3” OUTBACK EXHAUST SYSTEM to suit NISSAN NAVARA STX550 3.0L V6 2010 – 2015 (CAT BACK)

Description

Overview

The 3″ exhaust for Nissan Navara STX550 3.0L 2010–2015 Cat Back system from Outback Exhausts improves flow, sharpens throttle response and produces a tougher V6 exhaust note. It is specifically designed for the STX550 V9X turbo-diesel and replaces the factory system from the diesel oxidation converter rearward while still retaining all factory emissions equipment. Made in Australia from 409 stainless steel, it provides strong durability for touring, towing and off-road use in harsh local conditions.

Because the system uses the original mounting points, this Nissan Navara STX550 3.0L cat back exhaust bolts straight up with no welding required. The mandrel-bent 76 mm tubing maintains smooth gas flow, which helps the turbo respond faster and generates a deeper, more refined tone without excessive drone. As a result, it suits daily-driven work utes as well as heavily loaded touring rigs.

Delivery & Lead Times

This Nissan Navara STX550 3.0L cat back exhaust is supplied to order. Lead times vary depending on Outback Exhausts’ stock levels and current workshop demand. As a general guide, Australian-wide supply falls within standard freight timeframes once the order ships. Regional or remote areas may take slightly longer.
