im looking at the Humphries site for the Janspeed Cat-back exhaust.
I'm wanting a complete system that connects to the existing 1st cat through to the back box (without the 2nd cat.)
None of the items below seem to include the downpipe? Am I missing something?
So I have exchanged a few emails with Humphries and as far as I can tell they don't do a system which extends back from the K11 1st cat, excluding the 2nd cat.
So if I were to go for this Sportex and keep the 1st cat would the noise level be acceptable. i.e I could still have a conversation on the motorway and wouldn't scare babies
