Exhaust help!!

I have an lq9 swap in my 95 Chevy. Exhaust manifolds into flowmaster collector single 3" all the way back no cats no smog.. I started with a flowmaster 10... Way to loud at throttle.. Moved to a 40. Still has a crackling shitty sound. Heard magnaflow was what I needed.. Bought a 7" round .. It is crazy. Worse than the flowmaster. What do I need ? I love the sound of the shorty mufflers at idle. But driving kills me .

I'm running 2 Borla pro xs's on my lq9 with long tubes, 2.5" pipe, and no cats and I couldn't be happier. The setup is quiet down low with minimal drone and screams once you open it up

I have two of these on two different trucks. I love them. Both are 3" and one is the XL.
