l wanna put a Glass pack on my Nissan Maxima. l just would like to know how good it will sound.

''John Paul'' l already know what your gonna say.

Honestly.it is going to sound like a chainsaw gone nuts..in other words terrible. Save your money and put it into a tuned exhaust system that will add horsepower, while still sounding aggressive. Put some thought into your car instead of following this useless and trust me on this one annoying trend.

Its going to sound like garbage.

please do not do it. If you want, upgrade your whole muffler system to the nismo exhaust or magnaflow

check the forum here. these guys will know

Just put something on your car. This is like the 10th time you have asked. It is your car. Find out.
