Hey guys n gals...new to the site. This is my second GM truck but doing a VASTLY different build on her. My first truck is an 05 Colorado Xtreme drift truck, while this one is a 2018 Sierra 1500 Z71 Prerunner build that's my daily (it's the 5.3, not the 6.2)

 

My question is...which exhaust is better for pure, clean loud while maintaining a low, angry tone when I get on it? I know Magnaflow is a straight through so no "restriction" while Flowmaster is baffled for tuned tone. I loathe exhaust "pop n bang" like glasspacks and whatnot...so im trying to avoid sounding like every cheap, clapped out beater truck in my area. I am specifically looking for as low and angry as I can get, but clean and clear. I notice a LOT of trucks here go for the "NASCAR" sounding kits and that's a bit too high pitch for me. 

 

I can cut and dump, so I can play with how "loud" it is, but which is best for deep, low, growly sound at all times?

I'm a Magnaflow type sound person. I do not like the chambered style mufflers of most Flowmasters.

 

Most systems are going to stay pretty tame at low rpm because you will still have the 3 cat converters before the muffler acting as resonators. Removing those will give you terrible rasp and that's not what you want either.

Magnaflow has a nasty drone issue. Corsa is an awesome exhaust but expensive. I went with the Borla ATAK system. No drone and loud when you get on it.

There many different mufflers made through magnaflow, not all will have bad sounds.

 

Never had any drone problems with the magnaflow I used 5 years ago. They don't sell it anymore but it was a oval body about 22-24in long.

I just switched to a Carven Type R muffler. I was a Flowmaster man all day until I heard the Carven mufflers. You can buy just the muffler or buy a full cat back from them. I love the sound.

MBRP. Very deep, rich, throaty sound. Cold start is super loud. Sounds good at idle and very loud from 2000-6000 RPM
MBRP uses low grade stainless steel. They rust out easily. If you live somewhere where they use a lot of salt on the roads I'd stay away from MBRP.

I have a 2017 GMC and am running a FlowFX by Flowmaster with a single in/dual out and it leads to large echo tips.  It's VERY deep, NOT crackly at all... and SMOOOOOOOOTH.

 

I like it.  

 

I once had a FM 50 series on a 350 Vortec, and they sound similar, with the FX sounding a bit deeper.

      2027 GMC Sierra: Official Discussion

      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.👍
