Borla exhaust anybody?

spintechs are a chambered design and chambers kill power....better off with the dynomax ultra flows...Id really like to go Borla- stainless steel, they flow better than straight pipes (hot rod did a test on this with the xr-1 mufflers) and they are loud, but i dont want noise tickets everywhere i go...thats why id like to hear what you guys have to say, but looks like not many here use them...how much would an x-pipe quiet things down? i dont want to use a resonator, so my only sound deadening option is an x-pipe (power increase is a bonus)
