Not Happy With Your Exhaust?

Well, it seems that I may be back where I started again when I was looking to ditch my Magnaflow setup a few months ago. Yeah, I'm picky. :D I've had the Corsa Sport exhaust for a few months and it's been great. I did notice a bit of drone on the highway above 70, but wasn't a big deal. Until yesterday, when I just drove 300 miles with 4 ppl and luggage in the back. That "minor" drone above 70mph really starts to get to you after awhile. Enough to the point where I'm considering going back to stock, again. Well, unless I can find a good deal on a Touring muffler, but the price is way up there. I got my Sport System for about $600 on eBay, but Touring systems are a lot more.

 

I should also note that in my particular case this is regarding exhaust on the 6.0l V8, which tend to sound way louder than the 5.3l V8. Almost night/day difference between the 2.

 

So I noticed on the poll there are quite a few people who aren't happy with their setup. But the vast majority of posts are people just thrilled with their various setups. Well, it's time for the negatives. So why aren't you happy? What system do you have? Is it also because of the drone?

 

And, are you planning or have you already gone back to stock? Any and all feedback is welcome. :thumbs:

Well if you dont like drone, definetly stay away from flowmaster lol. stock is the quietest interior sound you will get, but then it wont sound good outside. Thats usually where Magnaflow shines thought. If I remember you had the 22" long Magnaflow, that quiet thing still droned? lol

Put a small straight throw muffler (Magnaflow) or resonator in front of the Corsa sport. It will quite it down a bunch and you loose no performance. Cheaper than a different system.

Yeah, I forgot which Magnaflow I had previously, but it was the longest quietest one they could find. The drone was pretty bad. :( It only gets worse as you get more weight in the truck. We did add another resonator to that setup, which helped, but not quite enough. I also didn't care for the sound/tone of the exhaust after that.

 

But the resonator is a good idea; my Dad actually just suggested the same thing. He had to sit in the back on the trip here and wasn't thrilled with the drone either. :) Just gotta see what will fit and hope it will get the job done. I just really like the way the Corsa Sport sounds, so I'd much rather keep it.

Have you thought about putting some sort of sound deadener or reflector between the muffler and the truck? If you like the sound of the exhaust, overall, maybe the answer isn't to change the exhaust, but change the way the sound gets into the truck. If you can reflect some of the sound away OR have something else absorb some of the sound, maybe that'll get rid of your drone.. or, at the very least, reduce it enough to not be annoying?

They make Magnaflows in 12 to 16 inches long by 4 to 6 round. The corsa will take out the Magnaflow drone and the overall exhaust will be quiter. Have seen it done. But a good resonater 3 in 3 out straight through will probably work as well. What ever you decide on, get stainless. And 3 in 3 out is Id so your Corsa pipe will slip in to it. You can get 3" stainless clamps so you can try multiple mufflers till you get the right one, then weld or clamp it in.

 

Merry Christmas,

It doesn't look like there is enough room to add a resonator in front of or behind the Corsa muffler. At least nothing big enough that would make a significant difference. That 3" exhaust takes up quite a bit of room. :) We're looking at a few other options, such as running a slightly smaller pipe and a resonator around the muffler. Just something to help catch and reduce the sound.

 

So, still looking into other options and hoping to avoid going back to stock. I suppose I really wouldn't mind, I've just gotten used to the loud aggressive corsa exhaust. :lol:

 

But I have plenty of options, I'm mainly just curious as to what everybody else has done who wasn't happy with their exhaust systems.

There is enough room in the ext cab trucks. There is a picture of a magnaflow on a truck in performancetrucks.net. I used to have it saved to favorites but deleted it two weeks ago. Might be able to find it again. There may not be enough room in your Danili if the muffler sets too far forward. You may have to get a touring muffler. Corsa will exchance with you for a tidy sum. Or you may find one on ebay. I saw one on there last year. I have a spare one but don't want to get rid of it.

 

May the force be with you,

Yeah, I've seen 'em before, but they had the 5.3l. On this truck (6.0l), everything is 3", which is quite large, and takes up way more room. But it's going back tomorrow so they can try the "unique" resonator setup. Also going to compare the volume before/after with a Decibel meter to see if it helps enough.

 

Oh, and I did actually call Corsa awhile ago about swapping out for the Touring muffler only, and they wanted something like $550. :lol: And since I paid about $650 for my entire system, you can see why I'm looking at other options! I had also been checking on eBay for awhile, but they seem to be quite rare these days... at least for my truck. :)

Not sure what you mean by 5.3 being smaller than 6.0. My 5.3 has 3" pipes from cats to tips. Not seen a single pipe Corsa on a truck less than 3: Now the GMPP system made by Borla is 2.75 same as stock for the 5.3. Got one almost new in the garage.

 

Yea Corsa thinks that muffler is made out of gold.

 

Hope you find a solution. I tell every body to go with the touring but you have that gotta be LOUD crowd shouting me down.

 

Have a good one,

 

Don

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
