Dynomax Exhaust Intermediate Pipe

I installed factory tubular exhaust manifolds from a late eighties 5.0 Mustang onto an older F150 302. Making up my own dual exhaust for the project appeared to be a problem, none of the local pipe benders could make up the ball flange to hook to the manifolds. I found a pair of these Walker 41726 adapters at Advance at a great price. The fit of the pipe ball flange is very good against the manifold. I would prefer for the flange connector that the bolts go through to be concave instead of flat, but this is not a big issue especially since I could not find any other options besides this part. Well made part at a great price and they were shipped quickly. I also ordered part number 548755 Nickson 45 degree pipes to make the direction back correct. Overall I am very happy with the parts, I will be able to make up a dual exhaust system for a fraction of what the muffler shops would charge.

Went to muffler shop to have pieces bent and was told that the material was not aluminized as advertized. Also would not bent properly, material was too thin.

You will need two of these for a full system replacement, one before the muffler and one after it.

Worst in quality and I had to do the job twice because of this defective part. Don't buy and save yourself the headache.

To replace the complete system you will need 2 of these with the other components and one will have to be cut to length.
