If long tubes are installed and installed with an H-pipe with Cats it should still pass emissions right?

I read somewhere that they wont pass?

Thats incorrect, right?

cammedlx

they should if they still have all the provisions for the A.I.R system in other word it the smog pump is still working then you should have no problem

where i live, there is no emissions legal long tubes. its short tube or stock manifold

So as long as there is room for the smog pump tube to get to the cats?

You "might" be able to pass the sniffer test, but you won't pass visual inspection. One of the reasons longtubes are illegal emissions wise is because the 02 sensor gets relocated farther from the head, slowing its response and thus increasing emisssions.

No Sh*T... so I live in ohio... where we ned to pass emissions test (obviously) and I just won an auction for Long Tube headers and catted H-pipe. So if I install them, then my car will no longer pass emissions?

Man that would Really suck!!!!

vfast

why bother with them..they really pose no great hp increase.....I believe the step shorty header works better

i agree with vfast, why bother... but you can mail me those headers and h pipe if your not going to instal them

Dont they add like 8 more horses?

I got them cheaper then any Brand new set of shorty's.

And I am rebuilding the whole car.... and right now I am buying peice by peice. So I imagine it wont be to hard to install.. Seeing everything will be out

Long tubes are gonna give you the best performance. Its a mod that can grow with your vehicle. The sound of long tubes and a good aftermarket exhaust are just about unbeatable. Shorty headers are gonna perform just about as well, while also allowing you to use a catted mid-pipe for those stupid *** emissions tests. Its funny how back in the day they tested nuclear bombs, cleared entire forests, strip mined out the countryside, but now most people cant even turn their cars on without having someone check it to see if its ok for the envirnment first. Buncha BS if you ask me. I love my off-road midpipe .
