    You can spot the difference easily by the balance tube .The top one is internal (to save space ) the other is the older external mounted one,

    Thanks for the extra info. We have had a response from Waldron Exhaust this morning, stating that their system info shows the exhaust running down the left side of the car, while ours is running down the right-hand (passenger) side.

    "We would like to take a moment and clarify a point that has come to light.
    It is our understanding (from the photos sent and from your conversations
    with Jon) that the exhaust system is running down the right side of this
    1953 Hornet. Our records show the stock system to run down the left side of
    the vehicle and that is what our systems are patterned to fit. "

    What does everyone else have?

    Current position is that we are going to modify both front pipes by cutting slots in the tube and bending where necessary, then locking the bend changes by screwing strips of steel across the gaps and then sending both pipes back to Waldron.

    My concern is that somehow we have a 'bitza' car that is not correct for its year or build. It happens, but would be a real PITA if that were the case.

    I did a quick print out of the exhaust system picture and pages 74 to 78 of the parts catalogue (catalog) but as I said before, info is pretty skimpy in there and it doesn't really define what we should have.

    Does anyone have a picture of the underside of the car?

    Thanks again, very much appreciate the responses.

    All Hudsons from the early 30's onward have exhaust going down the right side. Waldron is messed up. ( My bad experience is from 30 years ago! :)

    Yes ,exhaust on right side of engine if 6 or 8 cylinder. Not sure of the V-8 Hash maybe that's what they got it mixed up with ?

    Thanks again for the responses.

    Had a trip out to SFO on Friday and a day out to the Antique Farm Equipment show at Tulare CA yesterday, but back on the job this morning :)

    I have cut two opposing V's in the first of the downpipes and bent the pipe to where it needed to be. Not exact for obvious reasons, but I can now get the rest of the system installed with no real hangups that are obvious.

    The pipe is pretty strong stuff, and probably won't need anything to stop the cut joints moving during posting back to Waldrons.

    I've now got to swap manifolds and get the 55/56 one on, and see how the other downpipe and manifold look compared to the dimensions we took of the modified first one.

    I've taken some pictures, I'll get the other one swapped and modified and then will post the pictures.

    The Waldron product is nicely made and fits together well, the rest of the systems assembles correctly so far.

    Just as an aside, I found that taking the inner wing rear panel out gave a lot of room to get at the downpipe flange, especially when you have bolts instead of studs!

    Here are the two manifolds and downpipes on the garage floor, the original one has had the downpipe cut and bent, the 55/56 one is just about to go back on the car.

    Getting pretty good at whipping these on and off the engine!

    Due to the strength of the stainless tube, I had to cut much further into the tube than would have been the case for mild steel, but the first one was pretty easy, the second was a bit of a pain as it had bends in the 'wrong' place for what I needed to do.

    Peter, Seems to me that the pipe in your top pic "should" have been a 'plug and play' deal on the 53. Unless I'm missing something,shame on Waldrons...

    Yes, I agree, it really should have been a bolt-up job, but we are in touch with them and they are going to re-work the pipes to the new profiles.

    Back in the UK after a decent flight home, sad to leave Cupertino but work to do and we have an engine show in Holland next month, so it had to be.

    The Hudson is completely missing its exhaust hangers, front middle and back, and while we have the parts book to show what 'was' there, we could do with more information, particularly for the rear mounting that supports the main silencer box.

    If anyone has spare parts that they could sketch for us, that would be greatly appreciated, or if there is a repro source for parts, give us their details.

    I updated Tim before we left so he has all the pictures and details of what I did on the Hudson and the Studebaker Commander.

    Thanks to all,

    Update on the downpipes, Tim has had them welded up at a place in San Jose, picking them up on Monday, $200 for the job. I'll get some pictures out of Tim of the pipes.

    He's going to try them out asap to check on alignment, then we need the brackets/hangers to fit the system.

    Any help on getting these parts would be very much appreciated.
