Exhaust mods

Has anyone ever made just an exhaust turn down dump off of the cat on their street? Something like the photo just attached at the cat? I realize this will be very loud but I think it would look pretty good as well

You would have next to zero back pressure loosing a lot of low end torque as was as having a good time tuning out decel pops.

You can check out these guys:

They carry a baffle-less double curved pipes similar to what you are thinking. There is also a video so you can listen to the sound.

I think the decel pops can actually damage your engine in the long run.
