Need exhaust help
When I first got my 2010 SS (L99), back in March of 2014, I deleted the 2 rear cats and the mufflers. It sounded great. But me being only 19, I wanted it louder so I recently deleted the resonator. It sounded awesome at first but since then I've been hearing a very strange noise from the exhaust. Almost like it's running rough or something due to possibly "back pressure"? When I hit 1000 rpm from a stand still, you don't even hear a grumble, just what seems to sound like air and something bouncing around the exhaust. Also when I let off the gas and it downshifts, it sounds like it's just pushing air out the pipes. It sounds great when I get on it though. Any answers or solutions? I'm thinking of just putting the resonator back on although I've heard of several people also doing what I did but they don't have the same noise I am hearing. Please help! Thanks

Back pressure, no! Have you checked for leaks?
For the record, you did nothing more then waste you time and enhance your AFM by deleting the resonator. |

I turned my AFM off when I first got the car. And yes, leaked have been checked for but i have a feeling not good enough.
