are these headers legal in california?


  • The JBA Cat4ward Shorty Headers (05-10 GT) are not approved by the California Air Resources Board. We do have a pair of headers that are C.A.R.B compliant, and I will attach those links below for you!

    Install Tips

    It took me a weekend to complete this install most likely because I took my time and did it in sections. Removal of H-pipe, O2 sensors, steering rod and manifolds. then installing the headers and finishing up. Might have been a day if i focused on it. As for the instructions, I have and some additional tips. TIP ONE: Something that was helpful to me was not to be shy with the penetrating solution. especially with the manifold studs. I had read a lot about that being a problem, I just used a 5mm socket and removed them after about a half hour soaking in the liquid wrench. TIP TWO: When installing the headers weather you are using a new gasket or not; install ALL 4 top header bolts and lock washers on the heads, screwing them in about 5 turns then while under the car raise the header and install under those bolts the carefully install one of the center bottom bolts, then install the remaining bottom bolts. This will alleviate the headache of getting the bolts in one by one. TIP THREE: Get yourself a 3/8 in. "ratcheting combination wrench" to tighten the header bolts (this will save you hours). Most of the bolts cannot be reached with a ratchet. TIP FOUR: On the passenger side remove the motor mount bracket BEFORE you attempt to get the header in there. due to the starter part of the bell housing it is more difficult to get the header into position. Learned this the hard way. Once I got it together the car felt and sounded great, I already have Pype Bombs on this car and these headers made that deep raspy sound turn into a smooth deep purr. Still pretty loud with the bombs and well worth it. Good luck

    tight fit

    paid gtr to install, was a hand full for them. had to drill out the wholes on the headers to get screws in. plus needs small indentation on the passenger side headers near the 2 bolt to tighten the nut, they welded some bolts to the header flanges like the stock ones. easy bolt on to xpipe. car seems a little lower in sound but when you open it up or downshift, it sounds great. it gets up and goes even rumbles in downshifting i recommend pay someone unless you have a couple of friends handy

    Performance ok, installation NIGHTMARE

    Ordered the set and some 1/8" thermal wrap. When I got them they were shipped fast and looked cool, the finish on the mating side looked a little crude but whatever. So, wrapping shorty headers is a horrible and tedious mistake, at least with 1/8" thickness.... Onto installation, I had a lift and easily unbolted the exhaust system and unplugged the O2 sensors easy all except the one at the top of the passenger side. I had to unscrew it from the pipe. Once I unbolted the starter and the steering rack (loosen rack bolts from the top, the nuts are welded in place) I started tackling the exhaust manifolds. The biggest pains are just ahead so keep reading. Once you remove the bolts from the manifold and take off the manifolds you have to remove the studs... double nutting the studs and backing them out was very tedious and actually getting the new bolts in place was hours and hours of failure and exhaustion... !!!IMPORANT!!! It would benefit your blood pressure to re-tap all the stud holes since mine were all sorts of warped out of shape. When the time came to put the heavy headers in, the bolts only wanted to cross-thread EVERY TIME I placed it. ALSO, the instructions SUCK... if you see the open cuts in the flange at the top rear of the header that's because you are supposed to put the bolts into the head before placing sliding the headers up into them. The instructions attempt to say this but the English is very poor, be sure to get all bolts started before tightening them down or you will cross-thread them. ALSO, you cannot remove the steering shaft, you have to push the steering rack foreward to get the steering shaft out of your way. ALSO, if you do wrap the headers you will need to remove the battery and battery box from the car or you will loose all hope for getting the rear most bolt tightened. I also changed out the stock exhaust for pypes, sounds nice but I haven't seen any performance gains, Only fuel mileage... I need to get the car tuned, It's probably running lean and melting my cats.

    Freakin Rad

    I cut my mufflers off and it sounded a little raunchy, but the headers cleaned up the sound A LOT. Revs a little smoother. you can feel the power really kick in @ 4000rpm. And it runs strong all the way to 6k, unlike stock which tapers at 5500 or so. Tires break loose easier too. Worth the money if you do the work yourself. Think twice if you go to a shop, minimum 4hrs labor.

    Nice bang for buck

    Install was pretty simple with an engine lift. Doesn\'t come with header gaskets (it tells you to reuse the stock ones... not smart). Got some from local auto parts store for abour $20. Gains = revs up faster, more torque and added a throatier sound. Nice for the money but if you want more power and noise, go with longtubes.

    easy power gain

    install was pretty simple, just took awhile with the help of a friend. Put it on jack stands and used an engine lift to raise it up a bit. Just took off the motor mounts and the starter underneath and fit right in. If you are looking for \"loud\" headers, do not go with these... Though, you can tell it\'s a more throaty sound; i have slp x-pipe and flowtech mufflers. But, If you\'re looking for a good power upgrade you can feel throughout all gears... I have to recommmend JBA shorties. - does not come with header gaskets, and i will not reuse the OEM ones like JBA recommends.. got new ones from O\'reilly\'s for about $20.00

    Great Mod

    This set of headers is a great buy. I could both feel and hear the difference as soon as they were added. I would also highly recommend one of their programmers with a custom tune to go along with them(much more of a gain in hp).

    Shorty headers - Excellent Mod

    Next to the CAI and tune these are my best mod to date. Unlike some mods this is one you can actually feel. Definitely recommend it.

    Shorty headers

    I must say that these headers make a world of difference alone. And with the JBA catback exhaust the sound and response is better than expected, especially after adding other intake and programmers.
