RR Racing Tune Options for 2022 Lexus IS500
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:
- For IS500 Models 2022 - 2024
- You will receive a tuning kit with an OBD Cable and PC Dongle. A Windows Laptop and Wifi is needed.
The RR Racing Valvetronic Bazooka Exhaust:
This product is a full cat-back system. In “Bazooka” mode, our IS500 Valvetronic Exhaust is race-car loud, bringing out the full sonorous glory of the IS500 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 when 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 IS500 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 IS500 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 Headers W/ EPA Catalytic Converters:
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.
Equipped with 4" inlet/outlet Gen 2 G-SPORT 400CPSI catalytic converters.
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.
