Anyone tell their insurance company their car is modified?

Not necessarily.
A well running RB with a cat will pass the e-test.

You have to remember, these motors came stock in something, and at one point did run properly, but in most cases still do.

true they came stock in alotta cars but not ours so wouldn’t all the specs be all fucked and not to mention the readings, how would u get around that? wanna do some engine work but shit like that worries me
