Exhaust rattle on cold start? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

As the title says.. Exhaust rattles on a cold start up and RPMs around 2-3 k... anyone else noticing the same thing?

Will have to get it up on a lift and check all the bolts are tight on the exhaust system... just wondering if this is "normal"

Hi, did you find anything?
I too have some rattle on cold start that sounds like a cracked manifold.
I have a stock exhaust end-to-end
Thanks!

had this issue on several cars in the past... typical problem is the heat shield on the catalytic converter will rattle when cold, and get better on warm up. The shields start to fail/rust at some junction. May not be your issue, but have observed it in the past. It only get's worse over time. Other areas to look at are exhaust system joints.

You just made my list! No warnings for you, straight to a citation for any infractions you incur.
You better live in the moment and be careful about delving into the past in here from here on out!

OK, but, how far do you go back?
