Dave's Porsche Cayman S
Dave's 2009 Cayman S already has a custom-fitted Hanksville Hot Rods chrom-moly, TIG-welded roll cage. After trying some race exhausts from other manufacturers, Dave found that the off-the-shelf exhausts did not fit the car with its lowered racing suspension. So, he asked Hanksville to custom-fabricate a new race exhaust for this very capable car. The car retains the factory cats, which allows Dave to run on the factory Cayman S tune in compliance with the Porsche Club's Production class rules. This exhaust begins from behind the cats, and is made from 2.5" 304 stainless steel. We CADed new flanges to connect to the cat pipes, and had the flanges waterjetted from 3/8" thick 304 stainless. The pipes then bend upward and well over the axle shafts, splitting the gap between the suspension components and the body without hitting or rattling. The exhaust then bends downward into and out of polished stainless steel Vibrant resonators before bending rearward and exiting out the factory cutout in the rear bumper. We provided straight pipes to allow Dave to swap-out the mufflers if he so desires. With the resonators, the exhaust flows great and sounds racy without being too loud, allowing Dave to run at any of the major tracks that have sound restrictions.
Dennis' Porsche 996
Dennis had previously brought his 944 Turbo to us for custom exhaust work, and we were very happy when he also asked us to fabricate a custom stainless steel exhaust for his twin-turbo 996. His existing aftermarket exhaust was straight-through and flowed well, but resonated quite a bit and sounded raspy. Wanting to tone the exhaust note down a bit and to reduce the resonance and raspiness especially after a cold start, Dennis worked with us to design a new exhaust for his car.
This dual exhaust begins after the cats, tapers up to 3" and uses four straight-through race mufflers joined in the middle by a 3" H-pipe crossover. The exhaust then tapers back down to 2.5" and then uses stock-style tips that extend through the cutouts in the rear bumper. The mufflers and tubes are all made from stainless steel and are fully TIG-welded. We used race-style V-band flanges to achieve a tight, leak-free fit between the cats and the cat-back exhaust.
Bob's Ford GT
The new Ford GTs are truly modern supercars. The aluminum DOHC 5.4 mod motor is probably our favorite engine; top it with a twin-screw blower and you have a powerful combination. The factory muffler, however, is just asking to be replaced by a custom Hanksville exhaust! Bob asked us to fabricate and install a set of straight-through pipes with an X-pipe between them, exiting in the stock location. Although the stock muffler is bulky, there was not much room for the X-pipe, but we were able to fit it with the help of some tight-radius bends, custom-bent here at Hanksville on our in-house mandrel bender. The new exhaust flows well makes the GT sound like the supercar that it is!

Pantera Center
Dennis at the Pantera Center brought his customer’s beautiful green car to us for custom exhaust fitment. The aftermarket exhaust that was originally intended for the car did not fit, so Dennis asked us to modify it. We removed the flanges and rotated them so that they would better align with the headers, then changed the bends on one tailpipe to clear the halfshafts and control arms. With its built motor and big cam, this car sounds as great as it looks!
Mike's Cobra
We met Mike at the All-Ford Day at Bandimere Speedway. While he liked the look of his Cobra’s exhaust, his restrictive muffler was impeding his quest for more power. So, he asked us to install new straight-through mufflers. After carefully removing the existing mufflers from his headers, we TIG-welded the new stainless steel, 4" mufflers and then refitted his existing turnouts and heat shields. The new mufflers look great and really opened up the exhaust on this classic sports car.
Skip's Caterham
Skip said that he had always loved the Lotus 7s, and jumped on this new Caterham when he found it at a dealer in New Mexico. Being a Miata racer and enthusiast, he installed the Mazda engine along with a turbo which promises to provide a great power-to-weight ratio.
Skip needed a custom downpipe and exhaust, and knew that the exhaust would be visible on the side of the car. So, he searched for a shop with a mandrel bender so that the exhaust could be fabricated with continuous bends on the main exit pipe, allowing for fewer weld seams and a cleaner appearance. We were his obvious choice!
We first fabricated the turbo downpipe and blowoff tube, along with the flange that connects the downpipe to the exhaust. We then fabricated the exhaust pipe and attached the Metalcat high-flow cat and Aero muffler, and welded an o2 sensor fitting. Then, we mounted the tailpipe, which runs from the side of the car under the axle to the rear. All components are stainless steel, which provides a great appearance and resistance to the high temperatures produced by the turbo.
We look forward to hearing (and riding in!) the car now that Skip is finished with the final assembly!
