i saw this exhuast on the dcsports website, just wonder if anyone has any experience on them. are they quiet ? and what's the size of the pipe ? 2.5" or 3".
where can i buy them ? i need exhuast system for my turbo R . and i need one that's really quiet... perfer looks like stock. wanna be a sleeper

 

i think the dc exuast would be quiet. all their other ones are quiet. do some custom 3 inch piping with a es muffler and paint the muffler black
