The Flowmaster 70 3" single-in/2.5" dual out on my '03 4.8 RCSB was fine when I first got it, but since I added the Radix s/c, it is too restrictive; robs power and doesn't even sound good anymore. I am considering going to Corsa for a replacement. Has anyone tried them? How are they as far as sound and flow? My first preference was Dynomax, but they don't make a muffler with an offset entrance 3" pipe. Also, Corsa CLAIMS to eliminate in-cab resonance via some proprietary design. Is this effective? Any information and experiences would be welcome. Thanks!! :mad:

 

Peace and Coolness,

Sounds almost political: 'CORSA' -- 'CORSA'. Be sure to let folks know just WHICH Corsa. There is the touring and sports verison. There is the single exhaust, there is the dual exhaust.

 

One version is very raspy sounding (I called it East Texas Bubba truck sound), the other is more refined sounding. None have resonance, but one version can be so raspy that even there was resonance, it wouldn't be heard over the rasp.

 

Just my opinion, y'all!

Magnaflow has 3" offsets, and they're reversible, so no worries :mad:

 

Scroll down and look

I gotta go with Dolan here, Magnaflows rock! I like the corsa mufflers too, I drove a dealer demo Ext. cab Z71 with the 5.3L and a corsa side exit setup. Sounded good, but it cost too much to suit me.

 

Good luck!

it would seam their propietary design must be in the muffler itself, so can you get just a corsa muffler? i can weld up my own aluminized system for $50, but haven't been happy with my past choices in muffler because of the interior drone.

You cant get a Corsa muffler seperate. It sucks but thats the way it is. Otherwise everybody would buy the muffler and not the million dollar cat-back.

D**n !! I didn't know that. :mad: Well, so much for that idea! Guess I might give Magnaflows a try, as several people seem to like them. One other question though. I really like the Dynomax Ultraflows, but they don't seem to make one with an offset inlet pipe. Would it be advisaible to try and put in my own offset? Or will the bend be too restrictive?

Yeah, it sucks. I searched high and low for a Corsa muffler. Lot of f-body guys dump the Corsa muffs for something else. Right after I bought my Borla XR1 there was a dam Corsa muffler on LS1Tech 2 days later! It wasnt meant to be! :flag: Im happy with my XR1. You can set your exhaust up pretty much however you like it. It will just be built around your muffler. The bends really wont do much for to your performance if anything. When you start pushing high HP numbers is when I would start worrying about exhaust bends. But in your case you should be fine.

The Corsa systems give you the best of both worlds - quiet during normal driving with no interior resonance and aggressive when you lay into it. It's like having 2 different systems! Their Sport system has a more aggressive sound than their Touring. Sales are usually split between them.

I had a CORSA Sport and it droned in my Suburban. REAL BAD. Through 2 layers of Xtreme Dynamat plus spray on Dynamat stuff underneath.

 

They swapped it out for a CORSA Touring and it is AWESOME! Actually need to turn down the radio to hear it.

 

 

Unfortunately, now I can hear the wife complaining from the back.........

      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

      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.
