Building Dual Exhaust Systems

[Build Up Boy]

Need some advice / help on scratch building a dual exhaust system for a 1/24 diecast 1974 Corvette convertible (converted from a 1975 Franklin Mint vette that has a catalytic convertor on it). I've tried a 1/24 plastic AMT vette kit but the exhaust doesn't come close to the proper length or bends in the piping and I just don't care for the little half "there" mufflers. Any ideas or thoughts would be greatly appreciated. THANKS.

You could use solder for the pipes, and scratchbuild the mufflers out of styrene.

I've had luck using Sculpey for mufflers. Make a muffler-shaped form a little big, bake it, then file/sand/cut it down to the right dimensions. You can then drill it and insert some wire that will hold it to the tubing or styrene pipes. Not sure how you'd attach to solder, unless you used superglue or epoxy. The ones I made are two chamber Flowmasters for a Revell '06 Mustang GT. Some aftermarket muffler companies (at least Flowmaster does) have drawings on their websites for helping customers decide which muffler will fit a custom application, and you can use the dimensions to build an accurate piece.

As for the pipes... K&S aluminum tubing, or solder would be my first picks.

I agree with solder for the pipes, but I would use parts box mufflers that look close to what you want.
