The Texas Speed 1-7/8" Long Tube Headers with 3" Catted Y-Pipe is a complete header and Y-pipe package for the 1998 to 2002 LS1 Chevrolet Camaro and Pontiac Firebird and Trans Am. The headers are built from seamless 16-gauge 304 stainless steel with mandrel-bent 1-7/8" primaries, a velocity spike in the collector and welded O-ring port seals machined flat for a leak-free seal at the head. Texas Speed reports gains of 25 or more rear-wheel horsepower in applicable combinations.
The 3" stainless catted Y-pipe uses mandrel bends and high-flow bullet-style catalytic converters, and it slips onto the header collectors with the included clamps, two of which are band clamps for a tighter seal at the collector. New MLS exhaust gaskets and two O2 sensor extensions round out the kit. Actual gains depend on the engine combination, supporting modifications, exhaust configuration and tuning.

FAQ
What vehicles do the Texas Speed 1-7/8" LS1 headers with catted Y-pipe fit?
This kit fits the 1998 to 2002 Chevrolet Camaro and Pontiac Firebird and Trans Am equipped with the 5.7L LS1 V8. It is not for the V6 F-body cars.

How much power do these LS1 long tube headers add?
Texas Speed testing has shown gains of 25 or more rear-wheel horsepower in applicable combinations. Actual results vary with the engine combination, supporting modifications, exhaust configuration and tuning.
How does the Y-pipe connect to the headers?
Texas Speed exhaust components for these headers use a slip-fit connection at the header collectors. The Y-pipe is secured with the supplied clamps, including two band clamps for a better seal at the collector joint.
Can I use a different Texas Speed Y-pipe or exhaust with these headers?
Yes. Texas Speed lists the 3" off-road Y-pipe, the 3" catted Y-pipe and the 3" Rumbler X true dual exhaust system as compatible with these headers, all using the same slip-fit collector connection.
Are these LS1 headers and catted Y-pipe street legal?
No. Even with the catted Y-pipe, this Texas Speed header kit is sold for competition use only. It is not CARB exempt and is not legal for use on pollution-controlled vehicles driven on public roads.
