We carry a full line of Kook's long tube headers for both the LS1 and LT1 f-bodies. Kook's just released their LT1 long tubes, and they are available in 1 3/4" x 3", 1 3/4" x 1 7/8" x 3" stepped, and 1 3/4" x 1 7/8" x 3 1/2" stepped. These sizes can be bought with emissions provisions (Air and EGR fittings) or as a race header with just the O2 fittings. They are made of stainless steel, so you don't have to worry with any rusting! You can also purchase a 3" y-pipe with Magnaflo catalytic converters or a 3" off-road y-pipe. We are currently running a special on Kook's products, so give us a call or e-mail me at trevor@texas-speed.com for pricing.
