NLS and the car got louder?

[veer90]

I'm not talking a little louder, like 3x louder just normal cruising. Almost like I blew a hole in my exhaust (have full turbo back resonated straight pipe). Happened last night after I no lift shifted 3-4 and it shot a huge fireball out the back.

Weird thing is I drove it this morning and it seems to get louder as it warms up, almost like there's a leak that shows itself with heat. At first I thought a wastegate stuck open but it boosts fine.

Where to start checking? No codes either.

Could have blew/burnt the packing out of the resonator?

Forgot to mention the extra noise seems to be coming from the back of motor / transmission area. I'm familiar with blowing packing out the exhaust but this sounds more like an exhaust leak.

My friend said I should check vbands. Do they pop with excessive pressure?

i cant see that the vbands would be leaking, it might have blown the gaskets out of the downpipe-midpipe connection

Fixed a bad vband and the car's back to normal. The nut backed off because the t-bolt was too long lol
