Seeking Advice on Exhaust Systems

I recently purchased a 2015 GMC Sierra 1500 and am considering upgrading the exhaust system. I’m wondering what options are out there, specifically for aftermarket or replacement exhaust systems.

What I’m Looking For:

  • Performance: I want something that enhances performance without creating too much cabin noise.
  • Sound: I’ve seen videos of various setups online, and I’m curious about the differences in sound. I’d love to hear from anyone who has experience with specific brands or systems.
  • Installation: Is this something I can do myself, or should I take it to a shop?

Brands to Consider:

I’ve come across a few popular brands like Borla, MagnaFlow, and Flowmaster. Any recommendations? Which brands provide the best balance of power and sound?

Pros and Cons:

If anyone has experience with certain systems, please share the pros and cons. I’m particularly interested in:

  • Durability: How well do these systems hold up over time?
  • Emissions Compliance: Are there options that are compliant with emissions regulations?

I appreciate any advice or direction you all can provide. Thanks in advance for your help!

If you’re looking for an exhaust upgrade for your 2015 GMC Sierra 1500, I highly recommend Flowmaster or Borla systems. They provide a great sound without being too loud. Installation is pretty straightforward if you have some basic tools like a socket set.

I’ve had a Borla system on my truck for about a year now, and love it! Just make sure you have a friend to help with the installation; it’s a bit tricky alone.

I installed a MagnaFlow system on my Sierra. It’s quieter than I expected, but has a deep rumble that sounds great! All I needed was a jack, a wrench set, and some patience.

That’s interesting! I heard MagnaFlow has great build quality. Was the installation difficult, or would a beginner manage it?

It was pretty manageable, honestly! If you can follow basic instructions, you should be fine. Just take it slow and double-check each step. YouTube videos can be a lifesaver too!

If you’re into sound and performance, don’t overlook the Gibson exhaust systems. Some friends have them and they sound aggressive yet refined. Just remember to have a good impact wrench for installation!

8

Gibson’s on my list as well! Does anyone know if they come with everything needed for install?

9

Yes, most Gibson kits include all necessary hardware and instructions. Just remember that you might need some extra hangers if you’re swapping out the stock system completely.

10

Just a heads up! Some systems might require additional tuning afterwards. It’s usually minor but worth checking out. You don’t want any check engine lights after the swap!

11

Good point! Have you experienced this with any specific brands? I want to avoid those issues.

12

I’ve heard that some of the cheaper brands can cause tuning issues, especially if they use smaller pipes. Stick to well-reviewed brands like Borla or MagnaFlow to minimize problems!

13

Honestly, I just want my truck to sound mean while still being legal. How loud is too loud for daily driving?

I’d say it depends on personal preference. You could go for mid-range noise like a Borla which sounds awesome but isn’t overpowering. Just remember to check local noise regulations!

15

Exactly! Sometimes I think quieter exhausts can be just as enjoyable, without annoying the neighbors. Any tips on keeping that balance?

16

Experimenting with resonators can help manage the sound. They can really fine-tune the pitch and volume of your exhaust.

With all this talk about exhaust systems, I wonder if I should start a band! ‘Sierra & The Rumbles.’ Anyone want to join? :joy:

For a solid performance boost, I recommend the Borla Cat-Back Exhaust. It offers an aggressive sound while improving horsepower and torque. Plus, it’s known for decent fuel efficiency gains.

19

I’ve heard the Flowmaster Super 44 is a great choice too for that classic muscle sound. Anyone have experience with it?

I installed a MagnaFlow system on mine, and the sound is incredible—deep and throaty. Performance gains were noticeable, but it didn’t significantly improve fuel efficiency. Worth it for the sound alone!
