Hey guys,

I tried searching this. I recently installed Full Ark grip exhaust on my g37 coupe.

The directions stated "may need to re-tighten bolts over time"

I was wondering how often do you have to re-tighten the exhaust bolts, has anyone had to re-tighten their bolts. To give a timeline, it has approximately been 3-4 weeks since my installation.

 

The heat from the exhaust causes it to expand and contract.

you usually only need to tighten them again one more time. (after 3-4 weeks is fine)
