Okay me and my buddy put Mac headers on my '99 Trans Am this weekend and we got both headers in from the top. I just wanted to know if anyone else has done this.

Also my car has thrown an ses code and I checked the wire's the all seem to be on fine. I am running a y-pipe that is open on the driver side. I got cats on both sides any of yall have any advice for me.

 

Go to an autozone or similar place and get the code read.

 

Do you mean that your Y-pipe is not connected to the intermediate pipe? If this is the case then the reason for the code is the O2 sensor have caught on to your plan to polute the air with carbon monoxide,,BWAHHHAAHAHAHA (Evil laugh)


Just kiddin , but I do think its an O2 sensor problem.

 

How would that pollute the air? The cats are on the y-pipe before it even gets to the i-pipe. Bypassing the muffler doesn't pollute the air.

 

Yea I fixed the miss but then it threw another code tonight so I gonna go buy a cheap code reader and find out what is goin on

 

Kyle,

Hence the phrase......Just Kiddin.

Aggie mentioned an open Y-pipe, not i-pipe though.

 

Well the driver side of the y-pipe is open
