So i've had the Z for 3 weeks now. Purchased all stock. It was entirely to quiet, so i went with the Invidia Gemini exhaust system. It sounded good, very quiet, stock almost, but when you get on it it was a tad louder than stock.
However i wanted more noise. So i cut off the resonators and welded on some pipes.
Massive difference. I love it. It is louder, enough to turn heads but not to wake up the neighbors. There is just a hint of drone but nothing major, especially cruising in 6th gear.
