Install an X pipe

And this magnaflow exhaust

I'm thinking this will sound pretty good, Im driving a 2001 Dodge Ram 1500 5.9L 360

I need to know if there are any o2 sensors behind the cat... Otherwise I cant cut it off...

 

besides the fact that you could easily look for youself in 10 seconds...

yes theres one behind the cat. removng it wont affect anything but it will through a check engine light, so you can get an O2 sim or just weld an O2 sensor bung into the new pipe after the cat

 

So an o2 sim is something I would just plug in where the old o2 sensor went??? and it tells it its getting a good reading.....

 

yes.

 

Inresting... Thanks!

 

Anyone know where I can locate one of these o2 sims.....

 

Fastman. The guy that does the Throttle body mods.

 

If your computer is a smarter version, it won't like the O2 simulators because it can do a system cycle check to see if the voltage cycles with it. And yes it does affect your gas milage if you don't have a downstream O2 sensor. Summitracing is the easiest place to find an O2 simulator.

 

how does it effect gas milage?
