Hi all,
I would like to appologize for my poor English

I'm a frenchy guy.
I have a L99 with stock cat back and noweeds cut outs. I plan to buy 1-7/8" ARH short system with high flow cats but I want to keep my cut outs and my stock cat back.
Do you know if is it possible ? Is there a problem with cold air flow that comes from the cuts to the engine ?
Thanks for your help.
