The Resonance Free Pipe (RFP) takes the place of a traditional resonator with much less weight and bulk. Some vehicle applications however still use resonators. An RFP works by venting a small amount of gas through the mesh in the pipe to break up standing waves which cause resonance in longer pipe sections. One tuning valve is used on the 5.3L L84 and two tuning valves are used on the 6.2L L87.

Just for your information: it’s an empty pipe, which has holes to break the pipe resonances (standing acoustic waves within the pipe). The patches are for reducing the generation of further noise

Any way to cut weight.  It is way behind the cab so no issues there.  Just wonder if you can hear a hissing sound coming from them at all?

Good info, thanks for the input. It’s stuff like this that I normally don’t even pay attention to.

I have the new Denali 6.2 what you think I will gain if I delete them.?

Nothing.  The fact that they let the exhaust flow out to me would seem that it doesn't make a difference. It still allows the exhaust to flow more freely than a traditional resonator.  No back pressure.

Yes if you weld them up or cut them off the sound will be louder.

No.  Works for drone/resonance elimination.  Change the muffler out.  That will get you more sound.

GM does offer a "performance" exhaust for the T1

I saw it listed on the build site as an option.

If you want to see what happens when you get rid of them, just cover them with exhaust tape or something.  It's far enough back where it shouldn't get too hot and even if it only lasts a while you will know what the effects are.  

 

That took some r&d to figure out.  I don't think positive things will cone from removing them.

      2027 GMC Sierra: Official Discussion

      By Jus Cruisin · Posted

      I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff".

      The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
