I'm looking to long tube headers and Y pipe for my 2014 Silverado 5.3.

What brand do you think have the better price/quality ?

I'm very interested in the Speed Engineering kit:

What do you think about ?

Any experiences ?

And most important: the headers fits good or I have to be mad like usual to install them ?

Thanks in advance

I installed mine 2 weeks ago. Have the headers and y pipe v-banded to ensure no leaks. That is my only complaint is the slip fittings leak and have a little play. Other than that install was a breeze. My setup is 1 7/8 headers, y pipe, 3.5" exhaust into a Borla XR1

It is very interesting, also for the bypass valve and the good price, do you have the TVS1900 or the TVS2300 ?
My truck have the Flex fuel sensor, do you know if it works good with it ?

Kooks, American Racing Headers and Stainless Works are the best for these trucks. There are cheaper options like the ones you showed, OBX, and PaceSetter but they don't always use the best 304 tubing, it will often be much thinner than the first three I listed, fitment will be poor at best, while KOOKS, ARH or SW will fit perfect and last a lifetime. 

 

But you are comparing $500 headers and Y-pipe to a $1,500 set, so there is a big jump there. If you are going cat-less, you will also need to have a remote tuner or dyno tune done after the install to turn off the Check Engine Light (CEL) You were talking about a turbo before, decided that maybe a supercharger might fit your build a bit better?

Nothing wrong with Speed Engineering headers at all.  If you can afford to step up one notch, I would go with Texas Speed, the build quality is slightly better, and they use seamless primary tubes, so they may last a little longer.

It's gonna be loud as hell lol.

 

Prepare for loads of terrible sounding rasp and drone. Or just wear ear plugs.

Yes, I'm still thinking about but reading the comments and knowing about the bypass valve, I think that maybe the supercharger is a bit better for a daily drive also considering the easy installation compared with a turbo, especially for our mechanics that don't know LS engines very good.

Do you can suggest me a good tuner ?

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
