Remember the Gen IV GMMG F-Body Cars?  The Intimidator SS, the Berger Bad Boy SS, the Tom Henry SS, the Hot Rod Magazine Camaro, the Year One Edition Blackbird, the Dick Harrell Edition Camaro.  They were fast, cool and collector cars as soon as you drive them off the lot.  But, best of all was the sound.  People say the GMMG cat-back chambered exhaust is the best sounding F-body exhaust out there.  Sadly, GMMG is no longer making these high performance American muscle cars anymore, but you can still get the same stainless cat back system for your Gen IV car through Mad Hammer!

 

All assemblies are built to the same specifications as when we made them for GMMG.  100% 304 stainless for the tubing, hangers, tips and louvers, all mig-welded together with stainless mig wire.  Clamps are stainless steel.  All material 100% purchased in the U.S.A.  

 

I try to ship within 2 business days of ordering, so generally you can get your system in about a week or less after order.

 

And now, $7.50 of each Gen IV system will go to the Wounded Warrior program.  Mad Hammer appreciates all of our veterans and this is just our way of saying thank you for your service and sacrifice.

 

We'll keep up-dating the site and feel free to send in pictures of your rides with your Mad Hammer exhaust and we'll do out best to post them.

 

We also do the occasional roll cage, zoomie headers and various other items.  We'll be working on selling bent elbows and chambered mufflers so you can build your own custom exhaust during those long winters when your ride is in the garage.

 

Thank you, 

 

Gary
