I have both on my car and they are different in shape and size.
NHRA will not accept the IHRA sticker and IHRA will not accept the NHRA sticker when going through tech.
Each are marked with IHRA or NHRA respectively.
Each time my car was certified they looked at it closely and sonic tested for tubing thickness and each tube was checked for size.
Both are good for 3 years at a time but they are different even though both IHRA and NHRA use the same specs for the cert. it looks like to me.
