2009 5.3 Exhaust

[Hieneken49]

What are you guys using for mufflers on your 5.3's. Im a dodge guy thats giving GM a try and im not sure how the whole vortec backpressure legend works. I ran a magnapack muffler on all my dodges and loved it, but it was a straight through design, not sure if its gonne kill my engine on my 09 sierra.

 

Let me know what u have!

Edit: I tried searching, either i dont know how to use this earch or it just sucks. I get no results for everything i put inot the search.

Corsa, or Magnaflow would be my pick. Use the search button. There are lots of topics on this already!

 

I had a Magnaflow dual exhaust system on my 6.0L Silverado, and I loved it!

Youtube is you friend, but honestly if you want a nice deep not too loud sound, then go with magnaflow or Corsa, Corsa will have NO drone, and magnaflow you may get some, but most don't notice it. Also you could go with a flowmaster of some type, I have heard the Super 44, 50 Series, and the 70 Series, and they all sound good too, it's pretty much personal preferance on the sound.

There are also many others, but those are some of the more popular ones

Flowmasters sound really good on GM V-8's, however you'll notice a really fowl droning sound when you go into V4 mode. Only downside to the AFM of the 5.3 V8. This will happen with any aftermarket exhaust.

Welcome from the dark side. 09 GM 5.3s have a third catalytic converter so a catback on them is not as loud as 07-08s. If you plan on putting on headers later I would wait to put a catback on because the header Y-pipe will not mate up with an 09 catback. You have to get 07-08 headers and 07-08 catback for them to bolt together on an 09-10.

I have a Flowmaster 40 series and I love it! It's been on for about 2 1/2 years now and no problems. It does drone a little in 4 cylinder mode, but all of them will do that.

Corsa doesn't have any drone. Corsa is as quiet or quieter in the cab with AFM then the stock exhaust.

 

BUT, you are going to pay a premium for a Corsa system. I bought mine from Justin at Black Bear performance. I am not sure if he has anything available for the 09+ or not. The exhuast flange is different on 07-08 vs 09+.

 

I know a lot of guys have bought Corsa off of Ebay for a good deal.

Performance Peddler.com has some of the best prices I've seen.

 

Not a fan of flowmaster. On my 03, I lost low end torque, mpg and rusted out in under 2-1/2 years. It sounded good, but not what I expected. My vote is for Magnaflow, Corsa or Borla

I went with a Corsa replacement muffler. Sounds great, and no drone.

I believe JcWhitney sells Corsa db-series separate.
