I'm new to Diesel's

I was told to install a S&B Cold Air Intake and cut out the Cat

Is this a good option

i don't want to install a programmer yet, i have 2 years left on Warranty

 

2 years left on your warranty - and you want to keep it - better leave that CAT in place. In fact check with your dealer if you can even install the CAI.

I bought my truck in Cochrane and at the time they were very much pro aftermarket but I'm not sure if they still are.

Check to be sure.
