I didn't realize until just today that GMMG isn't anymore - even though their web-site is still up and looks active.


I had a GMMG exhaust on my last f-body, and now wanting the same on my newer model.


I've read Mad Hammer made the dual chambered exhaust system for GMMG, and I was able to find the Mad Hammer website easy enough. Is this the same system as GMMG's?

Yes, it is the same. I had GMMG and LT's on my old car and the sound cannot be beat.
