-issue: running airrex bags with accuair management, have had the VU4 manifold serviced twice already because some kind of material is getting lodged in exhaust ports of manifold. The only place the material can be coming from are the bags, checked for material substance, its a rubbery substance. brought the issue up a few folks familiar with airrex and air systems and said that it could be the bump stops deteriorating and when i air out the substance is getting lodged in the valves and keeping them open. the substance some are saying are the bumpstops deteriorating and coming through when airing out. my car when aired up will slowly start to airdown due to the exhaust ports sticking open. I was running UAS bags before and never had an issue, anyone else have this issue?
thanks guys, i am completely happy with my system. this issue just keeps arising and im without my car for about a week until my manifold is serviced by accuair.
