Texas Speed Long Tube LS1 Headers! The TSP 1 7/8" Long Tube headers are possibly the most powerful LS header available for the money! These headers offer gains of over 25rwhp!  This is the perfect header for anyone looking for a header with huge power potential!

.

• Manufactured using flash-controlled 16-gauge carbon steel tubing.
• Mandrel bent 1 7/8" primaries insure high exhaust flow rates.
• Steel head flanges are quality-manufactured to insure a precise fit.
• Welded O-ring port seals are milled flat to insure a leak-free installation.
• Collector design provides a smooth transition to your exhaust system.
• Ceramic coating provides years of trouble free performance with improved heat dissipation

Our headers are designed to accept our TSP 3" off-road y-pipe and TSP 3" catted y-pipe, along with our TSP 3" Rumbler X True Dual exhaust system!  All of them will be a slip-fit onto the header collectors.

***These headers will require O2 extensions, which are not included with the headers.  They can be purchased for an additional $40.  We also recommend using the GM MLS header gaskets and GM bolts.***
