OEM RS5 exhaust manifolds / catalytic converters, 40k miles, excellent condition!

[volvofan]

Had to do an engine-out job on my 2013 RS5 (broken flexplate). While it was out, we swapped these exhaust manifold / catalytic converters for a rare set of Kline headers I found. These headers/cats are in perfect working condition... I borescoped the cats and the honeycomb is completely intact and shows no signs of deterioration. Never had a check engine light for cats or o2 sensors at any point prior to removal.

Part numbers: 8T0253019E & 8T0253020E

Any chance these will bolt up to a lowly B8 S5 4.2 V8?

Maybe...... but why would you want to? The cats are separate from the manifolds on the S5 4.2, and you can simply replace them with test pipes. Any marginal gains from upgrading to these would probably be offset by the gigantic pain in the ass involved in dropping the motor.

Just thinking outside the box. 'Gigantic pain in the ass', not withstanding, you make a good point. Marginal gains on a motor that redlines ~1450 RPM lower than the RS5, so the benefit might not ever be realized anyway. It was a serious question though, but when you include the cost to have JHM work their magic, it's a $2000 set of headers! I guess I'll just move forward with the original plan, which includes the Race Pipes I received from JHM just this week!

Aha... I get ya. You were going to send these to JHM and get the catless ones for the RS5. Yeah, I dunno if they would mate up? I can't think of why they wouldn't, but given how Audi shoehorned these damn motors into the engine bays, something would likely interfere somewhere, somehow. Best to stick with the test pipes and call it good to go. Your butt dyno will not likely notice the difference (other than your wallet remaining considerably fatter!).

Good luck and have fun!

Do you happen to have the intermediary pipes from the exhaust? They are the pipes that bolt to the headers. Thanks.

I do… shoot me a PM if interested.

My apologies, they just sold yesterday and I forgot to update this listing. Thanks for your interest and good luck with your search!
