can i run with my smog pump still connected to my headers but not connected to my cats? im redoing my exaust with no cats...would this be a problem

 

Well I can tell you what I did to my 88 L98. My car is a bone stocker and first thing I did was remove the cat converter, it has a pipe running to it from the smog junk. I knew I was not leaving the smog junk on the car for long so I left the pipe under the car for a short time, it just blows air into the system, I honestly could not even here it unless I stuck my head under the rocker. I guess you could plug it off but I am not sure what adverse affects it would have on the rest of the system so I left mine open for a few weeks until I got the time to remove the rest of it,,,I had no ill affects from it. I have since removed all the smog junk from my car so no more hoses and pipes cluttering up the bay. I am sure there is a solution for that small diameter pipe that runs to the cat because alot of guys on here run aftermarket high flowing cats and I beleive that most of them do not come with the connection for this tiny pipe. I could be wrong though as I am not completely up on whats new on the smog front because I have never had to go through any of that smog testing so I really don't care to clog my mind with smog knowledge Larry.

 

Yes but you might as well remove the whole system.

 

i wasnt sure if i ran like i said above if i would hurt anything, i will be removing them

thank you

 

I belive some TPI applications due rely on some output from the AIR system. There is a sticky in the exhaust board that you should check out. I only know that is has zero effect on TBI cars.

 

Shifty Capone is correct, there is mention of this I believe under smog pump removal, but you have to do some reading for a while to find it. I went over that myself trying to decide whether or not to remove the smog, Even though I wanted it gone no matter what I feel this stuff is worth reading over.
I don't understand it completely because I don't burn my own chips yet, but those that do make mention of removing the smog pump causing a lean condition, it can simply be remidied by burning a new chip. Some people mention installing an adjustable fuel pressure regulator and turning the pressure up slightly to compensate but I think the general consensus is to burn a chip to do it correctly. I have removed all my smog equipment but have yet to burn a chip or install an adjustable regulator. I have not noticed any ill affects, the car runs strong, but I still plan on chip tuning when I get the time. There are many people on here that do the same with no codes, no ill affects at all so I decided to do mine before I was ready to play with chips. I do feel the car acts a little lean when cold, just a hunch but nothing that causes any problems. Soon I will do chip burning and the usual bolt on stuff etc...Read over it and make your own decision, plenty of usefull info in here, goodluck, Larry.

 

yeah my bro did it to his and it did'nt do any thing

 

I just removed the drive belt from the smog pump and I have no problems at all. The reason I don't remove the smog pump is becsause of smog checks every 2 years.
