I appreciate your interest. I don't "see" any cracks or imperfections. However, the likelihood of there actually "being" zero cracks on a used VF39, is mighty slim. I didn't remove it because there was anything wrong with it. I replaced it with another VF39 that had Deadbolt waste gate area porting & black hole treatment. If I had mine done instead of buying one already done, I would have had to go a week with no car. Like I said there isn't really anything wrong with it but I haven't scanned it with an electron microscope, either. That is the reason why I prefer to do the sale locally/regionally so this can be a face to face transaction, where the buyer is free to inspect the unit before they pay.
if you have just some pics of the exhaust side and intake side ports i believe that would be enough info for me to check..i am really wanting to buy it..let me know..
