I just bought a GMMG exhaust off of a 99 Camaro to put on my 85 IROC. I know I need the 4th gen exhaust brackets, but I can't seem to find the correct ones. I just keep finding universal ones that look like junk. Any suggestions or pics of where I can find good mounts that will bolt right in my IROC? Thanks in advance!

 

I bought mine new and didn't have much luck with the 4th gen hangers either. After clamping it all together and hanging it in place, I drove to my local exhaust shop and had them weld it together and use their "Swinging J" hangers, so named because of their shape.

 

Thanks Al! I have been reading and think I saw that the passenger side hanger works and I just need to buy a 4th gen driver side rear mount and hanger. Does anyone know where I can get one and if that is really all I need? A part # would be great. I just want to have everything ready so I can get this put right on once all of this NY salt is gone. Thanks again!

 

You need the SLP setup. Part # SLE 30044

Here is what my GMMG looks like with it. It bolts right into the stock bolt holes. Perfect.


Passenger side hooks into the stock setup.

 

Thank you Reid! That is exactly what I thought. I will try to find that bracket at the parts store. What did you do about your Cat? Did you put a flange on the GMMG I-pipe and hook that to the Cat or attach it differently? I just know the 4th gen Cats are before the Y-pipe- unlike the 3rd gen Cat. I really appreciate your input. I just can't wait for this snow and salt to be gone so I can get this in and see how it sounds!

Thank you everyone! Hopefully this goes smoothly. MadHammer is hooking me up with the mount. Can anyone tell me exactly what bolts I need to install the driverside mount pictured above by Reid?
