I can not decide of which exhaust to go with

[jboogie1289]

I wonder is there really a difference between the double x corsa sells vs a regular xpipe. Do you have any videos of your setup?
I just bought corsa active axlebacks! Going to see how I like it with stock resonator. If not loud enough, Ill do a resonated xpipe first then maybe xpipe with bottle style resonators.

I have some videos but they are too large to post. I’ve even cut them down in to smaller segments to try and get them uploaded but that still doesn’t work either. I think i recorded in to High of Resolution. Only a couple of pics of the car on the lift before the Post Startup.

Check Signature link for my for Borla S Type Catback which came with a Merge X-Pipe. Sounds perfect to me. Bought from Lethal Performance .

See pic https://www.borla.com/products/ford-mustang-gt-cat-back-exhaust-system-140960 and sound clips there. Appears to have shorts barrels in pipes like a resonator but description doesn't say.

Founds these comments on Reddit:

Hi, just chiming in! The Ford Performance systems we make for Ford are a little different from our standard Borla systems. The S-Type is going to be a bit more aggressive than the Sport. In addition, the Borla Cat-Back has a dual 3" diameter, whereas the Ford Performance is dual 2.5".

Aggressive in term of being louder than Sport? If so would Ford Performance extreme be equal in volume with Borla S- type ?

The Ford Performance Extreme would still be more aggressive/louder than our S-Type. Our ATAK sound level will be more aggressive than Extreme.

Thank you for answering my questions. I think the S type would be perfect!

A Merge X-Pipe is a specialized type of exhaust crossover component that combines elements of an X-Pipe design with a merge collector, aiming to optimize exhaust flow and performance in a dual exhaust system. Like a standard X-Pipe, it features two pipes that intersect in an "X" shape, allowing exhaust gases from each bank of a V-engine (e.g., V6 or V8) to merge. However, what sets the Merge X-Pipe apart is its incorporation of a merge collector—a tapered or contoured section where the two pipes converge into a single outlet before splitting back into two pipes. This design enhances exhaust scavenging and velocity, potentially boosting engine efficiency and power output.

How It Differs from a Standard X-Pipe

A standard X-Pipe simply crosses two exhaust pipes at an intersection, merging the exhaust pulses from both engine banks to equalize pressure and improve flow. It excels at reducing backpressure and enhancing high-RPM performance, often producing a higher-pitched, raspier exhaust note. However, its flow dynamics can be less refined because the gases collide directly at the crossover point, which may not maximize velocity or scavenging efficiency.

The Merge X-Pipe refines this concept by adding a merge collector at the intersection. This collector smooths the transition of exhaust gases, reducing turbulence and increasing the speed of the exhaust flow as it exits the crossover. Think of it like a funnel: the gases are compressed into a narrower section before expanding again, leveraging the Venturi effect to pull exhaust out of the cylinders more effectively. This can lead to better mid-range and high-end power compared to a standard X-Pipe, while still maintaining the smoother flow benefits over a straight dual setup.

How It Differs from an H-Pipe

An H-Pipe, by contrast, connects two parallel exhaust pipes with a perpendicular crossover tube, forming an "H" shape. It balances pressure between the two banks but doesn’t merge the flows as fully as an X-Pipe or Merge X-Pipe. The H-Pipe’s design creates more backpressure than an X-Pipe, which can enhance low-end torque but may limit top-end power. Its exhaust note is typically deeper and more traditional, akin to a classic muscle car rumble, due to less aggressive scavenging and frequency cancellation.

The Merge X-Pipe differs significantly from the H-Pipe in its flow characteristics. While the H-Pipe relies on a simple tube to link the pipes—requiring exhaust gases to make sharp 90-degree turns—the Merge X-Pipe’s "X" intersection and merge collector provide a more direct, linear path. This reduces resistance and enhances scavenging, much like a standard X-Pipe, but the collector takes it a step further by optimizing gas velocity. As a result, a Merge X-Pipe typically offers a performance edge over an H-Pipe, especially at higher RPMs, and a sound that’s raspier and more refined than the H-Pipe’s bass-heavy tone.

