Just by looking at them (always dangerous), they look similar to the 5.7L Hemi Dodge Ram manifolds except that they are far more tubular.
The potential problem is where the collector is located, I BELIEVE (no proof) that the collector will hit the firewall of the car. I KNOW that the 2003-2008 5.7L Hemi manifolds off of a Dodge Ram will NOT work. The Dodge Ram collector points directly at the firewall with NO room to attach an exhaust pipe. The collector on these also appears to point directly to the rear of the motor, so I don't think they will work :(
Before I bought them I'd see what the return policy is, I'd hate to see you spend $125.00 on something that won't fit.
If you decide to pull the trigger, let us know if they fit. I plan on using TTI's headers but might use these to save $600.00.
