Does anyone know what the back pressure should be on a X16XEL?
Not a lot. Look for foreign objects in the exhaust if you're having trouble.
Also inspect the cat. I've seen them dislodge and nearly block off the exhaust completely..
How does 5psi sound? ok?
Sounds high to be honest!
But I've no idea what pressure it should be.
I'd have thought less than 1psi really.
I've just put a new middle pipe and back box on, and it's just the same. Is there anyway I can check to see if the cat's blocked? Don't really want to shell out on a new one if I don't have to! Does the TIS say what the back pressure should be?
phil had problem with his recently,tried everything turned out to be damaged valve iirc.here
