I recently bought one the HKS downpipe flanges because I've been wanting to go catless. I understand how to remove like the air cleaner box itself, but rerouting the vacuum lines has me very confused. I've tried reading through the forums to find pictures, but majority of the links are dead. Could someone explain or send a diagram of where to reroute all of the vacuum lines when removing the secondary air cleaner and EGR? Thanks in advanced.

Evening everyone, I'm a returning member from back around 05-06. I had a VG flatsider that was towed away by an HOA when I was deployed. Anyway, I'm back and looking for another flatty and catching up with things.

I've searched here every way I can think of and I can't find the fairly recent post someone made about how they repaired the little "bumps" that appear on the 88/89 front seat bottom cushions. I remember it had something to do with a plastic piece under the cushion that maybe the stitching was attached to. Can whomever posted it link me to the post? Thanks! Mark

I tried to post this in the proper section but it won't let me. I'd like a little quieter exhaust than what came on my car, which appears to be a 3" Magnaflow. What are some good options that are currently available? A friend said not to go bigger than 2.5" to get sufficient backpressure. Is that correct for these cars? Thanks, Mark
