Folks, I have a 52 F1 with a stock v8 flathead. I'm trying to make somewhat of a daily driver out of it. I need a full exhaust. My manifolds are in good shape. I thought about just making a custom exhaust using the manifolds , for a cheap dual exhaust option. I have some cash on hand I obviously cold use the money elsewhere on the truck. However I do need exhaust to get it inspected. I see Reds headers has a full exhaust system for $400 or so, that's not a bad deal. I figure I'd have about $100-$200 in my homemade job.

I guess my questions is, are headers worth the time trouble and money involved for a basically stock flathead? This is no show truck, just a driver. hate the thought of snapping off a manifold bolt. I've had headers on vehicles before, very few were worth the trouble I had with them, leaks, heat, rusting etc... on the other side I don;t want to toss out performance I could gain with headers or money I'd be waisting replacing my manifolds down the road..

thoughts/input?

It just depends on what you want and what you are willing to deal with.

I personally have no use for headers on anything except a race car unless it is to fit an engine into something that manifolds just won't work on.
Everything about headers is a pain and not worth it on a driver.

Extra heat in the engine compartment.
Starter and other items hard to get to.
Plug wire problems.
Exhaust leaks to deal with.
Clearance issues.

Just my opinion. YMMV

I've run Red's nickle plated tube headers on my 48 for the past 10 years - same headers on a daily driver. I've had none of the issues Richard listed... 'course I don't have high temperature issues in Montana.

The headers that Red's sell actually FIT the F1-F6 series trucks and are made specifically for them.

That said, there are minimal hp advantages to running headers on a stock engine. If you have good manifolds use them. Mine were cracked and the engine was out of the truck on the floor making replacement easy.

In your situation, I'd spend the money on something else. Just my dos pesos.

 

If you have a good exhaust manifold, I'd use it and save the money for something else...If it's not broke.....

 

Ditto MT's comments. I bought them because they sound nice!

 

I am not 100% if they are reds but I have some headers on my flathead and love them. I have super simple exhaust. Its headers to 2" pipes into glass packs that dump out right before the rear axle. Nothing fancy but sounds great and it was on there before I got it. Daily driven since march.

 

I have dual exhaust using stock manifolds on my '48 panels without a problem. The set up was on the chassis when I bought it. Since the chassis was a pickup chassis I had to reroute the exhaust around my gas tank. I haven't noticed any problems and they sound nice, the glass packs are finally starting to burn out.

 

This is a topic I'm also interested in for my new 1950 F1 Stake. It has the stock single exhaust now, but I want dual exhaust. I have looked for a supplier of pipes for the stock manifolds but so far have not found any. Is custom pipes the only answer?

 

I think so. I thought I knew of at least one supplier. I see Mac's has parts for an original (tail, crossover)

My exhaust needs 2 repairs , I may just fix that and go, or If I cannot get something else, I may have to run the Reds. Mostly for cost, and just sell the manifolds.

 

Unless I was going gennie, I'd never consider stock exhaust manifolds. Yes, the exhaust manifold is just a single component of the entire breathing system but manifolds of that era were mostly about clearance and cost, not efficiency.

A good flowing exhaust with a bump or two of the jetting is almost always a good thing

Just my .02

 

I thought I update this. I did end up going with Reds headers. I did not buy the complete kit, mostly because the shipping was $100! I bought their headers and extensions along with a set of 26" smithy's I gave them a quick coat of heat paint and installed them tonight. Instead of full tailpipes I plan to run 90's off the muffler and excite right in front of the rear tires. If I hate it I can alway's order the tailpipes... I originally planned to just use the manifolds but after looking at a custom exhaust or making my own I thought this was the better option.

My manifolds are in excellent shape and all the bolts came off except one. I spent a good amount of time after I twisted off the head. I had several attempts of welding on a nut with no success at first. I finally bumped up the wire to .35 and the bolt got cherry red and finally came loose...

I do like the Reds headers and extensions. They fit well. My only issue would be they fit real loose and you need to crank on the pipes to get them to seal. Only an problem is you want to tear down the system.

getting close

 

You won't be disappointed! That's exactly the system I have, except for the side dumps (I'm going to get tailpipes soon).

I agree about the loose fit; I'm thinking of having the muffler shop put flanges at the joints (so they'd both slip on and bolt together), because I hate how muffler clamps crush the ends.
