I still think it sounds like crap. I keep telling everyone the only way your going to get that deep growling sound is to remove the 2nd set of cats on the down pipe of your boxster. Have you ever heard the Boxster with no exhaust? It's very loud. Now just imagine it with only 1 set of cats instead of 2 sets. EPIQ sells the bipass pipes. Then you can add whatever kind of mufler/exhaust you want and its still going to sound good because of the removal of the 2nd set of cats. Suposed to be emitions legal and it's a bolt-on job so you can reverse it if you don't pass your emitions. :dance:
