We clamped all the joints together and made a few final adjustments to get a perfect fit. Later, well get the system fully welded at the muffler shop so theres no chance of rattles or leaks. Crack open a cold one and admire your workthe system looks and fits better than most custom exhausts weve seen from muffler shops. Between Dougs 17/8-inch primary headers and the Flowmaster mufflers, the exhaust note was sufficiently awesome to cause a parking lot full of import guys to stop and stare as we rumbled by, but its quiet enough to cruise invisibly past Johnny Law. We love it.
