hey i just baught a full cattman exhaust from header to the muffler i was wondering what else would i need to by to properly tune and install it thanks in advance

 

I would say some tools would help. So, you got Cattman headers? That's

 

gaskets?

reason i asked was b/c someone told me that i had to get 02 simulators and a vafc-II

 

Typically, Cattman includes them.

 

In order to get the most out of the headers, yes, a VAFCII would benefit. As for the O2 sims, you would only need one, (single output) and it would only be if you don’t want a CEL.

 

thanks alot

 

Sweet exhaust!

 

POST PICS 10 cahrc

 

I just bought the same exhaust set-up a month ago and it is all installed and everything. I bought an 02 simulator right from cattman and I didnt install it right away mainly because I wasnt get a check engine light, so then a couple weeks ago I decided to install it. Install was perfect, everything were it was, red indicator light blinking slowly like it is suppose to do and then after a little drive I get a check engline light. It is for the rear 02 sensor, so we clear and then try again and it comes back, we dissconnect the 02 simulator, and I get no check engine light. I am not sure what is going on with it but it works for me and everything is fine.

Sorry to hijack but just a quick question what can one expect from getting a VAFCII and tuning the set-up?

Thanks, you will love this set-up, louder than stock but still a nice sound, and the gains are very noticeable and much quicker.

Check the AM foum for further information. As for the CEL, check the codes and see if it is indeed the O2 sensor.

.. ........ Keep the sensor in there, mine never gave me a CEL.
