Finally had the tips moved to rear quarter flush and with a slight stagger.   Sent from my HTC One using Tapatalk

The number of hours spent on any given forum are directly proportional to the number of dollars spent on subject vehicle.   Ask me how I know.

I'm looking for a 2.75 muffler for my 5.3... Does anyone know who makes these? I looked on flow master and magnaflows website but they don't have any. I would rather weld one in instead of buying a whole system. And also, is there any specific offset or just straight in and straight out?

A muffler shop will be able to fit the muffler for you, a 3 inch won't be hard at all for them to fit. I accidentally bought a 3.5 inch and they made it fit. Mine is a straight in-straight out muffler.

Did you have them do any deletes? like the resonator or anything? Im assuming you would want to change mufflers but also delete the huge resonator/cat that is closest to the tail pipe end.

My bank account, and likely the bank account of some others, don't like you anymore

Tune is inevitable for me as well as corsa exhaust. The toss up comes with headers or CAI? Hell their within 200$ of each other.

 

I will likely go CAI. Headers would be awesome but too loud for daily driving. So to have that effect get a valve to switch from the exhaust to dumps. Idk how much that cost. But best of both worlds if you want to drive quietly and off road with it screaming.

With the right catback set up, headers can be extremely quiet. The headers + corsa on my crew cab is nearly as quiet as stock when daily driving. It was actually too quiet for me so I put an exhaust cutout in to wake it up abit.

$2,300 for catted y pipe and headers, then you have to have it tuned..... but man does it sound good

 

If you just want the noise, you can easily run headers without a tune. It will flip a CEL on a regular basis for cat efficiency, but some sort of scan tool can easily clear that.

Question...I want the performance advantage headers can provide but want the quietest setup for daily driving and towing on the weekends. Do you have the Corsa Touring? Any chance you have some sound clips?

 

Thinking outloud here since I really don't have any first hand experience with this...Could a guy just run Long tubes and catted Y pipe with the remaining exhaust stock? Am I killing any performance gain?

 

Like I said I want it pretty mellow until about 2500 RPMs since that is where it sits when I tow my trailer but after that loud is good.

I have the Corsa touring on my crew cab, but from the looks of it, they no longer offer it for the new trucks. I'll see if I can get a video this weekend. All of my current ones are with the cutout open so it's got a significant bark to it.

 

With my 2009, I did run the long tubes with the factory exhaust for awhile and I wasn't happy.. The factory muffler isn't designed for headers so it droned like crazy. The headers and the corsa touring was actually quieter in comparison.

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
