The short version: a cat-back exhaust is the mod you buy for the sound — the biggest tonal upgrade that’s still street-legal, because it leaves your catalytic converters in place. After weighing hundreds of owner reviews, our #1 pick is the Borla S-Type: aggressive on throttle, civilized at cruise, and built in bulletproof T-304 stainless with a lifetime warranty. Drive a lot of highway and dread drone? The MagnaFlow Touring is the drone-free champion. Want it loud? Borla ATAK. On a budget, the MagnaFlow Street Series is a proper stainless system for less.

How We Rank
Exhaust is subjective — one owner’s "perfect note" is another’s headache — so we rank by the collective verdict rather than a single opinion: aggregated owner ratings, review volume, and the themes owners repeat. We weigh four things. Sound — the tone on throttle, and just as important, whether it drones at highway cruise. Build quality — T-304 vs T-409 stainless, mandrel bends, and weld quality that decides whether it survives road salt for years. Fit — a true bolt-on with proper hangers and no rattles. And value, weighing sound-per-dollar and the warranty behind it. Prices were current at the time of writing.
The Exhausts, Reviewed
1. Borla S-Type — Best Overall
The one enthusiasts recommend without hesitation. Borla’s patented notched-tube tech gives it an aggressive, throaty tone on throttle that backs off to a livable hum at cruise, and the T-304 stainless is warrantied for life. Pros: superb sound balance, top-tier stainless, made in USA, Million Mile warranty. Cons: premium price, and it’s still noticeably louder than stock if you have neighbors.
2. MagnaFlow Touring Series — Best Drone-Free
The road-tripper’s exhaust. MagnaFlow’s Touring tuning deepens the note while keeping cruise drone to a minimum — the top choice for owners who log real highway miles. Pros: deeper tone, minimal drone, quality stainless, lifetime warranty. Cons: more subtle than aggressive, so sound-chasers may want more.
3. Borla ATAK — Best Aggressive Sound
Maximum attitude, still street-legal. Borla’s ATAK is its loudest tuning, delivering the wide-open race note enthusiasts chase while leaving the cats in place. Pros: the most aggressive sound here, race-bred flow, top stainless, lifetime warranty. Cons: most expensive, and the loudest — expect some cabin drone and attention.
4. MagnaFlow Street Series — Best Value
A proper mandrel-bent stainless MagnaFlow at a friendlier price. The Street Series tune is deeper and more aggressive than the Touring, making it a lot of exhaust for the money. Pros: great value, aggressive note, quality build, lifetime warranty. Cons: more drone than the Touring, and polished tips can discolor over time.
5. Borla Touring — Best Mild / Refined
Borla’s quietest, most refined tune. It improves sound and flow while staying subtle enough for a daily commute or a shared garage, with the same bulletproof T-304 stainless. Pros: smooth and drone-free, top stainless, lifetime warranty, daily-friendly. Cons: the mildest sound upgrade here, so it won’t satisfy owners who want to be heard.
How to Choose a Cat-Back Exhaust
Start with how loud you actually want it — and be honest about your commute. If you drive a lot of highway or share walls with neighbors, a Touring or S-Type tune that resists drone will make you far happier than the loudest race system. Next, check the material: T-304 stainless (Borla) resists rust and discoloration best, while T-409 is cheaper but ages faster in the salt belt. Confirm it’s a true direct-fit, bolt-on system for your exact year and engine so there’s no welding or trimming. Finally, weigh the warranty — a lifetime or Million Mile warranty tells you the maker trusts its own welds. And remember: a cat-back is a sound-and-character mod, so buy it for the note, not for horsepower.
The Verdict
For the best all-round cat-back, the Borla S-Type nails the balance of aggression and daily livability that most owners want. Log serious highway miles? The MagnaFlow Touring is the drone-free pick. Want it loud? Borla ATAK. On a budget, the MagnaFlow Street Series delivers real stainless quality for less. Check the current price on Amazon →
