Hey guys. I have a 2009 V8 R8. I recently installed the rev 9 exhaust. Today my EPC and check engine light came on. I’ve read something about an exhaust hose coming disconnected. Where is this? I also didn’t do anything with those two hoses that connected to the exhaust valves. Could that be an issue?

It could be many things and may or may not be connected to your exhaust fit
I had these come on & it was a failing lambda probe
You need to go back to where the exhaust was fitted firstly, if they are trustworthy and it was ther fault you'll save a load of money that way
I don't know if your system is valved etc. Connectors may be behind the bumper which is c. 90 mins to take off & the same to put on again so expensive if you're paying
