My 23 comp is set to begin production but dealer is saying he’s still not able to add MPE yet. Says this COULD change anytime though, but not certain
So IF for whatever I can’t get the MPE but still want to improve sound somewhat economically and without adverse end of lease turn in consequence, what option makes most sense?

Delete resonator with x pipe. Turn in as is? Put resonator back on? Do they care either way whether new part or signs of removal and reinstall of original ?

Secondary cat delete. Same 3 questions above?

Downpipes. Reverse and sell at turn in?

New exhaust. Leave on or keep old, sale aftermarket, reinstall original?

Other???

Like any aftermarket part. Put on whatever you want. And just put it back to oem before return. Only genuine MP parts will the dealer not care if you want to just leave them on.

So make sure the exhaust shop doesn't throw it away.

You could also probably get away with a resonator delete without the dealer noticing too

I would recommend something bolt-on.
So you can always take it off, resell it, and return the car with no hassle.

With that saying, any axle back or cat back exhaust system, with or without secondary cat delete.
