I'm changing my top boost 90 degree bend. I've got the 57-51mm reducer pipe.

I'm putting it onto the standard plastic 45 degree.

It keeps popping off since doing the egr delete.

All I need to know is what size coupler I need to go from the silicone 51mm to the plastic pipe.

Thanks

Best to replace the whole lot up to the egr delete, that way no more poxy couplers. Cheaper than another coupler too probably.
