I just installed an OBX Header on my 2001 altima GXE and it sounds and smells like it has an exhaust leak. I am using the header and downpipe with the stock muffler and cat. I tightened down all the bolts real good. I heard that i need to torque down the header bolts in a certain pattern, is this true? Please help me!

You remember the header gasket? How about the donut gasket?

did you torque them from the middle out? some of the smell may be the coating burning off...
since this thread is over a week old, how are they doing now?
