Fitting an Inconel exhaust to my Porsche GT3 997.2 - Kline Innovation

I fit a super lightweight Kline Innovation inconel exhaust to my 997.2 911 GT3. It doesn't exactly go to plan, but I get there in the end & now have what I think is one of the best sounding 997 GT3's out there!

I know we should be talking about how awesome the car sounds, but can we take a moment to appreciate the music that’s used in DW videos. Tracks are always pleasing on the ear and work really well with the content. Just feel that needs pointing out.. 😎

The sound is damn sexy. I got you very well about the straight pipe. It drives you mad and at the end It doesn´t sound really good. It´s just loud. The inconel exhaust system is what an engine like that really need. I like it.

[@jamest5149]

I believe Kline and Dundon make the best GT3 exhausts. I had k&n system, the same, just spent a bit of time sealing the airbox off as you mentioned... it’s open towards the rear/bumper and can take heat from the exhaust. I used a black plastic 5 litre oil bottle, I used roughly half the bottle side cut into an ‘L’ shape to wrap the bottom of the filter/airbox opening, was really easy and sealed it up nicely 👍 I was going to wrap in some heat protection tape but forgot and it didn’t deform or come to any harm after many trackdays in 40+ degrees in Ozz. Love how easy the GT3;s are to work on, they come apart so easily. Although I am surprised at the seized bolts you came across, Mine were like new, guess that’s UK salty, rainy roads compared to sunny dry, just dusty Oz.

[@driftworks]

And me. I love the Dundon headers, but wanted to keep the cats. Yeah I was thinking something similar on the K&N 👍

[@Trenchluv]

Sounds absolutely amazing! And I personally find the tip protruding appealing. (Initial setup was too much) but the revised center box and tips are spot on as they are but I can also see them being a slightly better fit if they were an inch shorter or so

[@1967Stotty]

997 GT3 is peak water cooled 911 IMO. That exhaust sounds simply incredible! Regarding headers... you should try removing them off a 996 with 177k miles on it. 20 hours labour to remove everything and fit new headers and back boxes (fortunately I had a fixed price agreed)... all bar 3 studs snapped... had to bring a specialist in with a jig to drill them out.

[@driftworks]

Haha, that sounds like a lot of fun!

[@mpwr321bhp]

Love the crackle on tick over, and on full chat, there are not many better noises that a flat 6, very impressive, looks cool too. Great seeing the slow undoing selection track, proper tool -> vice grips -> chisel -> heat -> grinder !!! The valve works really well, streetcar to a monster in a touch of a button.

[@lb9gta307]

3:08 I agree with all of this. I like stock exhaust and unsilenced intake for my daily and both an unsilenced intake and more agressive exhaust for my fun cars. It's super popular here to just do exhaust but I've never been a fan of that because almost sounds monotone IMO. Induction noises are much more dynamic to throttle position.

[@driftworks]

🤘

[@JD2ndcity]

It sounds incredible. I reckon a carbon heatshield to follow the exhaust cut out protruding out to the Kline logos 👌🏻

[@driftworks]

I did think about whether an extension could sort it. I think it's just too far though.

[@chrisg4rr377]

Seeing the fitment of the new tips I instantly thought get a carbon CSL splitter. Adding parts made of carbon makes the car weigh less too. Less weight = more race

[@driftworks]

Good logic.😄

[@TedTuned]

Lovely kit. Just on the exhaust manifold gasket, according to the likes of the legendary tuner A Graham Bell, a step up to the manifold is actually not a problem, in some cases it's considered a good thing. Helps with preventing gas reversion apparently. Another great warts and all video though. And that sound!!

[@driftworks]

👍 That''s the idea behind 'porting' the gasket, just incase there was any slight overlap on the head side. It means it only goes bigger into the manifold.

[@TedTuned]

@@driftworks aha, I thought from the Vid you were porting it out for the exhaust, not the head. I'll put my head back down below the parapet 😁

[@TL-Sneax]

Who remembers Phil's S14 kouki with the exhaust coming out from the side of the car? That thing was mental especially with Keith's Vertex kit.

[@Schnitzer325ci]

Phil seeking perfection as always. Wouldn't be Driftworks otherwise. Concerned the bumper might get burnt though, maybe that's the reason for it sitting out so far from oem?

[@driftworks]

It still runs cats and a standard tune, so it wouldn't get burnt or sooted 👍

[@christianfrorup1967]

Good job with the disassembly. Can't wait for the sound test and the Phil test.

[@evo80hd]

Ya that sounds amazing! I love the 997 GT3 and especially in Riviera blue! In case you haven’t tried it, the best penetrating fluid I have used, and I’ve used a lot, is the liquid wrench with Teflon. Also, if you don’t have any, you need nut extractors with the reverse teeth full stop!

[@KonspirAdy]

I had a GT3 fitted with a similar airbox & induction system, it lost over 20hp when tested back to back (Wayne Schofiled RR) with standard airbox containing a KN panel filter. Also had 4 different aftermarket exhaust systems fitted (SS & TI) off the shelf and custom made. All but one system again lost power over the OE exhaust fitted. I accept the weight loss gains though. All five of my GT3 over a fifteen year period were the Mezger versions, just sharing my experience.

[@driftworks]

Interesting! Were the exhausts using manifolds? Seat of the pants the car feels quicker with the exhaust. When it was on the 991 GT3 the difference felt more substantial. The K&N kit didn't seem to make much difference other than sound. (It's claimed to give about 12hp I think)

[@KonspirAdy]

Yes mixture of OE & equal length after market headers. The one that made an improvement was the Parr RSR long equal length primaries (non cat) single back box system, only downside is it blows 108db.

[@Triicks111]

i think that looks good like that to be fair, sounds insane 👍

[@driftworks]

Best sounding car in the world. My AWE system rear silencers looked the same (size and volume) but ran with out any side mufflers and long tube headers with cats more like Dundon then Kline.

Must be the massive heat cycles from track etc that does this to the bolts no, or the fact that its rear engined? I had virtually no issues removing a single bolt on my e36 m3 which is twice the age of this car! Anyways, lovely bit of kit!

The issue is all the crap the underbody aero and tyres kicks up there, and as you say the heat down there. Corrodes the metal like a salt spray would.

[@driftworks]

It is indeed! Yep they do.

[@idokwatcher2062]

Metal stretches when it gets hot too so they extend even further when car is driven. One of the reasons manufacturers align them with the bumper is so that you don't burn your leg when putting groceries in the trunk.
