[Compcowboy]

SHIM! is the route to go.

 

[bg6.7cummins]

compcowboy. are you happy with your h&s?

 

[atc250r18]

YES HE'S HAPPY! Are you new? :rof He's had nothing good things to say about it as far as I can tell. (don't mind me comp workin on a 6er). Back to the question, use the shim kit whenever you stack. Don't want to crack your rail.

Yep use the supplied shims when stacking:thumbsup

 

[Compcowboy]

Yes, i have had no issues with my H&S kit. Not going to upgrade unless an EGR fooler is included too.
