I had a resonated after market exhaust (Milltek) fitted about 6 months ago, and started hearing occasional dull popping/knocking noise when engine cold. Feels like the exhaust is getting slightly blocked then clearing itself.
The noise became a bit more frequent, until this morning when it just about stalled for a few seconds, felt like the exhaust was almost blocked - dropping the clutch and revving the engine seemed to clear it, and I parked it up shortly after.
Wondering if the secondary cat might have collapsed and be rattling around, and considering just taking into local kwikfit for them to have a look.
Anyone had anything similar?
