ok, i got a guy that is willing to build me custom long tube headers to come off the block. outside the frame rails, and long tube, so then i can put them down the sides. and holy crap true duals.... and i saw a boggin truck with this setup and it sounded amazing, but no cats, so it wasnt street legal...

anyone know a way, i can run these true duals on my 98, and pass emission? meaning some how either make the computer thiink the cat is there. or a way i can wire them both together... or i will even open this up.

anyone know a way i can get long tubes and trueduals under my truck?

 

True duals? yes. Not cat and pass emissons? No.

 

run a small cat on each one, and put the o2 sensor in one of the headers, or lead pipes
the only problem there is if the other side of the motor has a problem, it won't detect it

 

im running longtubes also, and i have to run powercats check that out !

 

power cats... please explain.. i am not to good with this part of my truck, suspention is my specialty

 

well i orginally had a magnaflow highflow cat on, and that wont work anymore due to putting longtubes on , my exhaust guy says i need to run smaller cats and he showed me in the summit catalog i need something small too fit and i need 2 , but i didnt have the cats at the time so right now im running with no cats but these are them, will be ordering these and just running duels with them with no mufflers http://www.summitracing.com/parts/DTC-79-400250/

man, you need that

what I mean in this picture, is that you need a section of the pipe to be like the nº 8 thing.... I will make a draw of it to you understand because my english is not soo good

 

so, when you are in the street you have to use the straight pipes, but when you need the emission test, you put the cats... when you passed it, just put again the straight pipes.

I don't know whats the name of thing that is in the end of the headers... where you put the bolts,.. you will need 12 for the whole thing :O

thats my 0.00000000000002 Dx

 

would it be uneven backflow because there is 1 cat on one side and not the other , and it would sound diffrent

 

man you didn't get it... You have to have in both lines... the same things! cats with cats and pipes with pipes...

It's just a draw to show the idea only... obviusly you wont have a cat in one side and the other straight pipe ¬¬
