After doing my cat back exhaust (stock cat dp) I've had my friends start my car and gasp when it turns over. My buds are good eg tuners and he was shocked for me to tell him its a v6. " all the v6s I hear are higher pitched" he said. It's mostly because of design (ohc/ block degree/exhaust manifold/ UN equal length header type/single port etcs.)
All Ive done is a Magnaflow glasspack in place of the resonator and 2 magnaflow street DTM's out back in place of the 2 old mufflers. The magnaflows did this?
