Anytime you are installing a new component like a new larger turbo on your 03-05 Dodge SRT4, or a new header on your 95-05 Neon, you should consider installing ARP Exhaust studs.
Why ? Well, each time you remove and reinstall a screw into the head of your engine, you increase the chances of stripping out the threads, and furthermore the ARP studs are stronger! The ARP studs, because they are forged, can handle a lot more weight than your typical bolt!
The way these work, is you thread the studs into the head just like a normal exhaust bolt. You use a allen key to thread the stud into place as the stud has a allen key receptacle on the end of it. After tightening down the stud, you then put the new component onto the stud, and then torque down the nut onto the stud.
Heres a photo of a few of the ARP studs threaded into a head.
