GR86 Performance Panel Filters

I’ve got a K&N panel filter in the GR86 and have noticed zero difference over the OEM filter, whether that be performance or noise - which can’t be heard over the Cobra exhaust anyway! 😆.
I only keep it in as it’s paid for but swap it back to the OEM one come service time, so as I get a new one… 😉

Im tempted to go old school and put a playing card in the wheels, get some real noise out of the thing! 😁

The front pipe has a GPF in it not another cat, you will likely throw the CEL up and it wont pass an MOT.

I think the part I was thinking of was the 'sub muffler' in attached diagram, I dont 'think' there are any sensors there or further back?

MOT wise I've 2 years before that and then would swap the OEM item back in for the day.

(also realise this now should be in the exhaust thread! :) )

1. Manifold and 3. Front pipe is a bit of a no go. 2. Overpipe 4. Midpipe/centrepipe and 5. Axleback parts are all bueno.

it has been proven in many tests over the years that a brand new OEM Paper filter will flow better than any aftermarket panel filter. Only after a certain usage will the OEM start to loose out to the aftermarket filter.

Do you know what the part number for the OEM filter is by any chance?
