Does anyone know definitively whether the SMSP 4-1 header will clear the tranny to block brace without modifying? I know the 4-2-1 requires a little finessing but I'm not interested in that particular unit. This is for a track only ITR.

Thanks

 

go call SMSP.

 

Or pm him...

 

Already did and David wasn't quite sure about that aspect of the fitment, hence my question.

 

well, if you're referring to the 4-1 header where 4 tubes go side by side next to the oil pan, than NO, you can't fit the ITR engine stiffener.

 

From my understanding the multipiece doesn't need any modification and the 4-1 you can't use the tranny brace or the flywheel cover. I think the multipiece performs better too.
