Pro Fabrication manufacturers and sells everything you’d need to assemble headers or an exhaust system — from raw tubing and flanges to mandrel bends and merge collectors — but they’ll also build you the whole thing, lock, stock, and barrel. And the best part…they don’t even physically need your racecar to accomplish it.

On display at PRI on a big-inch, Pat Musi-built nitrous engine were a set of zoomies and traditional merge headers run by PDRA Pro Nitrous racers Tommy Franklin and Jay Cox, respectively, to illustrate the quality and finish of Pro Fabrication’s all-out race headers.

The zoomies, which traditionally were used on blown alcohol engines, have gained increasing popularity on nitrous engines, and the set shown here will be run on Tommy Franklin’s car in 2018. These use Pro Fab’s CNC flanges and a spring-loaded strut rod for support. The 2-3/4-inch tubes use .035-inch wall at the bottom, and .065-inch wall up top (.045 can be used, depending on the customers’ needs and whether they’ll be using EGT and O2 sensors, all of which Pro Fab can build for). The zoomies use a mixture of 321 and 304 stainless.

“We sell all of the parts and pieces, but we also sell this entire header as a kit, as well,” explains Pro Fab’s Drew Amitrano. “If you’re at home and you don’t want to bring us the car or you have some odd-ball project you’re doing, our kit comes with every single piece you see here. Whatever you want to buy, whether it’s an upgrade, a whole kit, one bend, one bracket, whatever it might be, we’ll sell it to you.”

Whether a nitrous or blower car, Pro Fab tailors the kit to the car. Nitrous cars, when parallel, are often 79 degree bends, while blower cars will typically use 78, 81, 84, and 87 degree bends on the bottom (but those angles can be fully customized). The completed zoomie comes in in the 19.5 to 20 pound range. Pro Fab, knowing the dimensions of the different makes and models of Pro Modified cars from the common chassis builders, built these headers sight-unseen and should bolt right onto Franklin’s car without any issue.

Cox’s headers measure an identical 2-3/4-inch and are four-into-one with a lightweight 5-inch bullhorn. Prob Fab uses an adjustable v-band clamp so you can angle the bullhorn for more or less downforce and thrust from the exhaust. These headers step down in wall thickness, from .049 at the flange to .035 and then back to .049 for structural support and .035 at the collector.

Pro Fab has an order sheet with detailed instructions on measurements that will allow them to re-create the front end of the car in their fixtures and build a high-end set of headers for most  cars without having the car present, saving a lot of time and trouble for the customer. “The best thing is to bring the car, but we’ve done it many, many times and we have enough experience now that we feel very confident that as long as the customer is giving us all of the information, that we can produce a header that fits the first time,” says Pro Fab’s Steve Sousley.
