Has anyone dynoed before and after long tube headers and cat removal?


My difference was about 35 hp...but it was over three years ago...so my memory may be flawed...

Part of california's smog inspection is visual. If they don't see any cats it's a instant fail. Then you could be ordered to a smog ref who will then scrutinize every aspect of you vehicles emissions system. And pretty positive our trucks will not pass the sniffer with no cats.

Got to remember that California is the strictist state when it comes to clean air. Hence the term 49 state vehicle
 
Please post an engine pic with the headers visible. The Mopar tubes must add some bling to the engine bay. Thanks!
 
Update: I noticed that I Lost some torque on the bottom. But gained it back in the mid range and top end. Also gained 1-2 mpg on the freeway. 13.8 mpg @ 65mph

Yes i believe the shorty headers give more low end, And the LTs what you are seeing, Mid to top end. Enjoy.

I guess I don't have any from the bottom...

The second pic is prior to Justin doing my valve covers...

Be sure to get the headers coated before you install them...JetHot did mine.
