Silverado 1500 Cat-Back Description
This 2014-2019 Silverado/Sierra 1500 cat-back exhaust system replaces the restrictive OEM section from the catalytic converter rearward, unlocking the airflow potential of the 4.3L V6 and 5.3L V8 EcoTec3 engines. Each kit is CNC mandrel-bent from 3-inch T304 stainless tubing, paired with a high-flow straight-through muffler and polished 4-inch slash-cut tips.
For B2B partners, the value goes beyond the part itself: every batch ships with QC inspection reports, lot numbers, and SKU labeling ready for your warehouse system. Buyers can request custom tip styles, branded packaging, or private-label muffler tuning — capabilities most aftermarket brands outsource. The result: faster turn time, higher margins, and zero fitment returns on Crew Cab 4WD and Double Cab 2WD/4WD trucks

FAQs
Q1: Will this fit a 2016 Silverado 1500 5.3L Crew Cab 4WD with the standard 6.5ft bed?
Yes — the kit is validated against all 2014-2019 Crew Cab 4WD wheelbases for the 5.3L V8.
Q2: Do you support OEM/private-label branding?
Yes. We provide laser-etched logos on muffler shells and tips, plus custom carton printing.
Q3: What’s the difference between the aluminized and T304 versions?
T304 stainless resists road-salt corrosion for 10+ years; aluminized steel cuts cost ~25% with a 3-5 year service window — ideal for warm-climate markets.
Q4: Can I order mixed cab configurations (Crew Cab + Double Cab) in one container?
Absolutely.
Q5: How do you handle DOT/CARB compliance for U.S. importers?
This is a cat-back (post-converter) system, so it’s 50-state legal as a performance replacement and does not require CARB EO numbers.
Q6: What’s the typical sample lead time?
About 35days.
