I have a 93 bronco w/351 EFI. I plan on putting true duals w/ headers. I have 2 dynomax mufflers and am not putting cats back on it. Is there anything bad about not running cats besides echeck. What do I have to do to get this running correctly. Any and all help is appreciated.

thanks

Personaly I would not do the duals. if you are looking for performance remove the cats if its smog legal and go with a single 3" system, or you can come off of your head pipes with 3" pipe into a single 3" inlet dual 2.5" outlet muffler that way you get the dual look. i had duals on mine when i got it and after i put the 3"in system on it i was surprised with the power gain. enjoy im sure some one else will chime in sooner or later with more thoughts.

 

I'd just be concerned with all the pressures being equalized and all. Run 'em out the sides before rear tire. -wb

 

i put true duals hedman hedders and glasspacks no cats , stainless stell tips on my bronco. i noticed a big horse power gain and they sound bad *** , and look cool i recomend duals man go for it \m/

 

what about the o2 sensor??? how do you get around that, my 88 has only 1 sensor that goes in the cat.

 

I don't have one in the cat, I do have one in the y-pipe. To take care of that you just run a cross over the same distance from the block as the original.

 

go to my gallery and look at my tech pics and see how i did mine maybe it will give you some ideas. DW

 

Single 3" is good enough. Why go to the trouble? Because Mustangs have it? Single 3" is cheaper and sounds just as nice. Mine sounds amazing. Never thought of duals. Seems like too much work and $$$ for what you can accomplish with a well thought out single system.
