Umm... longtubes won't pass smog??

2) Becuase the word "fabricate" isn't in my vocabulary. I don't know the first thing about creating auto parts from scratch, don't have a single tool for cutting metal ('cept maybe a sawzall with a metal cutting blade) nor do I have a welder. But most importantly, I don't have the experience and knowhow to do those kinds of things...

Finally the sniffer test(almost all in cal. have to go on the dyno unless in farm country or very low populated area or above 11,000gvw I think.) Then they test the gas caps after the sniffer. In california those of us with older vehicles are getting called into the test only facilities for our smogs and these are not high schoolers. Not to mention roadside sniffers being set up for the day in random areas. Now a question for the long tube headers what is the power curve like, because peak numbers look good but don't drive good generally unless the rest of the engine and drive train have been altered enough to really need them.
CA already dislikes trucks.. now they are starting in on older vehicles.. soon older vehicles will have to stay right and run 55 mph, or else they will put out too many emissions..I don't mean to badmouth CA..shoot I was born and raised there. but some of the things they do are overkill.

The y-pipe is also something that I can't do myself... I think you've got it bass akwards Mike
You'd have it done by now if you were motivated!

Also in this area, due to the ricers, Sacramento Police Department, Elk Grove Police Department, Citrius Heights Police Department, California Highway Patrol (perhaps my future job, man it's fun), and Sacramento County Sheriffs Department all perform stops on vehicles they feel could have modified emissions equipment. Special enforcement officers are trained to find non-CARB exempt parts. That is right down to fuel pressure regulators, adjustable cam sprockets, etc - this is on the news fairly frequently in this area. Also to that end, street racing often follows these vehicles which is another problem here.
I smogged my 96 F250 HD 4x4 460 today, and it passed with hardly any measurable emissions at 164k. The guys were blown away at the test station, as I was 10x below the state average and many times that more below the max readings. This is the second test in a year and my truck just runs super clean on both tests, and a bit more so after I did a recent tuneup and timing set swap.

I believe one of the responders to this thread said he had long tube headers that were smog legal units for california, please recheck as I have heard of them before as well, but if your budget is around the 250 mark for headers you really won't like those either. I do find that dyno numbers are very interesting the fact that just putting long tube headers on "bone stock" engine will give it almost 2000 more rpm. If it is "bone stock" the cam is hydraulic and the lifters will start colapsing over more than about 5500 rpm. Second with those ford "bone stock" cam specs you would have run into valve float past about 6500 rpm and long tube headers aren't going to help in that regard. Third your dyno chart doesn't start until 2000 rpm, what is going on below that because if you take your drive train numbers to tire rpm and gear chart you will find that 4.10 geared rear end with overdrive tranny is only turning about 2000 rpm at 60mph on the freeway. Back to what is going on below 2000rpm on the dyno chart since you are driving most of the time below 2000rpm. Forth point does your dyno let you choose which style of "shorty" header as there are more than one kind, unequal length, equal length and possible Tri-Y(not sure if considered shorty or long tube).
As for the headers you have now, go the state referee station and talk to them about your spec's sometimes you can get a waiver and your own reference number to the state if you pass the dyno test after authorization but I think you have to go back to a test only every year after that thou (not sure on the last part)
Point, unless you are going to put some high performance internals to this engine is the trouble of long tubes really worth it.
