Tomei UEL Catless Header
 
Before making judgement understand that I'm aware almost everyone and their mother has installed this header on their twin but I cant seem to find any threads talking about this.

I'm looking into investing in one very soon. My question is what could happen if I were to DD a catless header w/o a tune? I have heard that the engine may become choked due to the gasses recirculating back into the cylinders due to the second cat becoming clogged(?) Not sure on the validity of that statement. If I were to buy the header and swap out the old one, it'd be a while until I'm able to buy an OFT.
