RR Racing Tune Options for Lexus GSF/RCF
This is the best value Performance Power Package on the market for Lexus GSF! It combines the famous RR Racing Bazooka Exhaust with RR Racing PPE Racing Headers with optional RR Racing tune for optimum normally aspirated power. The power gain with the tune is expected to be between 40 and over 50whp (depending on options, fuel, etc.) as shown in the dyno chart below.
Tuning is critical to optimize power gains with headers and exhaust. We offer various tuning options with this package (see options for this product) as follows:
The RR Racing Valvetronic Bazooka Exhaust:
- For RCF models 2018 and newer we offer to swap your ECU with 2017 ECU. This is necessary as we cannot tune the newer ECUs, but we have successfully performed the ECU swaps with earlier models.
- Tuning physical ECU. You can ship us your ECU for us to tune. We will email you ECU removal instructions. For more information about this tune, please refer to GSF ECU Tune
- Remote Tuning. We can ship you our remote tuning kit on-loan (price includes refundable $550 deposit for the kit). We send detailed tuning instructions and links to remote tuning drivers and software that will need to be downloaded to your Windows computer. For more information about this tune and associated benefits and risks, please refer to GSF Remote ECU Tune.
This product is a full cat-back system, but it is also available in as an axle back bolt-on to Borla exhaust system for the RC F.
In “Bazooka” mode, our RCF Valvetronic Exhaust is race-car loud, bringing out the full sonorous glory of the RCF v8. The sound is absolutely addictive, much like the popular Borla exhaust, only louder. But as amazing as that sound is, we fully realize that there are times where a more civilized exhaust note is required, so we implemented 2 electronic valves that route the exhaust gases through secondary mufflers. With a push of a button on the remote control key fob, your RCF will go from race car loud to quiet and drone-free in just a few seconds.
Our Valvetronic Bazooka features high quality stainless steel construction with 2.5” diameter T304 stainless steel piping, X-pipe for better exhaust scavenging and maximum hp gains, and is 100% made in the USA. Our standard quad tips are 3.5” diameter carbon fiber, and are removable/replaceable in case of damage.
Power gains are the similar compared to most 2.5” dual cat-less RCF exhausts, or about 25hp measured at the wheels. Additional gains are attainable when pairing this exhaust with PPE headers and our ECU tune, or even our 670hp Supercharger kit!

PPE Racing Headers:
The PPE RCF/GSF Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 4-1 parallel merge collector. Completely TIG welded construction with thick 16-gauge tubing for long lasting power gains.We do not offer the PPE Equal Length headers for this package, as they do not add more power and the sound differences are minor with our exhaust system. However, if you are interested in PPE Equal Length headers, please contact us for package pricing. Please note that the headers do not come with manifold gaskets. For older cars replacing manifold gaskets may be necessary. We offer these as one of the options with this product.
These headers do not require a re-location bracket.
