got a set of Wileyco pipes for my SV. Warning, TLS cans don't mount up correctly to the midpipe flange of the SV. The inside diameter of the wileyco cans are .250 smaller than the flange of the SV pipe. so i had to dremel some slots and cout down the flange diameter to fit them on. it was not a pretty job, but its completed in a couple hours. i must say it sound farking AWESOME. its got some balls now! i love it.
