Fswerks is great. Good price and good quality. Had mine for about a year. But it's a very subtle upgrade from stock. I have Cp-e now and can't believe I ever had anything else. Sure it's pricey but well worth it. If you don't like noise, stay away. Great tone. I'm crazy and just switched out the resonated section for a straight pipe and it's crazy now. But I love it. Either way, it's an excellent option.
