Install intructions for the GMPP street exhaust
 

Anyone have a copy of the installation instructions or have tips/advice? It appears it's nothing more than pulling off the old mufflers and clapming on the new..but one never knows.

i do know you have to measure from pipe that connects to the old muffler back and then cut the pipe. 2 and something inches.

:facepalm: measuring and cutting. I need the printed instructions then.

Very simple swap out, took me lees then 1 hr working on my back in garage. All you need is something to cut the pipe and wrench to tighten clamp.

Apparently there is a debate as to the proper length to cut. 59mm (2.32") as recommended maybe too much because it recesses the tips too far and they will melt the diffuser?:iono:

Go online to the Borla site. You can print them out right there. Borla makes these axle back mufflers.

Thanks, I did that and why I knew about the 59mm measurement. Good tip for others.:thumbsup:

Still wondering what to watch out for when dealing with the tips.:iono:

The mufflers and tips come as a assembly. All you have to do is centalize the tip in hole in rear diffuser before you tighten the clamp. It is very easiy to do.

Gotcha.

I have the GFX on my SS and my GM PP exhaust upgrade came up about 3" to 4" short of the edge of the opening. I am assuming you have the GFX also. There was no tip on the assembly of mine and I have the same concerns as you of possibly melting the diffuser. Dealership says there is no tip for that upgrade. I personally think it needs tips.

I don't have the GFX. And mine already have tips.
