What's the difference between LT headers and shorty headers?

kinda. might be like splitting the difference. I've been considering this route too, since I live in VA, and don't want to eff around with being catless and being screwed when it's emissions/inspection time.

I'm in the same situation here in CA. I wouldn't mind going catless, as long as I have an easy fix should I get a fix-it ticket or have to get smog tested. Luckily, I think we only have to get smogged every 5 years but I still don't want to take a chance. Getting the MAK Cat deletes would allow for super easy swaps between the stock cats and the delete pipes as long as flanges are welded in the proper spots. That and I've heard that the MAK Cat delete pipes make the car sound like it has headers and they a third of the price.

I just moved to NoVA/DC from Los Angeles, so I understand your pain 100%. When we moved out to California in the first place I demodded my '13 GT a bit to be quieter, because I feared the retribution of the CHP.

So how much of a power difference is there between a catted and non catted long tube headers? I m considering ARH or Kooks Green Cats!

About 5-7RWHP difference with the advantage going to the non catted LT's.
