my cars are euro cars...so i have dual single down pipes off euro logs currently
the parts i have is just the 4 tri y headers and the 2 down pipes
i paused my trip to the coaters....my mechanic wants me to have a machine shop smoothen the ends of the headers where they meet the block to make sure there is a tight fit
also to have the egr hole plugged with welds
If I may suggest, rather than plugging the egr holes with weld, have a block off plate done with new gasket (as per picture attached).
