I love the people who get straight to the point and not spend 20mins talking about random things thank u guys great video👍
I own a built 2012 srt8, they are so much fun but the amount of chrome they come with factory is scary but this thing has even more chrome!
Looks like a good job installed, really like the little more detail in the vids guys keep up good work
Awesome content
Thank you!
Stock these make about 380-385awhp so putting down 433awhp is a good jump. I know these trucks don’t wake up much with just bolt ons without the tune so props on adding a good tune. I own one myself
Excellent!! How did the two systems connect? Is the sw 3” to borla 2.75”? Is there a factory pipe left in there?
Should of did before and after dyno to see if added more horsepower like people claim
Can you guys send a tune with the same mods added you guys did?
Does anyone know if Scatpack headers off a 2020 Challenger 392 will fit on a Jeep Srt 2014 392?
Does that void extended warranty?
Should have tuned that srv to activate around 4500-4600rpm so you don’t have that huge dip in power
What is the diameter of pipe where the two systems connect?
This was a 3in collector from the header to the back.
What was the numbers before and after install? I thought off the showroom HP was 475?
An engine dyno differs from a chassis dyno which changes the HP. We did not get a base tune on this, but after the tune we were at 433 HP.
@@BlackdogSpeedShop I would have been interested to see a base line to see if what was done is worth it. Sounds better than stock but how much was gained from the upgrade and tune.
@@thomasbadgero6886 Numerous other GCSRT's have put down ~380hp / ~400tq to the wheels on a dynojet. Safe to assume it was there for this as well. Some decent gains with those headers and the exhaust. Would like to see it sans cats, of course, or even electric cutouts.
@@thomasbadgero6886 it puts down about 390 due to AWD the scat packs put down about 425 wheel stock its RWD only so less DT loss
What kind of rims are those
They’re stock Jeep srt rims , they came with the 2013-2015 models
