So I'm about to buy a set of jba headers and I'm wondering if they are just a bolt on? Is there any welding cut anything else I have to do? Will they fit right up to the collectors of the factory collectors just above the cats? And I would also like yalls input on how long did it take to install them? I'm gonna to be doing this at school for a test and I wanna make sure It can be done.
I have JBA Shorties on mine and they're just bolt on, no welding/cutting/anything required other than removing the old and installing the new. Mine were installed over the course of two days with a bunch of other mods.. There's a thread on here someplace where one of our lady members did the install, I don't recall who it was though. I will say this, it's gonna be a tight space to work in. We put mine on with the heads off, so it was easy lol
Who Farted? BEANIE!!!

Ok good cause my teacher doesn't wan this to take all week. I thought for some reason it's wasn't just a bolt up but thanks for the info.
Make sure you use new factory gaskets with them and not sure if the 6.1 hemisphere bolts or the same as the v6 but that's what most guys use...the install should only take a day..the only thing I removed was the lower motor mount nuts and studs so I could slide the motor side to side....
It should take you about 5-6 hours for the install. I did it at my dads shop on a lift and I'll tell ya it's tight. The headers are gonna have to go in from underneath so you might want someone on top to help you bolt them up

So when you go to install them from underneath can u fit them up against the heads with the exhaust still there? Like the cats and all the piping from the collectors back? Or do I need to remove them to get the headers up to the heads?
Not sure. We took the whole system down to get it out the way. Trust me, your gonna want the room.
Get the mid pipes out of the way (2 clamps since you HAVE to disconect them from the manifolds anyway).
DO NOT attempt to use the crap felt gaskets that come with the JBA headers, make sure to use the Mopar header gaskets.
While you are getting your gaskets get a set of 6.1 header bolts or Stage8 locking header bolts <What I use>, but be prepared to reuse 1 old ones, the one with the dip stick tube attached.
By far the easiest way to do this is to remove the head or the entire motor. Since that may not be an option your gonna F@#$ your knuckles up and you will not be able to get a torque wrench on most of the bolts. Torque is important here as these are Aluminum parts that heat up.
DONT BUY JBA MID PIPES!!! THEY SUCK.
Use long extensions on a torque wrench to torque everything down...on the 5.7 its 18ft lbs I added another pound to compensate for the long extension...you can access the bolts through the wheel well on the underside with a wobbly socket...
Ehhhh this is starting to sound like a nightmare... Busted knuckles... Hate those. I'm having second thoughts now... I don't have an extended amount of time to where I can pull the heads or motor.
Don't be a wuss and man up. If you watch how you put your hands in the small areas your hands won't get that beat up. You'll be fine, just get you some mechanic style gloves.
Took me 4 hrs by myself. I have pit and lift so it's the perfect setup. Used stock bolts and metal stock gaskets. That was 5 years ago no leaks still. No head removal. Just the mods for more room. I used a swivel ratchet and it was a big help.

Alright i think I will have to buy a set sometime next week, whats the difference with sound? is it like other headers where when u are at idle at a red light u hear your exhaust under the hood?
It will definitely add a more throatier tone to your exhaust. Not sure just how much louder it'll be under the hood but it'll sound nicer out the back. My advice, when u get them I'd send them off to jet hot for there 1700 degree coating. It'll help keep the under hood temps down since using the factory heat shields will be very difficult.
I had mine installed yesterday. Thank god I didn't tackle this on my own. A hoist is a must, and as previously mentioned, it's very tight in there. We had to break out the torch a couple of times for seized bolts. My mechanic couldn't believe it was listed as a 4 hour job(way to long to install headers). It's so tight in there to remove the factory parts. It ended up taking 3.5 hours. I was expecting maybe 2hrs. In the end, it seems to have a little more power. I have the reso delete so it doesn't sound any different.
