smiles per gallon, and for the cost of free.99 can't complain either.

Sadly I couldn’t find any more photos on my new phone. The inner two (non evc side) are baffled as normal mufflers and the outer two are bypassing the baffles. So even the valve opens, the whole inner side of the exhaust will act as a resonator chamber to kill drones. Thanks to kia engineers doing their job properly, it kills drones crazily good. Any modification to that chamber side will ended up with more drones.

Just simply unplug the EVC plug when the engine is off, then the valve will stay open.

Performance wise is actually the least you need to worry about. It’s a turbo car with super restrictive exhaust manifold. Unless you go big turbo kit, it will be there choking the exhaust flow no matter what. People always argue about how the exhaust works or not for our car but most of the time both sides can be wrong. You’ll definitely see power gain after intake/exhaust, but it’s actually the gain from turbo overboosting instead of gaining from getting rid of real restrictions like NA cars.
