One of the collectors where it bolts to the manifold on the drivers side wasent bent just perfect it need to be bent a little further out. I jus got one side loosley bolted up and pried the other pipe over with a pry bar and it fell in to place. But that was just my issue dont know if you will have the same one i also heated upbthe pipe where the bend goes to the collector to let it flew a little better.
I had a buddy helping with my install. We just pulled on either end a little until they fit. Once it was close enough tightening the bolts did the rest of the work. Steve83 is right, be careful torquing on old exhaust manifolds, chances are they are already cracked.
Its not that difficult and you have to expect a little bit of work when buying mass produced aftermarket parts.
There was no way the magnaflow was gonna line up with my bassani headers. Took the bassanis off and put the stock monifolds back on. Left the drivers side manifold loose on the studs and tightened the ypipe to the manifolds. Tightened down the manifolds and all is good, no leaks!
Boo to having to put my bassani setup on the shelf though.
