so I when I got tuned, I had 1 cat left on my car... and my WOT afrs were good,..

iand just 2 days ago I put on a straight pipe. and I was wondering if that by removing my cat it would possibly mess with my AFRs ?? and possibly mean that id have to get re tuned?

 

most likely won't make a drastic change. only difference may be faster spooling and perhaps idle may be just a smidge off. I'm thinking of doing the same thing.

 

sure.. "im happy with my car" hhahaha.. soon it will be.. o im just gonna buy a boost controller.. then mike.. wanna help me pull my motor for this brian crower stroker kit!
LOL!

 

alright sweet,

actually now that my cat is off my car now idles at 14.7-15.3

also when I still had my cat on when I hit WOT my afrs would pin at 10 and now they are between 11.3 - 12.0

my car has only stalled once since I got rid of my cat. , so by deleting my cat it has pretty much cured my warm start up stall problem and also has solved my bad idle hunting problem.

glad to hear everything worked out. now i can try it hehe

 

Are you hitting more boost as a result of the new exhaust? Sounds like it.

 

Getting any CELs?

 

your WOT afrs looks better now without a cat
