First-Gen Camaro Exhaust - Headers and H-Pipe

The shorty headers from Hedman worked perfectly for this application. The collector ends right at the area where the firewall meets the floor. This allows the headpipe to be mounted as close to the underneath of the floor as possible, for maximum ground clearance.

Our headers came silver coated for maximum corrosion resistance.
Here's the headpipe coming off of the collector. Note how tucked up the combination is. A standard three-bolt flange adapts one to the other. This was the starting point for our expert exhaust fabricator, Craig Watts of The Muffler Man shop. The first step was to get the correct angle and tighten it in place.

From there, Craig lined up the first length of tubing under the floor. His goal was to keep it as far up as possible without allowing it to make contact.

With a stand holding the rear of the driver's side pipe, Craig MIG welded it to the short piece of tubing coming from the collector.

With both headpipes welded and bolted in place, the next step was to fit the intermediate pipes. Flowmaster sends this section welded together with a balance, or H-pipe, already installed. This helps equal out the exhaust pulses and makes for a cool sound.

A small level is used to make sure the intermediate pipe is installed flat, not twisted. It's attention to detail like this that separates an adequate exhaust system that will do the job from a well-built one that a cool custom car deserves to have.

The dual-inlet/dual-outlet single muffler fits nicely in the stock location. Note the heat shield on the backside that will help dissipate the muffler's temperature where it faces the gas tank. The inlet pipes go up and over the rearend.

The inlet pipes go between the intermediate H-pipe and the muffler. Here Craig trial fits the pieces together. Note that every connection will be welded and that no muffler clamps will be used. The Flowmaster kit does, however, come with clamps so you can remove the system if necessary.
