The metal tube runing from the back of the engine block to the main cat, is it needed? reason i ask is cause my cat has a hole in it and i wanna replace it with a str8 pipe and block off that tube.

Can i get away with this w/o a problem?

 

you can get away with it if you are replacing the cat with a straight pipe.

that tube is called the split air pipe, and it can just vent to atm, you dont have to block it off or anything

 

will the sound of an exhast leak be heard if vented? will i suffer a power loss?

 

also if i block it will i **** up anything?

 

i got the 3557 (or whatever) block off plates doesnt it come with aplate to block that off anyway?

 

Do a little searching and figure out what it is before you go yanking it off or venting it (wtf purpose does that serve? Guess you wouldn't know unless you read up on the subject).

And yes, the 2571 Engineering plates do come with a split air block off. Again, another reason I suggest you learn before mucking around in your engine bay. That will result in no good.

 

LoL, man I searched. Half the time people say search all we get back is mombo jombo that doesnt cover what we need.

 

**** man, im sorry for the semi rude responce. I just reread my first post witch i had to retype due to IE being a POS, i know it controlls the aux ports i was wondering if

1. the package i got came with the plate to block that off.

2. if i could just zip tie them open and suffer only low end loss. witch is fine cause n/a's are slow as *** off the line.

 

ok so i removed the main cat and replaced it with a test pipe, and my 5th and 6th ports feel like they are still opening/

 

they arent.

go read on a way to actuate them semi manually (electronically)

 

your right, i was just feeling what i wanted. tomorrow im doing the smog pump way of opening them
