So im looking into starting to upgrade my boss finally after months of having it .im looking at headers right now and i couldnt find anyone on here running those same headers? All i want to do to the car right now is a CAI, tune, and exhaust, eventually im going to upgrade the trans, then put a kenne bell on it.

I personally think long tubes arent worth it. Not for a couple extra ponies compared to shorty headers. I personally run kooks shorty headers for our cars. I love them and im all N/A . WIth my mods i put down a nice 447rwhp and its MORE than enough for a street car. After my experience with 2.2 kenne bell on my last mustang (600rwhp 99gt) i would never get another one of their chargers again.To much hassle compared to other choices out there.

Nice! i had found a great deal on the headers and h-pipe so thats why i was thinking of just going that route, as for the supercharger, ill have to keep doing my research, it'll be a little while longer til i go for it, i want to drive it around and enjoy it more right now!

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,

Not saying a supercharger isnt nice to have. Just more headaches and more stuff to upgrade. More chances of things going wrong.

I mean a good charger on a boss is 700+rwhp easy. But for a street car, thats a waste who wants a car that needs drag radials just to drive it .. With a few minor mods the boss will wake up and really impress you. Even without a charger.

I can read between the lines and can see that every Boss has potential for a sub 11 sec. 1/4 mile here. Except mine, yes can understand too that driver error makes the difference. Now recall when Bossy13 installed his Kook's shorties and driver side was off alignment by less than an inch I think it was. Contacted Kooks and he actually had them change their welding jig and sent him an upgrade. So how many sets of them were sold before or after with this imperfection? Guess the shorties connected all right prior too, but not the same position as OEM.

Was always under the impression headers were supposed to have equal length tubing for scavenging action, creating a harmonic pulse balancing effect with a low pressure (vaccum) action taking place. The tubings themselves assisting to extricate the exhaust? Have read nothing but praise and power gains with the unequal length Kook's shorties in use. Jury's still out on this one, just so much conflicting info makes me skeptical.

What did Ford have in mind with their tri-y's? Is this a best kept secret and certainly way different configuration from Kooks shorties? Why didn't Ford use the unequal length shortie version, monetary wise wouldn't think they'd be any more expensive? The after market parts industry is booming now a days but these must be good for something I'd think?

Yep, they are good for 444 HP at the Flywheel and around 372 RWHP (+/- 3~5). The OEM are actually very good for high volume mass produced headers, but take a close look at the pics you posted. Notice anything about pipe diameter consistency?

One thing I know for sure is the Kooks Super Street headers when install with Silver Ceramic Coating sure looks good under the hood.

Bossy13 did an excellent job of documenting his header and exhaust system install in his Exhaust Make Over thread.

Oh I think the Kooks are awesome O2HP and the design is such that I wouldn't be surprised the appearance of long tubes being such tight quarters and especially ceramic coated. Looking in the engine compartment from an overhead view (maybe not quite birdseye) is what I'm picturing.

Those thumbs are photos I just saved, put on here before. But my point is the things aren't just haphazardly assembled but in a certain configuration with certain diameter tubings. The Kooks sure aren't thrown together either, I'd say completely different theories of exhaust expulsion in competition here. I find it nice to know the whys and how's, then make an informed decision based on pros and cons. But what fun is that?

The tri-y's to me appear as one cylinder at a time is firing and the Kooks all 4 simultaneous. Believe variants of this topic has been covered time to time but I can't ever recall an answer. Too think I tried looking this up to no avail, better luck next time.

Hey, Rich B:

Very good points on the pulse theory. It would be interesting to see what we would get if we crossed the two. Meaning use the Ford Tri-Y design with the Kooks manderal/hydro bent round tubing. That would be interesting, I would think.

On a side note, they have some darn good welders in North Carolina.

Have fun up there,
