Pacemaker vs Xforce vs Difillipo

[H1GHROLLR]

i had an xforce system on and i could not think of a worse sounding system , cheap,nasty and sounded like some one farting into a road cone sold it the next week (almost feel bad for selling it and not just giving it away) now i have di fillipo and it is awsome, worth every cent, nice low down thump but when you feed it to it it just gets louder and louder +1 for di fillipo

i'd be aking the question between try y and 4/1, primary size, collector size and length, X over pipe, 2/1 or full length duell.
so many differant setups with so many differant opinions.

phoneing exhaust shop who have no affiliation and dont have a supplier agenda my yeald a profesional opinion without bias.

Well guys, I have a x-force system, 1 5/8 4 - 1 headers, high flow cats and 2 1/2" cat back, all in stainless, and I don't mind the sound, nice and crisp note, nice sound, but maybe I just got a good one.
