No cats will add better power in combination with Long tube headers. With your mods, you might see up to 5hp gain. Plus without a tune you'll lose TQ down low and gain high in the band only.

Stroked and blown

Hi flow cats or green cats don't like boost. Boosted motors burn up cats . I too like the drag strip smell. No cats are free. I am a big fan of the cat delete. At least with my car, nothing raspy about it, matter of fact the exact opposite is true.

You will most likely have a cel with hf cats and long tubes as well. That means it won't pass inspection(in most states). If you tune it it will void engine warranty. Double edged sword of modding the engine past cai and catback.

 There's no point of just getting hi flows. It's not worth it.
