PURCHASE DISCLAIMER: RR Racing does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. RR Racing will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

This product is a mid-pipe section exhaust that fits with Lexus GSF muffler.

Please note that the photo of the mid-section does not reflect the mid-section we ship now. Our new mid-section has an H pipe instead of the shown Y pipe. This was done to improve fitment.

Our GSF mid-pipe 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.

Power gains are similar compared to most 2.5” dual cat-less GS F exhausts, or about 20hp 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!

We strongly urge you to check your local laws as removal of catalytic converters may not be allowed in your state.
