Stainless Works Long Tube Header Kit (CTSVH) - 2004–2007 Cadillac CTS-V
Unleash serious performance gains from your first-generation Cadillac CTS-V with the Stainless Works Long Tube Header Kit. Designed to dramatically improve exhaust flow and power, these headers are proven to deliver substantial horsepower and torque gains while enhancing the aggressive sound of the LS-powered V-Series platform.
Featuring 1-3/4" mandrel-bent primary tubes feeding into 3" slip-fit collectors with an integrated merge spike, this long tube design maximizes scavenging and throttle response. Tested at Strope Speed Shop, a stock 2005 CTS-V equipped with Stainless Works headers, catback, and a tune gained an impressive 53 horsepower and 47 lb-ft of torque at the wheels. Constructed from corrosion-resistant 304 stainless steel and fully TIG welded in the USA, these headers are built to last and backed by a lifetime warranty. Note that high-flow catalytic converters are not included and are part of the Stainless Works exhaust system; some cutting and fabrication are required when connecting to non-Stainless Works exhausts.
