Going From Dual to Single Exit

Z's

I dont comment nor participate as much as I'd like to on this forum, but when I say the choice between single and dual is completely a personal choice, it is. Almost all power differences between dual and single are negligible and it's always argued over. The Z community where I live constantly bickers over it and it's just ridiculous. Up until the HR 350's I believe, the stock exhausts were single into a dual exit muffler anyways. I personally run a single exit Tomei but my girlfriend has a Motordyne and it sounds beautiful, better than my car, but I'd still take the single because it's preference. By the way that ISR is gonna be louder than what you have for sure.
