Can a 91 exhaust manifold fit a 87 13b? need to know asap please guys

- i need to get my car inspected need info?

 

bump

 

yes

 

thanks

 

Im getting a 91 stock manifold tomorrow. wil the O2 senor on the 91 manifold be any different from my 87 base model? will the S4 senor fit onto the 91(S5)exhaust manifold with any problems? does the Exhaust manifold from the S5 fit the S4 motor? need info because im going for inspection on tuesday. my manifold has a crack and wont pass.

 

Exhaust manifolds are completely interchangable in every way between s4 and s5. There are some slight differences, but nothing as far as how they bolt up, etc.
