Aftermarket headers

ok so i want to get some performance headers, but i dont know which heders to get. i also have a few questions about the headers.

#1. JBA and doug thorley headers; are they able to pass smog?

#2. are the resonators on the stock headers removed? i know theres one resonator on the driver side header before the cat, and two on the other header.

 

I have no experience with headers, but I have heard nothing but bad about JBA.

 

if u have a good welder then jba are great esp with emission testing. i really did feel a difference when i got my jba and did them right. if u take ur time and port them out the outcome is great. but of course ull get the most power with the long tubes. but i just wanna throw it out there cuz lots of people hate on jbas and its cuz they did a shitty installation job.

 

well it depends on what ur running. if I4 or V6. Doug thorleys are great either way. pretty much just bolt on. they are mainly for low end power though. aroud 3000 or 3500 rpm thats when you really feel it. oh yes DTs are 50 state smog legal.

 

im lokin at the DT headers and i cant wait to get them, now all i need is the money, life of a college student = broke

 

what do headers do

 

Marioso, headers make the exhaust flow easier, an engine is basically a air pump, unrestricted air flow in and out makes it more efficient. Due to costs auto manufacturers do not always give you optimum setups.
This is why "cold air intake " and header and free flowing exhaust pipes and mufflers are offered by the aftermarket dealers.
Its an old hot rod trick.
You should always stick with the top names , which include Doug Thorley, Garret Air Research, TRD and many other tip notch names.

 

hes right

 

ok gotta admit. im not toooo header smart myself.... i no some are weld on but are there any that bolt on to either factory or aftermarket exhaust.

 

CornDog, love the color of your truck, I tried to get my truck in that color but none were available unless I wanted to pay quite a bit more, as some trucks in Speedway Blue only are available( in New England) with the hood scoop and expensive options.

The exhaust manifolds that are attached to your engine are the actual "header" you see them on lots of hot rods and they often call them "tubular headers" the factory headers are generally cast iron due to cost limitations.
There is quite a science behind getting the headers to flow correctly and often when some one puts a new set of headers on they are often called "free flow header" meaning they have less restriction and usually a pair of larger diameter exhaust pipes are used and free flow mufflers , all of these combined with a better intake system means higher horsepower and usually as a consequence a much nicer sounding exhaust system.
Expensive exhaust pipes can be very expensive , for instance the "headers " on a Formula One Race car are hand made and take hundreds of hours to make and the cost is in the tens of thousands of dollars and they are made out of very exotic materials.
I hope this helps ,

thanks jeff i appreciate the help and the comment too. i love the color too but the only prob is i couldnt get the long bed with a maual trans. so i had to settle for a short bed. thats the only draw back i had. thanks for the info......

 

TacomaKid, I believe that all of the good exhaust companies, can make and adapt headers to pass emissions for various vehicles.
If you find a dealer, go visit them when they are not busy and sit down with the tech people and bring all the spec's with you...... considering all of the different requirements for each state as far as emissions I am sure they are adaptable.

If your worried about the smog test and dont wanna change the aftermarkets for the stockers then I'd go with the shortys. JBA or DT will work but your gonna have to cut the cats off of the stockers and weld them on to the aftermarkets. Just make sure you go to a reputable exhaust shop.
