I am in the middle of picking out stuff for a custom exhaust. I plan on using 2.25" piping, mandrel bends, a 36" resonator, and I have not decided on a muffler yet. I can do all the fabrication my self, that isn't a problem. My question is, how loud do you guys think it will be. I have the racing Mazda header, I don't plan on using any cats because there are no emissions tests here. I want it to be as quiet as possible. What muffler would you suggest, performance isn't as important as volume/price. Thanks!
