2004 - 2006 GTO Exhaust Conversion - Easy Breather

Next, Tom Long, lead technician at Stainless Works, attached the mufflers to the new crossover pipe and secured the right side to the stock hanger. He also used a little bit of high-temp sealant around the slip-fit areas to help seal the system.

Tom then mocked up the passenger side of the system and got it ready for production.

He simply slid the pipes into each other and secured them using the supplied clamps; a little high-temp sealant in these areas wouldn't hurt as well.

Next, he bolted the tailpipe to the stock '05/'06 mounting hole using the supplied mounts and bolt.

After fabricating a near mirror image of the passenger-side pipe for the driver side, Tom installed it as he did the passenger side.

Following confirmation of the alignment on the passenger side, he attached the included stainless band clamps at each flange and snugged them with an impact gun.

In order to mount the exhaust on the driver side, he had to cut the wire hanger off and drill a 1/2-inch mounting hole (as shown) as far down as possible. This hole will be used to attach the new driver-side exhaust.

Next, Tom started to button up the driver side after attaching the tubing to its new mount.

With all the pieces in place, all that's left to do is tighten the rear mounts and clamps.
