Hi, is there a aftermarket source for SCS exhaust system to stock manifolds (390) ?

I don't want a loud cackle setup.

thanks.

 

Your best bet would be a local muffler shop. Any decent shop can pretty much bend anything you want whether it's single or dual exhaust.

 

The local muffler shop to me is run by a knucklehead. Hence I would rather buy a kit myself to follow stock routing in a SCS.

 

I've run across businesses like that before, usually they don't last long unless they are (1) actually really good at what they do, or, (2) they're the only game in town.
As for the exhaust, the only listing I've been able to find is for the 155" wheelbase models, yours is 140".

 

You didn't state the year so I arbitrarily chose 73-74 to do a parts search for NOS parts. Usually there aren't a lot of NOS exhaust parts because not that many people go to the dealer for exhaust work.
The parts catalog shows four major parts, I didn't bother searching for the hangars and clamps.
The cross-over pipe (inlet pipe) is sold in two separate pieces.
LH Inlet pipe D3TZ-5246-B
No dealer or obsolete suppliers have one

RH Inlet pipe D3TZ-5246-E
Perry Pitre Ford, Eunice, LA has 1 (337) 457-4111

Muffler C7TZ-5230-M
No dealer or obsolete supplier has one

Exhaust pipe D3TZ-5255-C
Reagor Dykes Auto Co, Plainview, TX has 1 (806) 293-2511

 

I have a 73 super camper special myself. I looked at several exhaust systems. Could not find any that I thought was worth buying. If you have saws and a welder. But some pipe and bends and a couple down pipes and build your own .That way it is the way you want it. I made my exhaust it's not hard just time consuming

 

I meant buy some pipe. Not but some pipe. Damn auto correct

 

No saws needed... two grinders - one with a cut-off wheel and the other a flap wheel - and a welder is all it takes.

And you get to keep the tools! How cool is that?... and the 'payback' in terms of not forking your hard earned dollars to the knucklehead, is real quick.

MIG welder ( a decent one) - $500
Grinder #1 - a $12 Harbor Freight for cut-offs
Grinder #2 - a $75 DeWalt for flap wheels because it has good bearings
... +/- total, about $600.

2.5-inch, mandrel-bent tubing kit from Summit: $220 (even less if you buy only the pieces you need)

Knucklehead: $350 to $400 for crushed 2.5-inch tubing so it's really only 2.25 inches. Boooo!!!!

.. see how that works?

 

I can cut it, I just want a OEM as close to it as possible setup. Cutting and welding no problem. Where did you find it?


Its a 1973, nothing like old iron

 

Since you don't want that crackly noise, just stay away from the Glass Packs, and you'll be better off.

I went to Walker Exhaust's website and they only listed the 155" wheelbase. I then went to Rockauto and they listed the same Walker parts, all for the 155" wheelbase models. I couldn't find anyone that lists the exhaust crossover pipe, just muffler on back.

Muffler, you have a choice of three different Walker mufflers.
SoundFX P/N 18231
Premium Quiet Flow P/N 22000
Heavy Duty P/N 22583

 

Ok thanks I'll look them up.

 

What is the difference between a 2 and 4bl front Y pipe? 360-390 FE

 

You can build your own y pipe as well, Walker sells ball sockets that will fit the oulets of the manifolds. Look at the exhaust you have now and measure. Buy yourself bends that are the close to the same angles and start tacking things together. Mandrel bent exhaust will flow 33% more than crimp bent exhaust, easy performance gain. I did this on my Tacoma, followed the stock routing and used a chambered Magnaflow that was actually bigger than the stock muffler. I upsized my pipe so I can actually hear what my engine is doing. The Magnaflow isn't obnoxious with just a slight rumble at idle and at normal cruise speed is actually close to silent. A good chambered muffler is what you are looking for.
