its just like a back fire, shiit just run header and no exhaust, see if it dont really fart, but i like that sound so i dont know why it pisses you off unless its really loud, i mean every exhaust does that, it does it in my accent 1.5 liter, i rev it up just a lil bit and it will crackle a lil bit, but its not loud, if thats wut your hearing.
