Product details

Product Overview

The Drift Spec Stainless Steel Catback Exhaust replaces your restrictive factory exhaust system from the catalytic converter back. It improves exhaust gas flow, reducing backpressure so your VQ35DE engine breathes more efficiently. The result is quicker throttle response, stronger mid-range torque, and a noticeably deeper exhaust tone. Designed as a direct bolt-on for 2003–2008 Nissan 350Z and Infiniti G35 models, it requires no cutting or welding for installation.

Ideal For

  • Daily Driving: Delivers a refined deep tone at idle and cruise that won't drone on the highway, making it comfortable for commuting.
  • Engine Performance Upgrades: Serves as an excellent foundation for further VQ35DE modifications — pairs well with intakes, headers, and tuning for maximum gains.

Troubleshooting and Problem Solving

Common Issues After Installation

  • Exhaust Leaks at Flanges
  • Rattling or Vibration Noise (hanger misalignment)
  • Excessive Drone at Certain RPM
  • Check Engine Light (rare on catback-only installs)
  • Tip Positioning / Clearance Issues

Error Code Solutions

  • P0420: Catalyst System Efficiency Below Threshold (Bank 1) — Most commonly caused by upstream catalytic converter issues, not the catback itself. Verify the O2 sensor downstream of the cat is properly connected and not damaged during install.
  • P0430: Catalyst System Efficiency Below Threshold (Bank 2) — Same as P0420, applies to Bank 2. Inspect both downstream O2 sensor connections and wiring.
  • P0136 / P0156: O2 Sensor Circuit Malfunction (Bank 1/2 Sensor 2) — Check that downstream O2 sensors were reconnected properly and wiring is not pinched or damaged.

How to Reset Check Engine Light After Installation

  1. Ensure the ignition is in the OFF position.
  2. Locate your vehicle's OBD-II diagnostic port (under the driver-side dash).
  3. Plug in an OBD-II scanner and turn the ignition to the ON position (do not start the engine).
  4. Select "Clear Codes" or "Reset DTCs" on the scanner.
  5. Start the engine and verify the CEL is off. If it returns, diagnose the underlying issue before clearing again.

What to Do If Your Vehicle Loses Power After Installation

  • Double-check all flange connections — an exhaust leak before the O2 sensors can cause incorrect fuel trims and power loss.
  • Verify the downstream O2 sensors are fully seated and connected (unplugged sensors trigger a rich/lean condition).
  • Inspect for crushed or kinked exhaust piping that could create unexpected restriction.
  • Confirm the exhaust hangers are not pulling the system out of alignment and causing binding.
  • If the issue persists, run an OBD-II scan for stored trouble codes to identify the root cause.

Long-Term Maintenance Tips

  • Regular Inspection: Every 5,000–10,000 miles — inspect all flange connections for leaks, check hangers and rubber isolators for wear, and verify tip clearance.
  • Surface Cleaning: Every 3–6 months — clean the polished stainless steel tip with a dedicated metal polish to maintain shine and prevent road grime buildup.
  • Hardware Check: Every 10,000 miles — re-torque all exhaust flange bolts to manufacturer specifications, especially after track days or aggressive driving.
  • Silencer Maintenance: Inspect the removable silencer periodically for carbon buildup; clean with solvent if exhaust flow becomes restricted.
  • Hanger Replacement: Replace worn rubber exhaust hangers at the first sign of cracking or excessive play to prevent rattling and stress on piping.
  • Warranty Reminder: Following these maintenance guidelines will keep your 1 Year Limited Warranty valid.

What is a catback exhaust?

A catback exhaust system replaces the portion of your exhaust from the catalytic converter to the rear tip. It improves flow, sound, and power without altering emissions-critical components upstream of the cats.

How does a catback exhaust work?

By replacing restrictive factory piping with larger-diameter, smooth mandrel-bent tubing, a catback reduces backpressure. This lets exhaust gases exit more freely, improving engine efficiency and unlocking horsepower and torque.

What are the benefits of a catback exhaust?

The main benefits are increased horsepower and torque (typically 10–15 hp on VQ35DE), improved throttle response, a deeper and more aggressive exhaust note, and better long-term durability with stainless steel construction.

Will a catback exhaust void my warranty?

A catback exhaust alone does not void your vehicle's warranty under the Magnuson-Moss Warranty Act. The dealer must prove the exhaust caused a specific failure to deny warranty coverage.

Is a catback exhaust legal in my state?

Catback exhaust systems are legal in most US states since they sit downstream of catalytic converters and do not affect emissions. However, some states have noise ordinances — check your local laws regarding exhaust sound levels.

Do I need a tuner for a catback exhaust?

No, a tune is not required for a catback-only install on the VQ35DE. The stock ECU will adapt to the improved flow. However, pairing with a tune will maximize horsepower gains.

How much horsepower does a catback exhaust add?

On a stock Nissan 350Z or Infiniti G35 with the VQ35DE engine, expect an average gain of 10–15 horsepower at the wheels, with the biggest improvements in the mid-to-high RPM range.

How much MPG gain can I expect from a catback exhaust?

Mileage gains are typically minimal — most drivers see 0–2 mpg improvement at steady highway cruise. The primary benefit is performance and sound, not fuel economy.

How long does it take to install a catback exhaust?

A professional shop can typically complete the install in 1–2 hours. DIY installation in a home garage with basic tools usually takes 2–3 hours, depending on the condition of factory bolts.

Can I install a catback exhaust myself?

Yes, with basic mechanical skill and the right tools (jack stands, socket set, torque wrench) most enthusiasts can install a catback at home. Rusted factory bolts are the most common complication — penetrating oil helps.

How often should I maintain my catback exhaust?

We recommend a visual inspection every 5,000–10,000 miles. Re-torque flange bolts every 10,000 miles and clean the polished tip regularly to preserve the finish.

Will this catback exhaust fit my 2006 Nissan 350Z with VQ35DE?

Yes, this Drift Spec catback is designed as a direct bolt-on fit for all 2003–2008 Nissan 350Z and Infiniti G35 models with the 3.5L VQ35DE V6 engine. Send us your VIN for 100% confirmation.

What is the warranty on this catback exhaust?

This exhaust comes with a 1 Year Limited Warranty against manufacturing defects, covering issues like weld failures, material defects, and fitment problems when installed correctly.

Do you offer technical support?

Absolutely. Our dedicated support team is available at service@egrperformance.com for fitment questions, installation guidance, and troubleshooting both before and after your purchase.

How long does shipping take?

Orders ship from our USA warehouse. Most domestic orders arrive within 3–7 business days depending on your location. Expedited shipping options are available at checkout.

Can I return this catback exhaust if it doesn't fit?

Yes, we accept returns of unused, uninstalled products in their original packaging within the standard return window. We strongly recommend verifying fitment with your VIN before ordering to avoid return shipping costs.
