180 degree headers for GM LSx V8 engines swapped into Porsche 996 and 997 chassis. Fully tested and ready to ship. These headers come with all header tubes, head flanges, ARP head bolts, and collectors, ready to bolt onto your LS based engine such as LS1, LS2, and LS3. The end of the collector is ready for your new tubing or a connection piece like a v-band clamp. V-band clamps and other connections are optional and can be added to the order, just ask us. These headers are 2 pieces with expanded tube connections underneath the oil pan for expansion and contraction during heat cycling and for ease of installation and removal. USA made by a US veteran. CNC bent and TIG welded construction, no corners are cut during design and fabrication - these are the headers you want! Again, these come with collectors, 100% welded, ready for the rest of your exhaust to be built or you can order the remaining pieces through Duke Engineering Solutions for a 100% bolt-in solution to your Porsche 996 and 997 LSx Swap. The hard part is done!

Primaries are equally timed and 1.875" diameter - no other options available at the moment but we are open to custom builds. Collectors transition up to 3" at the exit. These are USA made with USA 321 stainless steel with thick flanges at the head. We designed these headers to work with factory A/C packages and sensors using ICT billet low alternator mount and factory LS water pumps. We have confirmed early LS1 Corvette/Camaro and later LS3 Corvette/Camaro AC compressors clear the headers with factory mounts.

NOTE: You will need to run a Canton LS1 15-276 front sump oil pan or similar to give these headers room to clear the pan and below the engine. You will also need an LS3 Camaro starter or PowerMaster 9509 for clearance. V-band clamps, mufflers, 180 bends, and J-bent tubes not included but can be for an additional cost. Price includes shipping in the lower 48 states of the USA - orders placed for Hawaii, Alaska, and International Sales are subject to cancellation. If you live in these areas and want to order, please contact us directly as your shipping prices are much higher.

Please contact us if you have a custom need. Thanks for looking!
