🔧 Product Overview
Take your turbocharged 2.0L Lexus IS200T or IS300 to the next level with the SPDZ1 Race Downpipe — now delivered with a high-quality exhaust gasket included. Engineered for serious performance, this downpipe is built to reduce exhaust restriction, free up flow, and sharpen throttle response, especially when paired with a proper tuning solution.

💥 Performance Gains & Driving Feel
With the stock turbo, users often see gains in throttle response, especially in the midband, thanks to lower backpressure and more efficient exhaust gas evacuation. The SPDZ1’s design helps achieve:
Because our design doesn’t overly constrict the flow prematurely, your turbo can breathe more freely compared to many “budget” downpipes that taper too early.
