When I took my exhaust manifold off I had bolts holding the down pipe to the manifolds on both sides. I notice in the assembly manual that OEM used studs/nuts on the drivers side and bolts on the passenger side for the GS and GS455. Interestingly, it is reversed for the Skylark 350. So, should I used bolts on both sides, studs/nuts on both sides, do like the assembly manual, or it doesn't matter? If I use studs should I go with the ARP stainless stud with their special nut? What say you???
