Performance Exhaust (Cat-Back)

A cat-back performance exhaust frees exhaust flow with larger-diameter, mandrel-bent tubing, unlocking 5–15 HP on naturally aspirated engines and 10–30 HP on turbo platforms. This is 25–30% cheaper than a cold air intake (#1) for similar power gains on turbo cars, where reduced backpressure directly boosts turbine efficiency. On a stock 2.0T engine, dyno tests show a 22% rise in peak airflow versus the factory system.
