rams horns

I have late 60's and want to find out where or who makes the flange and exhaust pipe. I will be welding up my own pipes but napa wants $85 just for a set of flanges and a short pipe that is crimped to fit the exhaust header, No donut.
Anyone know?

Not sure what you're asking about a ram's horns set of flanges. You have ram horn manifolds no? Meethinks you just need about $10 worth of crap for that. I'll look at a set of those hangin on the wall in the a.m.

Yes. I have rams horns and want to get to exhaust pipe . Need the three hole flange ,donut and some pipe to get started.
Napa does not carry this item even for the OEM.
However they can get me a stub pipe that is crimped like a donut and fits into the manifold and supply a flange . But cripes $84 bucks sound rediculuse!

Most any muffler shop worth their salt should be able to fix you up for a lot less than $85 I would think.

The swagged collector and donut at a muffler shop should be about $25 for both sides, including a foot of pipe.

alittle1, u were right. 2 donuts,2flanges and 2 flared stubs $29 at a good midas and a good exhaust man. Took longer to price it then it took to make 'cause they don.t usually do little jobs like that.

How close is the angle of the Rams Horn pipe outlet to the angle of the original exhaust manifold? I would like to put a set of 2 1/2" Rams Horns on my '75 pickup (SBC 350) , but I'm not sure how difficult it will be to route the down pipes.

In general, I have quite a bit of room in the engine compartment, but I have to work around all the 4WD components (axle, and transfer case mounts) when I route the pipes.

Thanks,

Bruce

On 4X4 Blazers & Pickup up to 72 the left/driver side goes straight down and the right/pass side is at @45* angle. Not sure if 75 would be different. Bolt pattern at front may be different like here. http://www.chevytech.com/3c10o9.html

Here's a few manifolds>.

The engine in my truck is a GMPP 350 that is about five years old, and I think the bolt pattern will work fine with either type of manifold. I have to take a look at the angle my current manifolds and see if they are similar to the angles on the Rams Horn. The manifolds I found in the parts catalog are for a Corvette with 2 1/2" exhaust, not the more common 2" Rams Horns that were used on GM trucks and small block cars.

I think they will fit, but getting header pipes bent by a muffler shop is hard to do if I have to have the manifolds mounted on the engine first. Once they are mounted (at home), I have no exhaust until I get to the shop. The cops may not really like the sound of a 350 with no exhaust.

Thanks,

Bruce

If you have some mufflers or maybe a couple of 2.5"x90* mandrel bends in the back, they might actually believe you're heading for a muffler shop. The first time, anyway.

45 degree rams horn availablility

I have the same 45 degree 2" rams horns fitted to my 49 F-1 with a 350. I am going to have to go down the same path but I want it in stainless. I can't use the straight dump rams horns due to a clearance problem with the pinion shaft into the jag rack. I am set up with a Jag XJ IFS. Does anyone know if the 45 degree rams horns were other than the 2" ones that I have? (i.e.
2 1/2"?)

Corvette's use 2 1/2" up until 1982 if your still looking for a larger set.
Most roundy round guys use them for the flow.
