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!

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 :lurk:

      Diesel or gas?  The 37s will obviously, drastically reduce mpg, but the gasser will take a bigger hit to mpg, and power.    I wouldn't sweat a gear change on a duramax at all, and unlikely on the gasser either. You're obviously not concerned with acceleration or towing, and the 10spd will find itself in the right gear without much hunting, if any.

      OCI, not when but why?

      By Grumpy Bear · Posted

      I understand. It is disturbing to think a manufacture asks so much and gives so little in engineering support. This is not a GM issues, this is a greed issue and one the ALL practice.    My intent was not to remove the wind from anyone's sail but rather to point out the areas deficient so that they can be discussed with improvements the goal. But to do that you have to know the truth and what that truth is.    The commercial interest are honed in on a few select issues in which they control all the variables and are not forthcoming in the least with their customers about the details. Failure is the only thing that drives these people to improvement. One way not to fail it to manage public "expectations". The set a bar they can clear and put their thumbs under the suspenders with chest puffed.... Only the internal data tells the story fully. As we don't have access to that for decades then we have to generate it ourselves. UOA's with data that matters.

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.
