Can anyone tell me or have pictures of what all it takes to modify a S400 4.62" downpipe flange to a HX40 style?
Thank You!
Thank You!
The 4.62 is a much better flange with more sealing surface. What is the reason for the switch?
I am swapping to a larger housing, but the original used a hx40 style downpipe. I was trying to save some money on modifying the DP.
