V8 exhaust burble

Hi, looking to get some more V8 burble through exhaust upgrade. Have seen the off-the-shelf units but have not been convinced by related video clips. Nearby specialist came up with the idea of removing centre box and replacing with x-box for balancing flow…Has anybody done this? And could you give your feedback and possibly sound clip, Thanks.

The x pipe will make improvements, I would start with removing the back to mufflers, also check the pipe going over the axle some were not mandrel bent so they are flattened as the curve over the axle, if so might as well replace that at the same time. If it still doesn’t sound aggressive enough remove the mufflers in front of the axle. this is what I am doing to my xk8

Hi, replaced centre box with x pipe…not really much change. Over axle
pipes are flattish so next step I think is replace those and remove the 2
boxes in front of axle…that leaves 2 big ones at the rear…how are you
proceeding??

have a shop mandrel bend the pipe over the axle , i am told just by eliminating the mufflers and squished down pipe you can gain 15 horse. My exhaust upgrade is on hold, i am replacing my rt rear hub assembly
