I'm aware of these threads, I saw the "deleted second cats and got 12.77 whp" or whatever it was, I'm asking if anyone has cut off their mufflers as well, basically running straight pipes after the first catWhat's with the recent "i wanna delete my secondary cats" threads? Do a search and you will be over whelmed with information.
Also, you won't be able to pass California emissions. Dinan sells straight pipes but makes no power improvement claims - they do show more hp and tq with their high flow mid pipe.Thank you for the heads up, I figured this would be the case. Wouldn't the top end increase though with a large sacrifice for low end though? Instead of being a complete power loss?
