For All You Haters That Say Intakes & Exhausts Don't Make Power - Dyno Proof

I'd hope so.

 

Hey guys,

Hey, Tuan here from R4T! The video we did highlights real-world testing, which is entirely separate from what K&N might control in their facility. The numbers we got were surprising, but knowing how turbo engines respond to simple modifications, the results weren’t entirely unexpected.

Another idea we’re considering is testing Mike's (LLOD) hybrid 2024 Tacoma with just the intake installed to see what kind of performance gains we can achieve. As mentioned in the video, most of the power gains come from the exhaust. The high price of our exhaust systems is mainly due to the premium stainless steel we use. The shop producing these systems for us also creates exhausts for supercars, so the quality and craftsmanship are top-notch.

That said, we’re exploring the option of producing a standard stainless steel version to reduce costs and make the exhausts more accessible. Performance would remain the same, which is what most people care about.

I’d love to hear your thoughts on this idea for a lower-cost, same-performance exhaust. Please @ me to share your feedback—I’d appreciate it!

 

Lower cost would be great . I certainly would have more interest.

 

$1800 (with the chrome/black tip) vs $1100 for the Magnaflow may be a tough sell. Not sure what the performance gains of the Magnaflow are. They say it's been dyno'd but don't give any numbers.

The TRD exhaust on my Tacoma is 12 years old and while it's not shiny, it's not rusty either. It's 409SS and that should be fine. I don't think even TRD Pros could be considered "supercars", so a supercar exhaust is overkill.

 

How do any of these other "performance" exhausts differ from the OEM pipe in terms of pipe diameters?

There's a TRD "center pipe" listed on the Toyota parts sites.

Of course nobody knows what it does or has any specs on it (thanks Toyota), but would it stand to reason that this might be like a down pipe?

Seems like a great gain could be had by opening up the pipe directly coming off of the Cat or maybe relocating the Cat?

 

I don’t think there are just haters on intakes and exhaust on stock tunes for no reason. Some haters, like myself, have some experience with past turbo models and mods on an OEM map.

Had a 2005 STI and 2009 WRX both modded and tuned many times, both in shop and road tuned.

What the Subaru forum members saw was aftermarket part manufacturer’s claim of dyno gains on CAIs and Catback exhausts without a tune came from pulls when the engine was running rich. Members found that once the engine was warm and started to lean, their dyno numbers had no gains and more knock and ping. Members found it critical to tune for true gains.

That was a decade ago.

Could it be true that a CAI and/or Catback can have safe gains without a tune in this 24 Taco when the ECU/ECM leans out? Yes, it could, but I’d be worried about it because we’ve been burned before.

The hate comes from a good warm fuzzy place. Lol
