VRSF Catless Downpipe Gen2
What is this beast?
Welcome to Gapplebee's, where you'll be serving the gap sauce all day long! The VRSF Catless Downpipe for the Gen2 B58 is a massive 4.5-inch 304-grade stainless steel pipe that deletes the incredibly dense factory catalytic converter entirely. This leaves a straight-through exit path for your exhaust gases. Zero resistance, zero limits. Bolt this up to your A90 Supra or M340i, and your car turns into a fire-breathing demon. It is loud, obnoxious, and tells the whole block you are not here to play games. Send it!
Why the stock part is absolute pain
The B58 TU turbo is significantly larger and more capable than the Gen1 turbo, but it's choked by an incredibly dense factory cat. Freeing up the exhaust path with a catless downpipe unlocks massive mid-range torque and drastically drops your Exhaust Gas Temperatures (EGT). The turbo spools almost instantly. Yes, you need a tune to eliminate the Check Engine Light, but the horsepower gains and the violent exhaust pops are absolutely worth it. No mames, it's mandatory for Stage 2.
