Hey guys I was previously running the stock exhaust manifold on my 9. I am upgrading to an ETS tubular. Every picture I see online of guys running aftermarket manifolds also all seem to have new high temp radiator hoses. It it necessary or can I get away with running the stock ones?

 

I've run an OEM rad hose with multiple tubular manifolds, never had an issue, though I've never had one touching either, just make sure it doesn't touch and you'll be fine

 

Thanks a bunch. Should save me some money. Not a fan of buying expensive unnecessary parts.

 

If your worried about it you can always wrap it in some kevlar.

 

Definitely do not need to upgrade. OEM hose will work with a plethora of tubular manifolds.
