Exhaust question

Mazdabater · 02-28-2011, 04:40 AM

So when I got my FC it came with a full 3" exhaust on it, when I fitted the new turbo I made all my dump and wastegate piping out of stainless, and it goes as far as the stainless cat. From there back though it's mild steel and I'm looking at remaking the rest of it. Now tt's not overly loud or anything as it is but what I want to do is put in a Y peice and buy a second muffler because I've always prefered the look of the 2 pipes coming out the back. Basically is it going to be any louder or quieter? I'm assuming quieter as it's the same amount of exhaust gas getting split into 2 mufflers instead of going through one. Am I missing anything here?
