Question. Do M8s and TCs have different exhaust port angles. Friend wants to know if the header pipe from one will fit the other.
No one else put you on the road you're on. It's your own asphalt.

The spread is different.
Ignorance is bliss, and accuracy expensive. How much of either can you afford?

By spread I'm assuming you mean the distance between the exhaust ports is different?

Yes- the port pieces (nuts, clamps, gaskets, flanges) are the same. The distance is different.

Do you have a measurement for the difference?

Top pipe is M8, lower pipe is TC.
!/2" difference inside to inside.

A man with a cutoff wheel and a welder can fix that for you.
