1946 Exhaust System

Jim Kilday

Other than longevity, is there any other valid reasons to install a stainless steel exhaust system from Waldron's vs. having the local Silent Knight custom build the system? I think the cost savings installng the carbon steel system is a couple hundred bucks but if there is a good reason to go stainless, then I'll do that.



Also, is there a muffler I can use that will produce that special noise we used to get with Smithy's glasspaks? In fact, will a Smithy's work or does it's smaller diameter increase the back pressure?



Thanks,

Jim, I had my exhaust replaced last year on my hornet. It had 20-25k miles and nearly 20 years on it. Anyway the tailpipe was just carbon steel and had the expected surface rust but was still solid as can be. The exhaust pipe was alluminized and was still like new. The entire new system is alluminized and was built and installed by a local shop. Regardless who bends your pipe, buy alluminized its not much more than plain carbon and will last like stainless without the cost.

As for glasspacks, they are a straight shot at your exhaust diameter or larger so they one slight step below a straight pipe as far as restriction. Atypical muffler though larger diameter is far more restrictive. Not sure on the spasher, but with a 308 the glasspacks literally are a headache for those behind you. A steelpack which is similar construction gives a better sound with the same performance.
The shop that did the work I mentioned, didn't stock steelpacks so I opted for a flowmaster and am pleased with the sound. I wasn't sure I'd like it since I had associated the flowmaster with how they sound with the whiny modern cars.

FYI

Being on a budget Aluminized has worked exceptionally well vs expensive Stainless pipes. However, I do recommend a Stainless muffler since its the lowest point where moisture will collect.....
