I've replace my stock CAC pipe with a Flow Pro CAC pipe. I've noticed that it's leaking where it hooks up on both ends of the pipe. I didn't replace the rubber coupling that mates the pieces together. What can I do to fix this issue, I'm afraid of over tightening the clamps and breaking something. Are there better after market rubber couplings that I can use or get new OEM ones? The ones that are on there now look like there in good shape. I noticed that it's always leaked a little on both ends of the CAC pipe prior to installing the new Flo Pro pipe. Also is the residue that is leaking out of the CAC pipe oil? Any advice or suggestions would greatly be appreciated. Thanks!
