For C7 we offer a second, more emissions friendly option aptly named our 1-3/4" Mid Length header system. Our Mid Length kit allows you to reuse the secondary set of factory cats combined with our "Severe Duty" 49 State Legal cats. Our objective with this system is to improve performance yet eliminate the possibility of an engine light (without a tune). The kit is a direct bolt-in made entirely in the US using 304 S/S throughout. Expect a quick and easy install with Grade 8 hardware and Flat Out Racing gaskets.  

Product features on ALL American Racing Headers systems include:

• 100% Made in the USA - Never Outsourced
• Made entirely of 304 stainless steel 
• 3/8" thick laser-cut flanges for a warp-free seal
• Hand-ported TIG welded inlets
• Optimized primary tube routing for superior fit and performance
• Merge collectors complete with welded scavenger spikes
• Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability
