At the moment I have the greddy single exit and I was looking for something louder and more aggressive, I was wonder if I the tomei is louder or would It be better to go for something like hfc or header, if so which one would you guys recommend. Also heard changing the y pipe makes it louder or does the greddy already come with one and if I get hfc will it throw out a code cause my o2 senors?
