no problem or trouble at all man.. it's in my car so i can just take as many photo as i want...
the under carriage photos was taken during my visit to a tyre shop to fit my rear ARB as well as tyre allignment.
what's the different? design different, finishing different. WiSE 4-2-1 has an equal length for all the piping coming out of the engine (the "4" portion), and it's not chromed. HB 4-2-1 has a shorter piping length at the "4" portion for cylinder 2 and 3, and it's chrome-finished.
I dunno, maybe someone can explain: i thought the extractor should be of equal length but why HB extractor has shorter length for cylinder 2 and 3?
