Catless with a Super10 will be definitely be loud.

Listen to some of the videos on YouTube of these trucks with Catless headers. Mine was borderline too loud, and very raspy, so I put the stock resonator back on. I can't stand raspy.

I don't know your budget, but the best result would be going with Long Tubes, then a Y Pipe (catted or not, your call), then a custom tune.

I think I have all the dyno numbers and gains in my build thread.

Sorry to double quote but how loud was it inside the cab without the CATs and the resonator? Was their too much drone? And when you tuned did you use a dyno or diablo ?

It was only too loud on heavy acceleration. In the cab it wasn't bad really with window up, but windows down I thought it sounded like turds.

 

The resonator really killed the rasp.

 

Drone was never bad, as I've had 4cyl mode tuned out for ever.

 

My truck is street and dyno tuned with HP Tuners by a local performance tuner who is awesome. This is my 4th vehicle I've had him tune. CJ tunes.

Only the front cats are monitored, the 3rd cat (California required) is not monitored and can be cut out without tripping any codes.

Hey thanks TJ you've done this?

So you cut that cats out but still had the resonator? Why did you go with Texas headers and not looks?

 

Was the tune to remove all the codes expensive?

 

Can you tell me what exactly you've tuned on your truck for performance. Hey btw this info is really helping me out a lot man!!!

No I didn't remove mine, I removed the stock muffler and stock exhaust valve and resonator and replaced the muffler with the Magnaflow 12909 muffler and a piece of straight pipe for the resonator. I have the V4 turned off on my truck though so I don't have to worry about the droning.

So you cut that cats out but still had the resonator?

- First exhaust thing I got on my truck was a catback exhaust. I did this at like 2000 miles. That catback had no resonator. So when I installed the Headers and Catless Y pipe later on, the truck had no cats and no resonator......until I put the resonator back in.

 

Why did you go with Texas headers and not looks?

- Simple, price. I paid around $700 for Texas Speed, Kooks are around $12-1300 minimum.

 

Can you tell me what exactly you've tuned on your truck for performance?

- I had my trunk tuned well before headers. The tune at first was to disable AFM 4cyl mode, and improve the drivability and take care of the sloppy shifting from factory. Then, I converted my truck to e85 (wasn't flex fuel from factory like some), so I had the tune updated. Then I added headers and had the tune updated again. The updates to the tune for the headers was not only to cut out the rear o2 sensors from throwing a CEL, it is also to update all the tables/trims to take advantage headers better flow. In my opinion, if you get headers, you should tune.

 

Was the tune to remove all the codes expensive?

- All depends on your tuner. I paid around $450 for my tune, and that included Dyno time. However, like I said before, I have used this tuner for about 10 years now and he gives me a little price break. Heck, he has even fed me breakfast with his co-workers at his shop.

so without the resonator, the headers and catlesss pipe sounded like turd?

 

 

So you would go with a dyno and not hand held tuner?

 

 

I will be looking into the Texas headers

To me, yes...it was too raspy. Some might like that sound, but most find it pretty annoying.

 

Hand held tuners are good for basic bolt ons. However, I'd get a dyno or street tune if going with Headers.

I am also using TSP headers with stock resonator. I have a dyno max muffler with plain exhaust shop piping everywhere else. I have a close friend who has a shop and did my exhaust at cost...

 

As stated, without cats, most will want a resonator. It will make it slightly less loud, but mostly will help control some of the tones (drone) experienced without a resonator in place.

      2015 Silverado 3500 right rear turn indicator failure

      By davester · Posted

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf

      Take an automotive stethoscope to the vacuum pump. Iirc those tick as well.