Key Differences Summary

• Flow Design: Merge X-Pipe uses a merge collector for smoother, faster gas flow; standard X-Pipe merges directly without a collector; H-Pipe links pipes with a basic crossover.
• Performance: Merge X-Pipe often outperforms both, with better scavenging and velocity for mid-to-high RPM gains; X-Pipe favors high-end power; H-Pipe boosts low-end torque.
• Sound: Merge X-Pipe leans toward a crisp, high-pitched tone (like an X-Pipe but potentially smoother); X-Pipe is raspy; H-Pipe is deep and rumbly.
• Complexity: Merge X-Pipe is more intricate and potentially costlier to manufacture or install than a standard X-Pipe or H-Pipe.

In practice, a Merge X-Pipe is often marketed by performance exhaust brands (e.g., Flowmaster’s Scavenger series or Magnaflow) as a premium option for enthusiasts seeking maximum efficiency and a unique sound profile. It’s particularly suited for high-performance applications where every bit of horsepower matters, though its benefits might be subtle on a stock or mildly modified engine compared to a well-tuned X-Pipe or H-Pipe.

TLDR Section:

If You Want Maximum Performance (High RPM Power)

• Recommendation: Merge X-Pipe
• Why: The merge collector optimizes exhaust scavenging and velocity, making it ideal for high-performance builds, especially on V6 or V8 engines in sports cars or race applications (e.g., Mustang GT, Camaro SS, or modified trucks). It shines at higher RPMs, potentially adding a few extra horsepower over a standard X-Pipe. Brands like Magnaflow or Borla offer Merge X-Pipe designs that are well-regarded.
• Best For: Enthusiasts with tuned engines, aftermarket headers, or track-focused setups who want a crisp, aggressive exhaust note.

If You Want a Balance of Performance and Simplicity

• Recommendation: Standard X-Pipe
• Why: It’s a proven design that reduces backpressure and boosts high-end power without the added complexity (or cost) of a Merge X-Pipe. It’s easier to find and install, with a raspy, high-pitched tone that’s popular in muscle cars and street builds. Flowmaster and Corsa make solid options.
• Best For: Street-driven cars (e.g., Charger, Challenger, or F-150) where you want improved flow and sound without over-engineering the exhaust.

If You Want Low-End Torque and a Classic Sound

• Recommendation: H-Pipe
• Why: The H-Pipe enhances low-RPM torque, making it great for daily drivers, heavy vehicles, or setups where you’re not chasing peak horsepower (e.g., classic muscle cars like a Chevelle or towing-focused trucks). It delivers that deep, throaty rumble reminiscent of old-school V8s. Look at Pypes or Dynomax for affordable, effective H-Pipes.
• Best For: Cruisers, stock engines, or anyone prioritizing a traditional exhaust growl over top-end performance.

I have some videos but they are too large to post. I’ve even cut them down in to smaller segments to try and get them uploaded but that still doesn’t work either. I think i recorded in to High of Resolution. Only a couple of pics of the car on the lift before the Post Startup.

So I just installed the corsa axlebacks. Honestly, sounds somewhat similar to stock active axlebacks. Im looking to add an xpipe with two bottle style resonators to tone it down a little or just do a resonated xpipe. Cant decided which

Is that so? They advertise no drone. I had borla on my v6 s550 and it didn't drone at all. So that surprises me.
I have seen people say corsa handles interior noise and drone better than borla.

I had Borla Atak catback on my s650 GT no drone in highway no cabin noise at all. If you got active exhaust helps in early morning or late night start ups.

Upload them to YouTube and then post the link here

Yeah, I did the X-Pipe first and it sounded good with the Factory exhaust but I wanted more. And I got just that with the addition of the Corsa Exhaust. Not hating it and despite what some say about the X-Pipe, I love the sounds and “Rasp” (as they claim)!!

 

[Cabotmustang]

I have the Steeda H pipe with active exhaust and like it. However I am looking to add a bit more rumble and down between Corsa Extreme and Ford Performance Extreme now.

I personally like x over H. H sounds off to me. To me, an xpipe has a smoother tone to it even if its "raspier". But I plan on adding steeda xpipe with two bottle resonators. If that is too loud for me, Ill probably do resonated xpipe.
