Rattle after front pipe install - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Decimus · 01-24-2015, 05:45 PM

Just installed a tanabe front pipe but I hear slight rattling when I rev the car. Where could it cause this issue? I read about lifting the pipe and tightening?

One bolt from the over pipe snapped too but luckily I still had enough threads for replacement nut.

Edit: problem solved. Over pipe got slightly moved during install. Wiggling it around got it back to no rubbing the subframe

Could be the over pipe hitting the subframe?

Does it have a badge on it. My j2 downpipe had a badge it was rratteling cause the welds broke

Possibly, I searched more and I think maybe the over pipe is slightly misaligned so going to try to move it and tighten down the front pipe hangar bolt

Nah didn't have a badge. Good looking out though

Did you reuse the OEM dounut the slips on the downpipe? Forgetting that step caused a rattle in my car. Good luck!

Problem fixed! Went under the car again and loosened the front pipe hanger and trial & error until I found the "sweet spot" with no metal on metal. It was definitely the over pipe touching the sub frame. Thanks everyone!
