First, make sure you'll take pictures of every step... I wanna see exactly how its done... If you can of course.
Second, I would replace perforated pipes but I would leave some holes in them so there is some muffled sound and its not a straight muffler delete and I would also leave cat as well... Also someone on here said that removing the wool material from inside the muffler box would help the sound.. I would try to reduce the amount of it in there..
I wonder when you are in the process of doing it you can somehow rig the muffler closed and temporarily put it back on your car so you can check the sound before you weld it all shut and put it back on....that would be the best to get the exact sound anybody's looking for...right
