I run the Kooks Super Streets headers, (shorties), as I wanted to keep my OEM cats. They were the last exhaust mod I completed and I too really like them. I run a NA setup with OEM TK and I can say that the shortie headers really brought everything together to max my other exhaust and CAI mods. It was a noticeable difference.
I've learned that the U-Code responds very favorably to exhaust mods, much more so than CAI systems. But nice having both. Next up I'm thinking about going with Hi Flow/Hi Performance Cats. Want to keep my Boss 50 states emissions compliant.
Most on forums will say LTH only and if you are going FI down the road, you might want to look at the LTH. But, I would say listen to GHIGBoss302's recommendations because a 447 RWHP 13 Boss 302 running 11.6ET's at 119MPH in the 1/4 is hard to argue with!
Good luck and keep us posted,
302 Hi Pro
