I am going to get some universal quads soon and i help on how to do the piping.

I want to have more air flow thru the exhausts system.
I do not want to lose any power or back pressure.

How about removing cats,not a good idea huh?

Anybody got any piping patterns they can suggest?

Right now i am running with no mufflers since i took my Tsudos off and i like the rumble that it gives out,but it just is not right on the LS.

 

how about same factory pattern with cats. NO resonator and a larger diameter pipe, like a 2 1/2 or 2 3/4. plus a exhaust with removeable silince for insurance.

This might sound stupid but where are the resonators?
