i say 300 to 310.

My goal is somewhere in the 300-310 range. Will an O/R X-pipe with the stock mufflers really be that much louder? Are we talking like SLP LM with cats loud?

I got 311 RWHP and 328 RWTQ on JBA's dyno after they installed a Steeda CIA, tune, UDP's and CMCV deletes. No exhaust work. See dyno graph and what you will be taking out of your induction system.

Note that not all CMCV delete plates are created equal. Some are just old plates with the butterflies removed. Others arenew casting with improved air flow, see Steeda's website for explanations of both.

the only difference is that the chepaer ones were made by ford, u can buy "steeda economy plates" and when u get them, theres a writing in each of them FOMOCO and other numbers also.
The expensive ones are real steedas.... i'm sure the airflow is the same.

I've heard that the difference between the Steeda economy plates and the more expensive ones is negligible. But the more expensive ones do have nozzles for nitrous.

Thats a video of the stock mufflers/headers with an O/R X-pipe. Maybe its just me but that doesn't seem that much louder.

You are correct, they are not billet either but that is rediculous anyway.

That sounds good, but would sounds better with an o/r H-Pipe.
