Product Description



2001-2004 C5 Corvette & Z06 
Smooth Flow Exhaust Systems


These kits offer the hardcore driver an economical solution to get into a long tube header system without breaking the bank or skimping on quality.  100% Made In The USA!  

Our exclusive hand made long tube "Smooth Flow" design allows excellent scavenging properties. Optional ceramic coating inside and out typically reducing exterior temps by 60% extending engine component life and increasing horsepower. Constructed using 16Ga/.065 wall 1.750” primary tubes and 3” collectors while the Header flanges are 3/8” thick CNC cut for a precision fit. Headers are followed by optional 3” Hi-flo cats that transition into a 2 1/2" aluminized steel X-Pipe that will hook directly to the factory rear exhaust section. Simply the best header solution for the C5 Corvette.  *We will supply straight through pipe sections if you choose "No Cats".
