I have the 32" and not the shorties which I think are 27". Regardless, IMO they are great pipes and I will buy them again. Quality is not the best but so far mine have held up well and have 2 years ,9000 miles on them. Sound is fantastic and mean as Beavis stated. My first dyno run with them, freak, 160s was 65HP. You can't go wrong for the price.
