I need to know the distance the passenger side upstream 02 is from the header on a ls1 camaro (99 if it matters). Also the distance from the cats to the downstreams would be nice as well. I am looking for actual lengths. Please help.

 

Bump.... I really need to know , someone on this forum has to have their camaro on jackstands for some mod.....

 

Bump..... If you tell me I will be able to drive my car... everyone on this forum must know the pain and suffering of not being able to drive their car.

 

Bump please please help.

 

Bump Bump I am ready to roll except for this.

 

Bump bump

 

never did measure it.......but the stock length plus a 19 inch extender did the trick on my headers......not to short....not to long......on both sides..........it seems that with the the stock manifolds there were 4 diff lenghts

 

are you talkinga bout where the O2's go into the pipe?

just put them right after the merge on the collector. if you have longtubes you obviously cant get them at the same distance as stock.

if you want a reference just look where the bungs are welded on this pic...



hope thats what you were looking for

 

the 02's on a set of long tube headers is where the collectors are like in the pic above.
only headers that dont move the 02's are shortys i belive and those arent even worth it on our cars.
