Decat Catless Straight Downpipe Exhaust for 09-18 Nissan 370Z & 08-13 Infiniti G37

If you’re serious about performance, the Decat Catless Straight Downpipe Exhaust is your ticket to unlocking raw power. Built for the 2009-2018 Nissan 370Z and 2008-2013 Infiniti G37, this upgrade strips away restrictive factory parts to let your engine breathe freely. Whether you’re a car enthusiast chasing track times, a body shop offering custom builds, or a repair shop looking to upsell, this downpipe delivers results. Let’s break down why it’s a game-changer.

Why This Downpipe Stands Out
This isn’t just another exhaust part. The catless design means zero restrictions. Your engine gets cleaner airflow, which translates to instant horsepower and torque gains. Turbo models? You’ll love the faster spool times. Natural aspiration? Expect smoother power delivery. Plus, the aggressive exhaust note will turn heads without sounding obnoxious.

Key Features You’ll Love

• Premium T304 Stainless Steel: Rust and heat don’t stand a chance. This material lasts for years, even in harsh conditions.

• Mandrel-Bent Tubing: Smooth curves mean no airflow disruptions. Your engine stays efficient at high RPMs.

• Direct Bolt-On Design: No cutting or welding. Install it in 1-2 hours with basic tools.

• Universal Compatibility: Works with all engine types for the 370Z and G37, including turbo setups.

Why Go Catless?
Factory catalytic converters are like putting a pillow over your engine’s mouth. They trap exhaust gases, killing power. Removing them reduces backpressure, which lets your engine exhale freely. The result? More horsepower, quicker throttle response, and a louder, deeper exhaust tone. Turbocharged engines benefit even more—less backpressure means the turbo spins up faster, so you get boost sooner.

But Wait—Is It Legal?
Let’s keep it real. Catless downpipes aren’t street-legal everywhere. They’re designed for off-road or competition use. Always check local laws before installing. That said, for track days or show cars, this part is a no-brainer.

Built Tough for Nonstop Action
Performance means nothing without reliability. This downpipe uses T304 stainless steel, the same stuff found in high-end exhaust systems. It shrugs off road salt, heat cycles, and even minor impacts. The polished finish looks great, but it’s not just for show—it resists discoloration from extreme temps.

Mandrel-Bent vs. Crush-Bent: What’s the Difference?
Cheap exhausts use crush-bent tubing, which pinches the pipe during bending. This creates airflow bottlenecks. Mandrel-bent tubing keeps the diameter consistent, so exhaust gases flow smoothly. Think of it like drinking through a straw—no kinks, no struggle.

Who Needs This Downpipe?

• Car Enthusiasts: Boost your horsepower, sharpen your throttle, and enjoy that aggressive sound. Pair it with a tune for even bigger gains.

• Body Shops: Offer clients a premium upgrade that’s quick to install. Charge less labor, earn more profit.

• Repair Shops: Upsell to customers wanting more from their 370Z or G37. It’s an easy sell with instant results.
