Pops and bangs. Think my cat is dying.

[hoggaz]

When hoofing it I hear a popping noise. Sounds abit like its back firing but it isn't very loud and seems to be popping a few times, not just one bang. Usually happens around 6k rpm. Does this sound like a cat issue and the car will fail its mot test on emissions next month right?

 

[Maxx]

Sounds like either that cat or over fuelling but im no expert :/ wish my exhuast popped etc tho and I have a de-cat!!

popping is gr8 !!! ... enjoy it

Doesn't sound like the usual overrun or when decelerating through the gears where it is common to get pops.

 

[cliokiz]

Love popping my valver kicks out some tasty flames!

Is it performing normally other than this?

 

[hoggaz]

Yeah, it performs fine. With the mot test next month I think I'm just gonna try and get hold of a 172 cat cos I'd cry if it failed on emissions :dapprove:

Exhaust on my Cooper S likes popping and crackling. Enjoy it mate.

 

[hoggaz]

Yeah but I can't really enjoy it if my car is off the road Gonna see if I can get a cat converter.
