  • Price
    $5,500
    • OBO
  • Location South Orange, NJ, 07079, USA
  • Condition Used
Description:

Up for sale is a Kline exhaust off of my 991.2 TTS. I'm being told it's inconel (came with the car when I got it a few years back, part number is pictured). It sounds great, but decided I wanted a bit more sound from my setup. Comes with 2 cats, and also the gaskets -- you may want to grab new ones for peace of mind. 

It's slightly dented on the bottom (scraped during tow truck dropoff when I got the car) but confirmed with Kline themselves it was ok. No leaks or changes in sound, purely cosmetic. 

I do have a short sound clip I can provide upon request!

$5500 SHIPPED (US only) obo. Located in Northern NJ. Would love to get this giant box out of the house!!

Are those high flow cats or factory? Sound clip would be great if you can post it?

Hey! Cats are aftermarket from Kline.

Hopefully the video link works. It was a cold start so I only revved it to like 3k or so. Mainly just to show it's no rattles or weird sounds.

One side of the cat goes to the turbo, one side goes to the exhaust -- the cats just aren't both sitting on the same side in the closeup pic. (See the very 1st pic...they are sitting the same way in that one).

Another bump, still accepting reasonable offers. Absolutely nothing wrong with it besides some surface level scuffs that you won't see unless you're under the car!!

More pics available upon request. Would like it gone as soon as possible as it's a massive package sitting in my guest room --
