Velcro works tooI have the Opt7 Auro Smart-LED Strip kit (4 strips), purchased on Amazon here. I installed the kit using guidance found on here the CivicX forums and also on YouTube. Warning about the YouTube video - it has some good camera angles and lighting (which is why I found it helpful) but do not puncture your seats. It's not necessary. The method of ziptie-to-frame under the rear seats works just fine. Oh, and I used the fuse-tap that came with the Opt7 kit, hooking up to the ACC fuse.
Not the best quality picture, but here's an idea of what they look like:
I'm putting in a new diffuser and muffler. I'm having a shop run and Weld the pipes together. I'll have the pipes ran like the white civic, only I'll have the tips come out the cutouts in new diffuser.if you dont have the double exhaust pipe i wouldnt touch that...you will have a hole on one side
the tips looks really nice...but you would have to get the exhaust tip to flow straighter to look good...cause as it is with the angle that the car have it would look way out of place...
hope this can help
