I wanna make an exhaust setup with without a cat and with 3 resonators and a muffler. Now, what i wanna know is, with this setup would i lose a lot of backpressure? im thinking exhaust should sound a lil lower than most aftermarkets: 1 resonator replaces the cat, 1-the usual, the other one to make it a lil more quiet, then a muffler. in my head, it sounds pretty sweet. but at the same time, resonators have that "dampening" portion in the design, which im thinkin would give major loss of backpressure if i were to use 3. i was thinkin of going with 2.25 piping...exhaust flow: Header-2.25-3.5-2.25-3.5-2.25-3.5-2.25-muffler. But then again, even tho theres that "dampening" part in resonators, the design internally is whatever material that is used with perforated walls, now im thinking maybe with the perforation, it might give me "some" backpressure.

What do u think i should do? keep the cat, 2 resonators, muffler
or: 3 resonators and muffler
I dont know if im accurate with my backpressure hypothesis. I just want more power with the right amount of backpressure, and kinda wanna lose the cat, and a lil quieter than usual.

Help

 

if i was u i would get magnaflow. I have a apexi and it is the best and the quietest ever
