Default Stock Muffler On a Turbo-Back Okay ??

Evening,

Just had a Grimmspeed catted down-pipe installed today and I'm not to thrilled with how loud it is... My catback is an STM https://stmtuned.com/collections/sub...t-2015-wrx-sti
made by a local shop over in Rochester...Great guy's that do top notch work !!! Anyway, wondering if running stage 2 with stock mufflers would create any kind of issue?? One wouldn't think, just wanted to get some feedback before I crawl under there and throw my stock axle-back on to see how it sounds... THANKS !!!!

Running the Cobb Stage 2 93 octane map currently..Stock intake until my injector upgrade

Edit: Thinking I could have posted this in the Tuning/Accessport section ?????, not sure 50/50 lol.... Forgive the double post!!

Totally fine. You'll lose like 2-3 horsepower.

ive done it when I had downpie and protune. Cut all the bass out the exhaust and only left high pitch sound. Didnt sound great but I didnt notice that much of a difference in power
