2008-2009 Pontiac G8 GT & GXP Axleback Exhaust J-pipes

Fit In Five Steps

How to replace a Pontiac G8 Axleback Exhaust J-pipes?

1.Locate Exhaust Pipe

Unbolt the muffler assembly at the rear flange connection using a 15mm socket. Pull down on the muffler assembly and squirt soapy water into the rear rubber hangers where the metal rods go thru it. You could use penetrating oil but it deteriorates the rubber. Doing this makes it easier to slide the mufflers out of these hangers.

2.Prepare for Removal

By either pulling the mufflers or prying with a large flat screwdriver or pry bar, manipulate both mufflers out of the stock rubber hangers. The stock muffler is now disassembled and its time to put your new axle back exhausts kit on. Slide each axle back piece into the rear rubber hangers. Align the flange connection and install SOLO’s gasket, nuts, and bolts. Be careful handling the gaskets as the edges are sharp.

3.Remove Old Pontiac G8 GT & GXP Axleback Exhaust J-pipes

Finger tighten both sides and manipulate the exhaust tips into position. At this point, it’s nice to have another set of hands and a good eye to hold the tips perfect position. While holding the tip in position, snug the flange connection evenly.

4.Place New Pontiac G8 GT & GXP Axleback Exhaust J-pipes

While holding the tip in position, tighten the flange connection evenly. A small gap may appear between the flanges. This is OK. The gasket has an inner “fire ring” and as it crashes, it forms a perfect seal but doesn’t crush all the way flat. This extra material on the “fire ring” causes the small gap.

5.Test Drive & Check For Exhaust

The J-pipes only come snug from Solo and can be swiveled to fit your car. Swivel the j-pipes into position then tighten all four (4) band clamps to 50 to 60-foot-pounds or until tight. Jack off the vehicle. Take a road test for part replacing vehicle & check exhaust gases leak out.
