CARB legal shorties

Forum geniuses,


What are your thoughts on JBA Ceramic Cat4ward Shorty Headers (11-14 GT)

CARB Certified. Best of all these JBA Mustang Headers are 50-state smog legal under Carb EO# D-57-27?

Not sure what your question is?

Do you want to know about JBA quality?

A lot of money for a little horsepower.

I guess I should have been more clear. Do you think that this product would be as good as a non-CARB shorty? I live in CA, but the car will be registered in FL. I may eventually have to switch registration to CA, so if they do as well as regular shorties, they would be worth the price for me.

I'm really looking for a lower growl from my 'stang.

If you're looking for a "lower growl," I would try changing the mufflers before switching to shorty's.

I don't know that JBA makes CARB legal AND non CARB legal. I think the only thing that makes them CARB legal is that they do not move the catalytic converters down stream at all.

But as mentioned above, shorties are a waste of time for the most part. The stock manifold is extremely efficient, only real gain in exhaust are from removing the cats and installing long tube headers.

Kooks makes some new shorties that are supposedly good for 10-15 hp... I'm very hard pressed to believe that but I cannot say for sure.
