CONCLUSION: If you have the extra cash to spend then get our high flow cat pipe, give up very little power, produce cleaner emissions and make a lot less noise! 
We have about 3 more high flow cat pipes available for our first batch. Our next batch will not be ready for another 6-8 weeks. Order link: http://focus.c-f-m.com/index.asp?PageAction=VIEWPROD&ProdID=1125&dc=focusfanatics
