Hello all,

Does anyone here know if for the Mk3 Cupra, the later exhaust backbox (290, 300 etc) is compatible with the earlier 280? I have a 2014 280 and previously opted for a backbox delete. Initially I thought it was great but over time, the drone, while not that bad has become a bit tiresome, especially for the wife, as it is a family car that we share.

I could go back to the original 280 back box but as I hear the later exhaust, from pre-facelift 290 onwards. was already a sort of "sports exhaust", I think this might be a decent compromise...especially as it's still a stock item, so I presume wouldn't have any drone at all.

They do look different however, so before buying, just want to confirm they are compatible....I assume so as I doubt SEAT would have changed something like this in between model years.

Appreciate any advice. Many thanks!

I thought the 280 stock system came with a resonator and additional silencer as well?

I have a 290 system like in your second link, and with a resonator delete it was the perfect balance. No drone, not too loud for early morning starts but had some sound to it when on the pipe and pops and crackled when in cupra mode off throttle.

I took mine off my 2015 pre facelift so it will definitely fit your 2014 280. Not sure where you're located but I'm selling mine as I've taken the engine from my cupra hatch and put it into an estate so the exhaust didn't fit.

I have the whole system from downpipe back available - resonator delete and backbox basically. Done 34,000 miles.

Hi @mjj4 - yes the stock 280 exhaust does have the additional silencer + resonator. These images were posted just to highlight the difference in the back boxes.

Interesting....how much are you selling it for? Do you have any pictures? I am based just north of London.

Btw, have just had a look through the thread covering your project. Wow, that's quite an undertaking!

Ah okay that makes sense!

I'll grab some pics of it for you. I'd sell the lot for £130 which would sort your exhaust from your downpipe back. It's a Zaustworx resonator delete 63mm.

Give me a couple of days to get some pics if it's of any interest.

Yes, please do share some pics. Whereabouts are you located? As that will also influence whether I can come or not. Cheers.

I'm based in Swindon Wiltshire if that's any good? Didn't get into the garage over the weekend as was doing house renovation bits, but if you're still interested let me know!

Location wise is okay. Only thing that is giving me pause for thought however is that you said it also has res delete....I'm after a stock 290/300 system.
