Longtubes and emmisions
 

I am going to start doing some bolt ons, and I was wondering if longtube headers ruin emmisions even when you are running cats? is is possible to run cats with LT's?

RE: Longtubes and emmisions
 

Yes you can run cats with LT`s. As long as your CEL isn`t on and they don`t do a visual inspection, then you should pass.

I am also curious about this. I've heard it both ways, it will and it won't

RE: Longtubes and emmisions
 

what he said is right it depends were u take it and if they do the vis and if you are throwing any codes but if you have it setup right you will be fine

RE: Longtubes and emmisions
 

techincally no... in NC longtubes are straight up illegal... the good news is that unless your in california nobody actually looks.. I welded in a diferent lookin section of pipe... "they are high flow cats" ;) just in case... but as long as you dont have a check engine you will pass emissions, I dont know what state your in, but unless they put it in you pipe you should be good - and even then 99% of cat less modern cars still pass. so basically dont worry about it

So your in NC bransdaman? I am too, good to hear that most places don't look :D

I want to get the full SLP setup

RE: Longtubes and emmisions
 

I'm in NC, too. I'm a tech at a Ford dealership and we only check stupid things like lights and if the car has cats. I'm new to NC and I had no idea that LT's were illegal. If you get pulled over, could a cop give you a ticket for having them?

RE: Longtubes and emmisions
 

im from ct and i run an emissions station and we do a visual check and if ur check engine light is on u automatically fail. as long as theres a cat the visual will pass but no cats = fail

RE: Longtubes and emmisions
 

how do u prevent the check engine light from going on after the install? I am looking at getting BBK LT's and which as I understand hook up to the cats right ?

RE: Longtubes and emmisions
 

when u get long tubes u need a new mid pipe that works with the longer header and u would get mil eliminators to keep the light off with out cats
