Hi,
My exhaust man says 'X' joint not required on my car. Says 'X' joints are for cars that have completely separate systems for each bank of a V engine, enables the two banks to be connected.


My stock system is quite simple - down pipes from each primary cat, along to the secondary cats and then out into a 'Y' joint, then single pipe straight into the muffler. No resonator, is the resonator a US requirement ?
