I recently got a set of Ash inlet pipes to go on my car. I noticed while inspecting them that the silicone couplers fit pretty loose on them. I thought it may have had something to due with the fact that the pipes do not have hose beads on them. Upon further inspection it looks like the pipes only measure 2 7/16" (roughly 60mm) at the ends. I was thinking about getting a set of 2.4" hose couplers to use so that I get a snug fit. The charge pipes are fine, likely due to the hose beads adding some girth to the pipe diameter. Anyone else have similar experience with these pipes? Any suggestions?
