Photo depicts the stock cat-back single exhaust for 1978-79 Pontiac Full Size (except Grand Prix’s) with the stock 350R. This customer opted to have the tailpipe cut to reduce the shipping cost. You can see in the photo where it has been joined together.
- In these model years the single 1 muffler system is broken down 3 different ways, depending on MY, model name, and engine size. All start behind the converter. Some single cat-back consists of the rear exhaust pipe, muffler, front tailpipe, and rear tailpipe, others consists of the rear exhaust pipe, muffler, and tailpipe, while later years consists of center exhaust pipe, rear exhaust pipe, muffler, and tailpipe.
