    Does anybody know about how much it is to install them at a muffler shop? Just wondering because i saw a post( which is below) while researching. Just wondering if it is worth doing all that work or just taking them in and having the shop do it(If its not a big difference in price). Thanks..Mike

    Look up this member on TN: Bill_c_27
    http://www.toyotanation.com/forum/sh...shorty+headers

    He did this write up on the DT shorty install, if you are able to do this, your install will run just about $50ish for welding, you do the removing and install[​IMG]

    DT shortie headers
    I live in Texas and I like to stay emission legal. I also like to keep the O2 sensors so my fuel economy won't suffer. Here is my DT shortie headers.

    1. I created a form that supported the old manifold using plywood. Make sure the manifold is bolted down securely. You want to make sure the bolt holes in the new header lined up well.

    2. I then cut the manifold at the weld line before the converter using an electric cut-off tool or hacksaw.

    3. I then removed the old manifold from the plywood and bolted on the shortie headers to the plywood.

    4. I then had the local muffler shop weld the header for me. [​IMG][​IMG]

    On a side note, comparing these pics to my JBA's sitting in the garage, I have to say Doug Thorley's look of higher quality. By far[​IMG]

    Not sure.. But Im ganna probably get the shorties later on, and I would just have a shop do the welding for me. Or a buddy who know how to weld...
    The Install and Tear Down isnt too difficult to do....

    I'm sure plenty of people have, they just may not know what a muffler shop charges, which I believe is what youre asking.

    I know this forum is old, but to have your own Short headers installed is from $500 to $600 in SAN JOSE... Time to cut my own headers and follow your guidance. It be nice to find a cheap welder.

    I never came back to update,but I ended up paying $250.00 even. It took about a good 2 hours. But here is something to consider. I have a p0430 code because of them welding my cat with my o2 sensors in place. Remind them not to weld with the o2 because it made the thread as 1 piece.Hope this helped

    I don't understand what you are saying about welding with the O2 in place or what you got for $250, but I weld all day long on my truck in my avatar and I get no codes.

    Also if I lived in your area I would have gladly welded and installed your headers for a benji.

    what i meant was,the headers shouldnt be welded to the cat if the o2 sensor is installed.The heat will damage the threading of the o2 sensor and also just damage the o2 sensor from excessive heat. The $250 i paid was for them to cut the cat,weld it to header,then install it.
