So, I guess folks get to figure out where and how to hide the catalytic converters etc on their hot rod...

Fit the side pipes with catalytic converters. See this link: Catalytic Converters

The Cobra builders in the U.K. and Australia have been facing this for a while now, and AK even makes a special converter than installs ahead of the side pipes: Exhaust Side Pipes 5" with Catalytic Converters - AK Sportscars - Cobra Replica Kit Car

Magnaflow makes 4" OD converters in 2.5", 3" and 3.5" inlet versions (smaller as well), that s/b able to be fitted to side pipes: MagnaFlow Universal Spun Catalytic Converters 54959 - Free Shipping on Orders Over $99 at Summit Racing

Flowmaster makes them as well, as do a number of other manufacturers.

Vibrant makes a 3.5" inlet, 4.5" OD 'Ultra High Output' converter - high flow for high HP engines.

Bottom line is that, while converter placement in side pipes is probably not the ideal location, there are 'off the shelf' solutions available. I'm sure Superformance or other 'Small Volume Manufacturers' could also get custom converters built if that was necessary to sell additional cars.

Given the sound deadening / muffling which occurs in catalytic converters, would side pipe mufflers even be necessary or would the converters be enough?
