Can you source 1/8" wall mild steel pipe? That is best for keeping the noise inside the pipe until it reaches the first muffler. You will need more than one muffler. I'm thinking two or three will be necessary. Plan on redoing your exhaust because a 4 cylinder muffler can't flow enough for a rotary and will sound bad.

My street ported 12A has 3 mufflers on it, and the car is still fairly loud. There is a Y pipe and a cap after the first muffler though. I think I am going to uncork it for the race this weekend.
