Does anyone make an off the shelf 1 7/8" header for a RB in a A-Body (67-76)? or a 1 7/8" step to 2"
TTI only makes 1 3/4 then up to 2 inch. They don't make an 1 7/8 for a RB in an A body.Tti exhaust?
I have a RB in my 71 Demon and it has 2 inch TTI's. I'd go with the 1 3/4. You'll have more room..As TTI doesn't make an 1 7/8. I'd go with the 1 3/4. The 2 inch are very tight in an A body.Does anyone make an off the shelf 1 7/8" header for a RB in a A-Body (67-76)? or a 1 7/8" step to 2"
I have used both. Currently have 1 3/4" and sold the 2" as they were miserable to work with. They fit great once one, but man I hated those things. I think the 1 3/4" could be hurting my combo some so was trying to find something a little bigger. May just have to make a set myself, but not sure if I have the patience for that.I have a RB in my 71 Demon and it has 2 inch TTI's. I'd go with the 1 3/4.

I went with the 2 inch because I have a fairly healthy 440. If the car was street driven mostly I'd have gone with the 1 3/4..I have used both.

Drag Car onlyIs it primarily a street car?
Even if the 1 3/4" primary tube is less than ideal, it can support a lot of horsepower. How fast are you now and what does the car weigh? It might be easier to find the power somewhere else.

Then 2 inch may work better for you. But in running them you sacrifice space. But once they're installed and you know the process in working on your car with them on there it's not as bad.Been mid 10's at 3150 lbs.
The National Hemi Owners Association at one one time had access to 2" under chasis headers from Positive Performance Headers. The owner of PPH passed away and someone purchased his company. The headers require the water pump engine mounts. They will not work with stock mounts. My car was the original jig for these headers. In the mid 80's the NHOA purchased 100 sets

I had them in 2 inch on a 70 duster 440. There a good durable header as they were on for more than 30 years. Once on their easy to remove and install. KimNo love for the Pro Parts 2” headers?
I have a couple of customers with them...... they didn’t seem to have any real complaints.
I'd like to see what they look like installed.
That's close to what I have in my 2 inch TTI's..$1049
