Performance Exhaust Systems — Price Comparison

Performance Exhaust Systems for 2021 Nissan Frontier

A cat-back exhaust changes how a 2021 Nissan Frontier sounds more than how fast it goes — and that's the honest pitch. Material, muffler design, and tip styling separate the tiers; actual power gains on an otherwise stock engine are usually single digits.

We compared 3 offers across major retailers for the 2nd Gen platform (2005–2021 2nd Gen). Prices range from $899.99 to $1299.99 as of the last update.

Best picks

• Best overall: A 304 stainless cat-back from an established brand with a documented sound profile — drone at highway cruise is the most common regret, so check in-cabin clips, not just fly-by videos.
• Best budget: An aluminized-steel system. It sounds nearly identical but trades corrosion life — fine in dry climates, shorter-lived where roads are salted.

What to look for

• Axle-back swaps are cheaper and reversible; cat-back systems change more of the note.
• 304 stainless outlasts 409 and aluminized steel significantly in winter-salt states.
• Resonator deletes amplify drone on long drives — listen to interior recordings first.

Truck-specific note: cab configuration and bed length change part fitment more than model year does. A crew cab with the short bed and an extended cab with the long bed are effectively different vehicles to parts catalogs — have your exact configuration handy when ordering.
