I've been looking around for a set of upper ic piping to go with my spearco fmic that will allow me to retain the stock air bypass. I find numerous kits in 2.5", but theyre all generic bends. Majority of the kits I come across have some type of open atmosphere bov. I have the Bosch 110 on the way and would like to retain the use of that. If anyone knows where I can get just upper ic piping(fender to tb) I would greatly appreciate it. I'm trying to avoid eBay if possible.
