well right now im running 2.25inch mandrel bent piping from the cat all the way to a greddy evo 2 axleback. with no resonator. its pretty loud so ive decided to buy a resonator to get it welded on.

my question is, will one 14 inch magnaflow resonator be enough? because ive purchased one alredy.
or will i have to purchase an additional 14 inch magnaflow restonator to quiet it down even more?

any help is appreciated, thanks.
