The girls find a way to reclaim the sensory experience of an exhaust for an owner whose daily driver is an electric vehicle; his weekend ride, a Karmann Ghia, gets a little aesthetic boost with a dual-carb setup.

Bogi and Faye go back to their roots and tear down an old air-cooled VW engine that Faye had lying around; using all new parts, they build a short block from the engine stand up for a project that Bogi is working on back at her shop.

The 1961 Volvo PV544, the Iron Maven, was an all-women SEMA build; it's in the shop to fix a no-run issue, and to add an exhaust system to get it sounding as good as it looks.

Many would say there is nothing cooler than a classic wagon, and if they are talking about this super clean '67 Malibu, they aren't wrong; it's in for a disc brake upgrade, an ignition system update, and some fixes to the dashboard.

This Monte Carlo was on its way to being one awesome street machine until disaster struck; mice made a home of it and destroyed the interior; Bogi and Faye replace the interior and try to fire it up for the first time in a few years.

The owner of this truck finally found his dream vehicle, but like a lot of classics, it has more than its fair share of leaks. Faye and Bogi go through the truck and show how to fix some common leaks, while discussing different ways to find ones that are hard to trace.

Bogi and Faye found this 1972 Challenger at a customer's house when checking out another one of his vehicles. When they learned it was potentially a triple black, they began talking about helping him restore to original. It all starts with rebuilding the numbers-matching 340 engine, and finding out a little about the car's history.

A GTO that has spent a lot of its life in shops with mechanics who had no intention of finishing it, is brought in by its owner for some final touches, including checking gauges, air conditioning and the steering column.

Bogi and Faye show how a worn-out Toyota's steering rack and pinion works, where they fail, and how to rebuild it with a simple rebuild kit.

Bogi and Faye describe a common failure problem on a fifth-generation Camaro. The torque converter can fail in the transmission, causing the car to shake at 40-50 mph. The girls upgrade the factory torque converter to fix this problem for good.

Cars die of boredom, so it wasn't great for a Plymouth Prowler to sit in a museum for 15 years; the girls show what areas to fix before the car gets back on the road.

The girls bring in a rare Caprice cop car to bolt on a supercharger from a second-generation CTS-V; they'll make brackets for the intercooler, bolt on the supercharger and give the rare cop car some extra power.

The girls take an old AMC Spirit drag car and get it ready for the street by changing out the oversized carb. They bring in a special guest to help them pick out the right carb and tune it on the car.

Bogi and Faye show how to rebuild and upgrade an R154 manual transmission so it will last as long as the Toyota engine; they also drop a valve body on an automatic transmission, drilling it out and adding stronger sleeves to keep it lasting longer.

The girls have to figure out why an '87 C10 isn't running anymore; they know it's a fuel problem that happened after an EFI setup was installed; they finish up with a new disc-brake kit; Bogi takes a field trip to show how custom fuel lines are made.

Bogi and Faye both learned how to wrench on Volkswagens, so it's only appropriate to bring in Faye's 1980 Rabbit for her to learn a little fabrication; the driver and passenger floor pans are rotted out, so the girls weld in new ones.
