I saw the GB for the Invidia for only $600 and was thinking about getting myself some exhaust. First of all, exhaust is something two people and install themselves with jack stands right?
Second, what is the best bang for the buck exhaust for performance
And, what is the best bang for the buck for sound?
Trying not to spend too much money, which is why the Invidia looks good to me...

Invidia sounds amazing on the track. It might be a bit loud for everyday driving, but it's a good exhaust for a decent price.

As for best bang for buck on performance, you'll be hard pressed to gain more than 3hp out of any exhaust unless you go single with a 70mm piping.

Install is easy and can be done with jackstands and some basic tools.
