The Texas Speed 3.5" Cat-Back Exhaust System for 2014 and newer Chevrolet and GMC 1/2-ton trucks is a bolt-on 304 stainless steel system with a built-in 3.5" exhaust cutout. The cutout has a removable plate for manual operation, so the truck can run through the muffler for everyday driving or open the cutout for the most flow and the most aggressive sound. Texas Speed designed it for easy, bolt-on horsepower on the 5.3L and 6.2L trucks.
The entire system is 304 stainless and fully mandrel bent in 3.5" tubing, finished with a polished exhaust tip engraved with the TSP logo. Texas Speed publishes a few fitment notes: 5.3L trucks need a 3.5" clamp, and the system will only fit 5.3L trucks that already have the Texas Speed 6.2L LT headers and Y-pipe. Hanger modification may be required on Tahoe and Yukon applications.

FAQ
What trucks does the Texas Speed 3.5" cat-back fit?
Texas Speed lists it for 2014 and newer Chevrolet Silverado and GMC Sierra 1/2-ton trucks with the 5.3L or 6.2L, and its published fitment also covers the 2015 to 2018 Tahoe, Yukon and Suburban, where hanger modification may be required.
Will the 3.5" cat-back fit a 5.3L truck?
Only in one configuration. Texas Speed states the system will only fit 5.3L trucks that have the Texas Speed 6.2L LT headers and Y-pipe installed, and a 3.5" clamp is needed on 5.3L trucks. On a stock-exhaust 5.3L it will not connect.
How does the integrated exhaust cutout work?
The cutout is built into the 3.5" system and uses a removable plate for manual operation. With the plate installed the exhaust runs through the muffler; removing the plate opens the cutout for maximum flow and the most aggressive sound. There is no electric valve.
What is the system made from?
The Texas Speed 3.5" cat-back is 304 stainless steel with 100% mandrel-bent 3.5" tubing and a polished exhaust tip engraved with the TSP logo.
Is this cat-back street legal?
It is a cat-back system that installs behind the factory catalytic converters and does not change the emissions equipment, unlike a header or cat-delete. Opening the manual cutout bypasses the muffler, so check local noise regulations before running it open on the street.
