Borla S-Type Classic Cat-Back Exhaust System with 5-Inch Polished Tips (140165) - 2005-2006 Pontiac GTO 6.0L V8
Wake up the high-performance spirit of your muscle car with the high-impact Borla S-Type Classic Cat-Back Exhaust System. Custom-engineered exclusively for 2005 to 2006 Pontiac GTO models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the iconic S-Type Classic sound level. Formulated explicitly for driving enthusiasts and LS purists who crave a highly aggressive, race-inspired exhaust note under acceleration, this system is calibrated to give the massive 400-horsepower 6.0L LS2 V8 engine a bold, crisp, and high-impact growl. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily commuting, or spirited track runs.
The internal engineering of the Borla 140165 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a full dual 2.5-inch main pipe diameter. This system incorporates a proprietary Borla Merge X-Pipe that combines and smoothly blends the powerful V8 exhaust pulses, assisting in both sound attenuation and scavenging efficiency. This lightweight architecture optimizes airflow dynamics, flowing an incredible 200 CFM over the restrictive factory layout to release hidden horsepower, sharper throttle response, and torque across the entire powerband while shaving over 25 pounds of dead weight off the vehicle. Built completely from premium-grade, aerospace-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a distinctive dual split rear configuration featuring massive single 5-inch round, rolled edge angle-cut lined bright chrome on T-304 stainless steel tips. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla's legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the late-phase VZ-generation captive import Pontiac GTO platform equipped with the 6.0L LS2 V8 engine. It is fully compatible with both the Tremec 6-speed Manual and 4-speed Automatic transmissions and fits 2-Door Coupe Rear-Wheel Drive (RWD) models. It is designed to match the factory dual-exit rear bumper valance found on 2005-2006 models and will not natively align with the single-side exit bumper setup of the earlier 2004 5.7L LS1 models without rear valance modification.

Detailed Vehicle Fitment Breakdown
Compatible Model Years:
This system fits the following individual model years under the specific chassis, body, engine, and drivetrain constraints listed below: 2005, 2006 Pontiac GTO (VZ Platform Only).
Pontiac GTO Fitment Breakdown (6.0L LS2 V8 RWD):
Fits 2-Door Coupe models with Automatic or Manual Transmissions:
- 2005 Pontiac GTO: 6.0L LS2 V8 RWD (2-Door Coupe - *Split Rear Exit*)
- 2006 Pontiac GTO: 6.0L LS2 V8 RWD (2-Door Coupe - *Split Rear Exit*)
Important Application & Compatibility Notes:
- **Bumper Compatibility:** Engineered exclusively to route through the factory dual-exit bumper cutouts standard on 2005 and 2006 models.
- **Engine Restrictions:** Tailored strictly for the 6.0L LS2 V8 engine bay and mid-section layout. Will not directly bolt onto 2004 5.7L LS1 setups due to mid-pipe and hanger variances.
- **Premium Materials:** Built entirely with authentic T-304 stainless steel to deliver superior rust resistance over lower-grade T-400 series choices.
