Nissan GT-R (2009–2024) · Cat-back exhaust

Is a Cat-back exhaust Worth It on a Nissan GT-R?

Short answer · Depends

A cat-back replaces the exhaust from after the catalytic converter(s) back to the tips. It changes sound and can slightly change flow; it does not remove cats. For the 2009–2024 Nissan GT-R (R35 (2009–2024 US); multiple power bumps (Premium, Black Edition, Nismo, etc.)), Alone, power gains are usually small. Sound and weight are the main reasons people buy one. Pairing with a tune and other supporting mods is where numbers move more. Typical cost: Typical $500–$1,800. Difficulty: Moderate (jack stands, penetrating oil). A true cat-back keeps the catalytic converters, so emissions testing is usually unaffected—but loud systems can still break local noise rules. This page is general guidance—I am not claiming a personal install on every GT-R kit listed in search results.

Worth it if…

  • You understand this is primarily about sound/feel more than peak power on a stock tune
  • You will verify fitment for your exact GT-R before buying
  • You are willing to install carefully or pay a shop

Skip it if…

  • You expect guaranteed dyno numbers from a product page
  • You will not confirm generation-specific fitment
  • You are about to sell the car and want zero modification risk

Will it fit my car?

What it does

A cat-back replaces the exhaust from after the catalytic converter(s) back to the tips. It changes sound and can slightly change flow; it does not remove cats.

Typical gains (cautious)

Alone, power gains are usually small. Sound and weight are the main reasons people buy one. Pairing with a tune and other supporting mods is where numbers move more.

Fitment notes for the Nissan GT-R

R35 (2009–2024 US); multiple power bumps (Premium, Black Edition, Nismo, etc.). Transmission and boost control are sensitive—use GT-R specialists for tunes. Always match chassis code / generation—tuner catalogs often list sibling cars that look similar but use different brackets, MAF housings, or hangers.

Install difficulty

Moderate (jack stands, penetrating oil). Plan about 2–4 hours. Penetrating oil and proper jack stands matter more than the catalog photos.

Emissions / legal caution

A true cat-back keeps the catalytic converters, so emissions testing is usually unaffected—but loud systems can still break local noise rules.

FAQ

Does a cat-back exhaust add horsepower to a Nissan GT-R?

Usually little you can feel on a stock tune alone. Real gains tend to show up with a proper tune and supporting mods.

Is a cat-back exhaust hard to install on a GT-R?

Moderate (jack stands, penetrating oil). Budget about 2–4 hours. If you are not set up for DIY work, get a quote from a shop that knows this chassis.

Will this void my warranty?

In the US a modification alone does not void an entire vehicle warranty, but a dealer can deny a claim for a failure they can show the mod caused. Keep stock parts.

Did you test this exact kit?

Not as a blanket claim for every GT-R listing. This verdict is general, generation-aware guidance so you know what to verify before you buy.
