I dont know how you can beat TSP headers for the money. My GM Borla is perfect for now, but when warranty is up gonna be real hard to not be putting those in the next day with a tune.

Shorties seem like a waste of money to me unless you have a really tight space like on a swap car, or real low clearance on a slammed car.

You're not lying 632$ for headers and a Y-pipe hard to beat.

This is the 5.3 with Flowmaster 10, from inside the truck, rear sliding window open, all other windows closed. Moderate acceleration onto highway.

Yeah i've been reading about short headers all days and it's about equal to just adding a MIT, for a lot more money. Been watching Matt Earle's video with the XR1 40085/Kooks longtube, i love the WOT sound and warm start is okay. Cold start sounds loud as hell. The rest of it i love.

 

 

Thanks for watching. The cold start on anything with headers is pretty loud, but you can actually fix some of that with a tune and keep the RPMs down some at the lower temps. I am actually running the 40943 oval XR-1 now and should have videos soon.

I can say, my cold start is not super loud. The resonator helps a lot.

That truck looks familiar.

Ha i figured it would be someone's on this board.

 

I was thinking you had the right idea with the oval muffler and then adding headers, so it didn't become overly loud like the round XR1s. I'm listening on good speakers now to see what i think i like.

 

Did you notice any MPG gain with the exhaust/headers/MIT/tune?

 

I noticed where you said you probably wouldn't go headers again, was the Dyno reading posted with a tune/headers/MIT/exhaust?

Sorry my video quality sucks.

 

I honestly didn't leave the truck stock long enough to get a decent baseline.

 

I would say I am on par with other leveled trucks running 33" AT 10ply tires.

 

I get 16 mixed mpg, 20 highway with premium.

 

I get 13 mixed mpg, 15 highway with E85.

Here are gains from headers. Both were with done exhaust/MIT/tune, only addition was headers.

Damn those aren't bad number by any means. Your premium numbers are around what i was getting stock. Combined 16 overall and 18ish on the highway give or take. With gas Now it's 13ish in town with pure gas, and this is trying to be conservative :(, I'll find out for sure next weekend what it's doing on the highway as i have to travel 330 miles to Finger, TN round trip. Willing to bet it's pretty bad.

 

I keep watching header videos and can't help but want them at the end of the day, especially if i go a similar route to your setup and it gives me the best of both worlds. I'd love to see a hard acceleration video if you could get one like Matt did.

5RWill, my truck has AR Headers with cats running the OE exhaust. It is quiet when cruising and has a nice growl when starting and accelerating. The headers took it from electric motor quiet to sounding like a sport truck. I tried both a Magnaflow and Corsa exhaust systems with headers and went back to the OE exhaust. I did have the flapper valve removed due to the substantial exhaust restriction it causes, even when open. With headers, the Magnaflow volume was too high for my taste and didn't care for the tone. The Corsa was just plain too damn loud. It was loud with manifolds and OE cats, but with headers the volume was about three times higher. I knew from the first start up that it was not going to work. Yes, those were both expensive lessons. My truck also has an MIT, ported throttle body and BlackBear tune. I really enjoy how it sounds. For me, it is a great combination. I know there is some HP loss with OE exhaust. At WOT (which my truck rarely sees) it has 5 lbs of backpressure which should equate to about 6 ~ 10 HP. Don't like it, but I can deal with it to have the sound both my wife and I like. Correction, she can live with it, I like it.

 

Did I notice any MPG gain? No, don't think so. On a nice road trip with the cruise set at 75 mph, I can get as high as 19.8 mpg. Driving 10 miles to work with some city driving it usually gets 15 ~ 17 mpg. I don't drive like an old lady, but not like a teenager either. Just moderate/aggressive.

I'll see what I can do for an acceleration video. I can do in cab no problem, but that doesn't do it justice. I'll have to find some empty road where I can put my cell down to record and hope that no one steals it :P.

This is well said.

 

I bet you would be happy with my setup. It has the best of both worlds as well, but just not as "tiny" as you get with the stock muffler.

 

If you want to explore or throw $100 more into your setup, cut out that OEM muffler and throw the Borla I have on in there and leave the resonator in place.

I think i'm going to do TSP headers and a similar muffler to Ryan. I'm glad i'm not the only one who thinks Corsa is just overbearingly loud. I do like the tone but i couldn't drive with that thing all day.

So with the TSP headers and a catted Y-pipe i would just need a muffler and tip and could have someone put it all on and go? Or do i need to get a resonator as well? I do want split rear but i could wait for that.

Also are there any downsides to headers? Googling i saw mention of leaks and bolts backing off due to harmonics introduced in the engine bay.

    • 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
    • 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.
    • 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?
