Finally had some time to get the exhaust done today. I should have done this long ago...

The exhaust guy wanted me there to watch/help. He was worried that the parts I brought wouldn't fit and that we'd have all sorts of issues. Thankfully it all went pretty smoothly.

The kit I bought was from Kanter, made by Classic Exhaust. It included everything from front to back, and Kanter sent the exhaust flange gasket. That is needed because the flange design is different on the new kit compared to original. Most things fit without too much of an issue. We did have to trim a couple of pipes in the back to get the over-the-axle piece to sit correctly. In the end we got everything level and lined up perfectly. He even threw on a chrome tip to dress it up a bit. I might put on a 50's style tip, but I may just leave it as is.

All in all, took about an hour and a half, and cost me $150 for his time. Money well spent. The guy knew what he was doing and got it done right. Checked for exhaust leaks and none there.

It's like the Panama is a different car now. When I started it up I couldn't tell if it was running or not. The engine is so quiet now. The only thing I can hear are some of the valves and the fuel/vacuum pump. And so far it seems like the car smells better too. Every time I drove it before I came out smelling like I'd been running a weedwhacker or lawnmower for an hour. Fingers crossed that this solves that problem.

I believe that the tip was originally cut at an angle (at least it was on my 1951 Henney-Packard based on the factory blueprint) but otherwise it looks great! It's amazing how quiet a car is with good exhaust.

Thanks Don. Here's the tailpipe with the chrome tip. I do like the look.

If you wanted to try authentic you could keep an eye out for the official Packard accessory tip.

I use the same tip that Kevin has I like the way or looks over the factory accessory. However, one of my parts cars still had the original accessory and I believe that there are, or were, reproductions available. Under the one on my parts car was the angled cut on the pipe itself which, without, pushes the exhaust against the tip and quickly discolors it. Not so with the round tip.

Howard, Kanter has repro's of the Packard tip. I had my eye on them, but when the exhaust guy popped the round one on I decided to leave it as is for now. Maybe in the future I'll change it out.

The smell is significantly improved, but we are still getting far more in the cabin than what we should. It's not coming from the exhaust now, but I'm pretty sure it's coming from the road draft tube. I'm definitely getting some vapor out of the tube at idle....no idea if what I'm seeing is a normal amount of if I'm seeing significant blow-by. Back when I checked the compression numbers they were all high....something like 130+ on all cylinders.

How much of this is coming through the firewall? I haven't put new seals on the heater box (where the hoses enter). And my fresh air duct hoses are in pretty bad shape. The flappers are closed and seem to seal okay, but probably not well enough. I don't think I have any pedal gaskets either. Also missing most of the door weather stripping.

Would fixing all this solve the smell issue? Or should I just do a PCV valve conversion? It does get annoying smelling like a lawnmower every time I drive. Definitely improved after the exhaust, but not good enough.

Nice Job on the exhaust! Door and trunk weatherstripping helped alot in my car with keeping out exhaust and blowby smell. I would say do that before delving into a pcv.

Good advice. I was surprised the other day when I opened the trunk after a drive and caught a lung full of exhaust fumes. Half of my trunk weatherstrip is missing. So it seems like the negative pressure from driving down the road is sucking the fumes back into the trunk, then into the passenger compartment. I'll get that rubber ordered and installed.

I still need to seal off the heater box and check for other leaks in the engine bay. Door weatherstripping is going to be a while before I get to it.

If you haven't done them already don't forget the rubber edge seals on the flapper valves for air vent shut off and heater shut off. The way Packard placed the intakes for the air vent tubes behind the grill, the vents are amazingly efficient in sucking in the exhaust from the car in front of you and can blow past a poor seal. Damaged cloth ducting on the vent tubes either leaking or partially slipping off at one end and leaving a gap is also another good source of engine fumes into the car.

When I took apart the heater box and associated vent, it was apparent that someone before me had replaced the seal with sheet rubber (probably from a tire inner tube). It was in good condition, but not sure how well it sealed. I left it as is. I might need to look at it more closely. As well as the cables to the controls on the dash. For sure at least one of them is broken.
