Recently bought a CH Lancer that has a crackle/ burble in the exhaust - I was told this is common for them, but surely a modification has been done for this to happen? Would like to stop it and just get a different exhaust system with a meatier sound to it without the crackle/ burble. I like the sound of it on accel, but on decel it sounds absurd. Can anyone offer input? I thought it must have been something tuned in - ie altered timing etc.
