    Hello everyone, this topic has probably been talked about before but I'm currently looking into getting a exhaust made for my AE86. I've recently installed a built 4AGE Big Port! Hi comp pistons, Big Cams! Porter head and ITB's. I already have the headers for it. What size and set up would you'd recommend? Thanks

    Assuming it's a street machine, I would think you should be looking at an exhaust system that is 2 1/4" Dia. [56mm]. The 2 1/4" Dia. is going to be pretty loud, and a 2 1/2" Dia. system is really loud, you would end up a hand full of tickets. Davew7

    I always used to run 2 and a quarter press bent exhausts on a street driven 4age car. Keep it steel its a bit quieter. I had 4-2-1s, then a cat, resonator and 1 small muffler, it wasn't too loud, until one day I broke it behind the resonator and it was super loud.

    being a built hi comp motor 2 1/2 would be the way to go. you don't wanna choke it going to small. As for loud add a muffler before the diff and after..
