    Money Well Spent!

    I love this exhaust on my Z!!! Videos don’t do the sound justice. It definitely gets people to look twice when they hear it. The black chrome tips look fantastic as well.

    Great Growl

    I always use Corsa and am never disappointed. Gave my Z06 a nice low idle growl and brought up the volume driving but it is not what I call loud. Tone is great and nice to hear it echo at low speed versus the factory near silence.
