I couldnt be any happier with them, Sounds amazing, Im all about power but after listening to this I dont even check for extra power, I just love listening to them, My setup is Kooks long tubes without cats and the stock TI, I dont throw much codes execpt P0420 H C and P0430 H C, is this because of Cats missing?

hey luis what happened? I was reading the thread where you were going with the LG LTs? What made you decide for kooks? I am in the same boat and have my heart set on LG's but hate the extra cash out i do plan to get cams later on so i don't know if kooks will help me later or the LGs :( tough decision

good luck with your setup though you need to bring it to the BK car show next sat so i can hear ur setup as well as Ed's.

MrKool,

I'm also shuffling LG LTs vs Kooks LTs in my head. The LGs are about 400 to $500 more expensive and I still dont know why are they more expensive?

Is there anyone who can tell us why should we (if we should) cough up the extra cash for the LGs instead of the less expensive Kooks?

Kooks are good headers. but they are not of long-tube design. Kooks headers are mid-lenght tube design. :cheers:

well from what i have researched it looks like that LG's do give you more HP but the main diffrence is torque LG's give atleast 10-15 more lbs of torque also i think with Cam install the diffrence between LG and non LG headers becoems even greater but i am trying to conforim all this in another thread but so far i am still looking.

It's the torque that really makes the difference. :thumb: And at least one site vendor who installs them all, has said they are clearly the best built headers out there. Now that does not mean the others are not well built, just that LG's are overall the best. Good Luck on your decision, hard to go wrong with either choice.

I was going with LGs for sure but I found a good deal for used set of kooks, From research I did stock set up Kooks or LGs would give almost exact results, some said the LGs would give 1-2 hp more below the power curve, But now with these responses you guys are making my stomach hurt :cry: because I wanted the most power out of it as I could, but as long as I get 380rwhp I'll be happy :yeadog:

Amen! Borlas will wake things up!



Congrats on the headers. You're going to love them. :thumb:

I love them already, Borlas wont do it for me, quieter for me the better, my setup now is just a bit louder on start up then stock, After a minute it actually gets quieter (smoother) sounding then stock, at cruise speeds it's quieter then stock, at WOT anywhere it is WAY louder, but WAY better, I cant believe how much better it sounds :yeadog: I was just looking for power but after I cranked her up I havent stoped listening to the sound

To make u feel better, many of the drag racing guys I know run kooks headers.

Couto1981 -

I could not agree more. Kooks are simply the best headers on he market in terms of quality and performance.

Here are my Kooks 1-7/8" on a 427 C5R: :guiness:

I hit 390 with the kooks 1 7/8ths, catless, vararam (I dont think it does anything on the dyno), and a pulley.

The car sounded AWESOME with the TI catback and the headers/off road pipe. Try a rev matched downshift into the 4k rpm range, and let the car deccel in gear. The pops and bangs are intoxicating.
