Show original supplier description
This upgrade is crucial for turbocharged vehicles, as it allows for faster and more efficient expulsion of exhaust gases. By reducing resistance, the turbos spool more rapidly, leading to increased power across the entire RPM range and the capability to support higher peak power levels. Additionally, faster heat evacuation contributes to lower engine temperatures. Constructed from durable 16-gauge T-304 stainless steel, these downpipes are precision TIG welded for superior quality and longevity. They are proudly made in the USA and feature a 200-cell count element, ensuring emissions compliance. The design allows for improved turbo response and reduced engine temperatures. This product is explicitly stated as NOT AVAILABLE FOR SALE IN THE STATE OF CALIFORNIA. The downpipes are designed to support up to 700 AWHP.
