Re: Exhaust manifold temps different?
Is this in the drive way on muffs? Are you talking about the risers? If so thyey do run diffent temps. 100 degrees seems excessive. Maybe you have a restriction in your exhaust manifold or riser. Take it off and see if all water passages are open. I had a 50 degree difference on mine and had a severe restriction on my one riser. change manifolds and risers now temps are within about 15 degrees of each other. just my 2 cents.
