Was wondering if all pipes with the same EFRA are =. Example the OS 2090 pipe and Alpha 2090 Pipe will the inner dimensions and performance be similar/ same.

If you look at the pipes they look different

From what I remember, OS's pipe numbers are not the EFRA numbers. For instance, the 2060 is actually EFRA2042.

But usually for other companies, the pipes would otherwise be identical. Like the Ofna 086, Dynamite 086 or Novarossi 9886. All the same.

Zoom in on the OS2090SC pipe and it appears the EFRA # is 2089, the number to the right of the big 2090 number. The 2090 designation is the OS part number not the EFRA number. These pipes are not the same as the Alpha where 2090 is the EFRA number.

Thanks I missed that one I have many 2060 and Mugen EFRA 2042 - same pipe didn't click.

The alpha pipe looks interesting was hoping they were the same due to cost looks like I have to spend the $$$.

Do you know if this pipe is a low or high end pipe seems to be a low-end pipe from its size and width.

The outside looks does not tell anything about the internal configuration. I know there are pipes looking the same on the outside but a different inside tuned to the specification.

Normally all different brands using the same EFRA number must be the same pipe because the EFRA number is an homologation number so the product can/may not be different than the homologated original.
