im having a shop punch out my cat and put a o2 simulator in to avoid a check engine light, is $75 a good deal on the simulator and its install? not including hollowing the cat.

 

Why not spend the $140 and buy a high flow cat?

I found this with a quick google search...

you should be able to pick up a simulator for around 40 bucks

 

i have an ultimate racing 3'' highflow cat. Im gonna punch it out. If i punch out the stock cat the flange would still only be 2.5 inches or whatever the stock pipe is.

40 bucks for a simulator? Where?

 

www.buschurracing.com sells them for 45 i believe but you have to call.........

 

BPClements told me he took some spark plug anti-foulers, found in the help section of Pep Boys. He drilled a 1/2 hole on each one (he used two). Threaded the O2 sensor into them and install in exhaust. Hasn't got a CEL in over 500 miles. Cost less than $10.
It's the same theory as a deeper O2 bung, takes the sensor out of the direct exhaust flow.

 

thanks for the info guys.

 

Why nto jsut buy the Ultimate Racing test pipe for $70.00, and have the best of all worlds? A high flow cat for street, a race pipe for track days, or drag days, etc, and NO CE light at all

As usual, Adam beat me to it...

 

I did the drilling out of the spark plug anti-fouler and it works great. No more CEL.

can someone do a how to on this? im sure I and the rest of the forum would really appretiate it.

 

yeah but if u punch out a highflow cat, u can have the power of a testpipe ALL the time without having to switch.

 

Don't punch out a perfectly good cat. Those will come in handy come smog check time. Get one of these!
