borla or magnaflow mufflers blown 340 3" or 3½" ?

I have 3" Borla Xr-1's on my scamp, smallest 3 inch muffler Borla makes...i have to say, they are built great, lifetime warranty, make power, and sound awesome! mine are the sportsmans which are the louder ones

Here's a soundclip i took a while back, not the best quality (had carb issues running like a bag of crap)...i have an x-pipe and dumps too...once you get over 4000rpm it goes from deep to an enraged bark...love it! lol
