It is faster and hp is up ~150 at the wheels. I did full exhaust as well. With the double pane windows in my F-Sport the drone is noticeable but the music drowns it out nicely.
May I ask what exhaust you installed and would you recommend it?

PPE headers, Invidia mid and Tanabe Medallion. So far I recommend it. I just got the car back and took it to Lexus for some warranty work and troubleshooting an electrical issue. As soon as I get it back I will do some driveway videos at cruising speed and WOT (don't worry you won't need subtitles).

I was quoted roughly $10k for the entire install by RRR. I want to finish up my remaining projects before I drop the cash. Hopefully I can get some tips from you on what to expect. Do update your thread with the latest dynos and whether you are getting close to the 445whp stage 3 number.

It's funny, 10K is both excellent value and quite steep, depending on how you look at it. When new, jumping up the engine options costs this much, with the jump to the v8 being tens of thousands, so a bargain from this perspective. On the other side, I can get an entire LS V8 motor delivered my side of the world for much less than 10K.

I would have thought a bimodal exhaust was essential for such an epic undertaking...no one wants to hear a lexus drone but when she needs to breathe, she needs to breathe!

The amount of custom worked need to fit a LS V8, will blow will blow your budget past 10k.

I'm starting to see GS 350's in the high teens, low 20's. At this price super charger make sense.

I'm not refering to fitting it in the GS. It's just crazy that I can buy a whole engine for a fraction of the upgrade cost. In my dollars it costs an extra $60000 to go from the superb 3.5L Fsport V6 to the 5L V8, keeping in mind that almost every factory option in the US is fitted as standard here in both variants. For reference, an LS3 costs 10K delivered retail.

My point is that 10 odd thousand for the power of the 60K upgrade is a pretty good option if one ever considered the GS F.

My dealership sent me a recent offer stating that they'll give me $16,031 for my 2013 GS (with 56k miles) if I trade it in toward a 2019 GS 350..I would have to give them my current car and about $43,000 (includes tax) to get into a new 2019 GS 350. I see that a decent 2016 V8 GS F will run roughly about the same as a brand new GS350 in the neighborhood of $50k to $55k (https://www.autotrader.com/cars-for-...ngId=501708703).

But seeing as how the trade in value on the 2013's is under $20k, supercharging your current AWD version for $10k is a steal compared to trying to get into a GS F. But as you said, looking at it from the opposite perspective, you're spending 50% of the value of your car to supercharge it which seems pricey as well!

Does anyone know if supercharging voids the Certified or Factory warranties since its an engine modification?

I have little doubt that it voids my engine warranty. My four-year warranty expires this month anyway. Having gotten embarrassed by a 2.0T Audi when I was driving an S5 with a V8, i just don’t know if NA engines are the way to go up here in Colorado. The few times I flogged the S.C. equipped GS I am pretty sure I will not have issues with little turbo-4s any longer.

Yup. In the dealer's eyes, you can't possibly modify a car any more than putting in a supercharger! To them, that's like gutting the internals of a human body!

I would expect that any failure involving the engine, transmission, driveshafts, differentials, or otherwise "power-train" related will be voided.

Of course it does. So make sure your car is well vetted before pressing the button. Unless you're on a CPO or extended, the warranty is usually done in 50K
anyways, which on these cars is "just broken in".

Even lowering your ride on coilovers/springs voids your warranty. LOL.

Soooo.....Supercharge it, blow the engine, remove the supercharger and then shrug at the Lexus Service Department saying IDK what happened but my power train warranty is still good right??
