I did all the work myself. The mid pipes where a biatch but the car was on jack stands. A lift is a must. The catback is very easy to install. And I believe the tips are 3 inch. The awesome part is the pipes use the factory hangers. You will love the setup. I also did the headers, but that is another story!

please let me hear that story. i really want to get the headers too, also on sale as a complete kit. i have heard that unbolting the motor is a must, is it true?

I've installed all three JBA components by myself, on my back on my driveway(actually my buddy helped with the catback)
The catback is a snap, the Mids are easy too. One heatshield to remove, 4 bolts, and two clamps.
Yes, the headers are a total beeatch to install. The headers arent hard in a technical sence, but very hard to get at and torque down the various header bolts.
I think I did a write up on the mids..I'll search

For the headers I used my dad's lift. He is an auto mechanic, but I did the work myself. I can't imagine trying to do the headers with the car on jack's. First thing I would say about installing the headers is make sure you give yourself plenty of time. At least 5 hours. If the engine is hot, you'll need at least an hour before you can touch anything!! I took my time and went very slow, took me about 8 hours. Some guys have claimed they removed the old and installed the new stuff without removing the motor mounts and lifting the engine, I don't know how this is possible. It is so tight under there. I took my time and lifted one side at a time. My dad also suggest that I use anti-seize on all the bolts. I think that's what it was...been awhile since I did it. The passenger side is the most difficult because of the starter. DISCONNECT THE BATTERY!! Also, make sure you have all the right tools. Swivel sockets are a must. Oh, when you crank it up the first time it will smoke like you set a bomb off. Don't be alarmed. But all of the work is totally worth it when you mash the accelerator the first time. Good luck.

Not a problem at all.

Its a challange, and the reward knowing you did it yourself is awsome

i got my headers/catback in teh mail, ran up to my speedshop and dropped my car off last week.

getting it back tomarrow(they worked me in and its been agonizingly slow)

they call me friday tho goin "dude didnt you have highflow cats?" so i call 402 motoring like wtf? apparantly JBA was back ordred on em, so im still waiting.

gonna be running stock catted mids with jba headers/catback for another week and a half or so.

thinking of doing the middie install myself. ive got a decent set of tools and pretty mechanically savvy. but im still nervous when it comes to operating on my baby.

CAI and 180-stat were a breeze for me. think i ought to try the mids? how long of a job would it be considering the rest will be done? i just dont wanna screw up the amazing work my boys do at the speed shop

it should fairly simple, just prepare to spend a good amount of time getting things lined up right.......unless they weld everything then you're SOL.

To answer your original question, the 5.7L cat-backs are a 2.5" pipe diameter pipe. The mid-pipes are 3" into the converter and 2.5" out of the converter back.

And mid-pipes aren't backordered at HHP. Just order online or give us a call and we can ship out any JBA Charger product same day. All of our headers, mid-pipes and cat-backs are on sale through SEMA at some awesome prices.

Joshua, HHP
