Gibson Exhaust Systems Part #615606 Customer Reviews

Disappointing. Not meant for improved sound and performance

I was hoping that this system would give me a deeper/louder tone over stock. The tone is barely louder than stock, if it even is any louder. I've seen reviews say that this system is too loud for them. If this is too loud for you than you need to check your work because you have a leak. As far as performance gains go, you will not notice much at all. It does pull a little bit better in first gear under a load (more than half throttle) but that's being generous.
