Do I need to delete?

[Ches-b]

I was in the shop today and was looking at a mini maxx, exhaust, s&b. The guys at the shop were telling me that I don't have to delete my egr....I know with the mini maxx you can shut the egr off, but is there going to be issues later if I don't remove it?

Also, I'm still deciding on 5" exhaust or dual 4" any opinions or pros and cons? Thanks!

you dont have to delete. it may cake up your egr valve and you will have to clean it or replace it when u return to stock. another option would be to use block off plates which would basically do nothing more but keep the soot out of the intake and from caking up your egr valve. the full delete keeps the soot out, and keeps the flow of coolant out of the egr system.

single 5" may sound a little deeper but 4" will spread sound around more i think. but its not a huge sound difference so pick which one u think looks best

What Travis said. Its not absolutely necessary, but getting rid of it and the coolers is the best option.

Tough call on the exhaust. Most people seem to go with a 5" kit. 4" duals does look and sound good though too. The only drawback to duals would be clearance if you run a GN hitch.

I deleted for a piece of mind that the coolers them selves wouldnt go bad. I ran around for 60k miles with my EGR turned off with no issues before went ahead and did a full delete.
