Our Texas Speed & Performance long tube headers for 1997-04 C5 & Z06 Corvettes are built from high-quality 304 stainless steel. They feature 1-3/4" primary tubes with 3" collectors, and they are mandrel-bent on a CNC mandrel bender for 100% ensured accuracy. We offer a 3" x-pipe system for both off-road and catted setups! When combined with our TSP 3" off-road x-pipe, up to 20-25 rear-wheel horsepower gains can be seen! Our 3" off-road x-pipe is 304 stainless steel, and our 3" catted x-pipe is 409 stainless steel with 3" bullet-style catalytic converters for maximum flow and performance.
We will include a pair of GM MLS exhaust gaskets, as well as the necessary clamps, to complete the installation. A pair of plug-and-play O2 extensions are now included in this package for no additional charge! Tuning will also be required with any long tube header system to turn the rear O2 sensors off to avoid any "service engine soon" lights. We do offer mail-order tuning services for those that do not have a tuner local to them.
The headers are designed to be a slip-fit connection with both x-pipe systems and will bolt up to most axle-back exhaust systems on the market. The 1997-2000 vehicles will require a 2001-2004 oil dipstick, tube, and bolt, and this is what we include in the kit for the 1997-2000 vehicles. If you have a 2001-2004 car, you will not need these items because your car came from the factory with them. You can also complete your header and x-pipe installation with a set of Stage 8 locking header bolts!
TSP 97-00 C5 Corvette Stainless Steel Long Tube Headers
This will include the TSP 1 3/4" race-style long tube headers only! It will not come with O2 extensions, oil dipstick and tube, or x-pipe. However, it WILL include the off-road connection pipes to connect to your factory H-pipe. You must add the other items via the drop-down menu or purchase one of the other packages if you are needing any additional items with the headers.
The connection pipes will come standard with the headers and will allow you to fit the headers to your factory H-pipe. It will require you to cut the front portion of your factory H-pipe off in order to clamp the connection pipes in place.
This header package will include new Cometic exhaust manifold gaskets, (2) 2.5", and (2) 3" band clamps to complete the installation. The 1997-2000 vehicles will require a new oil dipstick, tube, and bolt for this installation, and these items will automatically be included. You will need to have your computer tuned to turn off the rear O2 sensors since they will be removed for installation. If the ECM is not tuned for the rear O2 sensors, you will have a "service engine soon" light. The front O2 sensor harnesses will have to be extended to accommodate the new location of the O2 bung on the long tube headers. You have the option of including these plug-and-play harness extensions with your order.
