oh please do,and any info would be great too.i found it kinda odd because I've never heard them in person so i can't say I'd like the sound or not.I'm kinda torn actually,i don't want something to loud but i don't want it to quiet either.i have no way to gauge what would work.like,i know a 40 series flowmaster is to loud,and the three chambers i had before was on the loud side with my old set up and would be even louder with the new set up.like i said i can't gauge what spintech would sound a certain way.sorry for rambling.
