hi all .... i have a monaro and i'd like more pure engine sound so i wanted to know ...is the gto exhaust system same as the monaro but without the last chamber which is before the tips/ and without the x pipe ? ( if you look at the gto picures under the car you will notice that at the last there is no chamber before the tips but the monaro does have it) so if i removed this last chamber and also remove the x pipe from my car will it sound like a gto or it's a completely different systems? thanx a lot
