Re: LG vs. Kooks vs. Supermaxx (rplaster)
I like my 350.4rwhp/363.8rwtq better. Plus, looks like my dyno graph has a better flat curve which equal low & mid power gains. Compare the blue lines on both graphs. Oops, hope I did not start a flame war.

I know some think this topic has been beaten to death, but to those of us who are looking for information to help us decide which header system to go with, this and the other thread currently running have been a great source of information. Gotta luv it :yesnod:

Oh damn... That makes this a LOT more interesting...
Back to my previous statement:
Now the question: Which car had which mods?
Cary's car had a cat-back, the other did not
Cary's car is a '01 (350HP, 375 TQ), the other one was a '00- (345HP, 350TQ)
Cary's car had a Vortex, the other car had a stock intake.
Given those aove criteria, I would say the Kooks are at least as good as the LG's. I would like to see a dyno with data down to 2000 RPM to be sure, though... :lurk:

Re: LG vs. Kooks vs. Supermaxx (James G)
I was almost settled on getting the LGs prior to these recent threads...now I'm strongly considering Kook's.
1) Does anyone have photos of spark plug access on the LGs, 1 3/4" Kook's & 1 7/8" Kook's? The 1 7/8" would leave plenty of headroom for future mods, but I'm hoping that's not at the expense of burnt boots or making plug swaps a PITA.
2) Does Kook's make specific versions for early & late model C5s, or would I have to swap air tubes like the LGs?
3) Could someone post a pic of a Kook's off-road x-pipe...I'd like to see how it necks down from 3" to meet up with the 2 1/2" cat back section.
Thanks,
Rob

Re: LG vs. Kooks vs. Supermaxx (FRC Rob)
Kook's makes C5 headers for specific years. Not that we're concerned about torque figures below 3000 rpm but why does it really matter who makes more torque at an rpm level that's reserved, for the most part, for cruising. Anyone pounding their C5 down a drag strip, a highway or even a road course spends hardly any time at those rpm levels. We're not pulling trailers with these cars are we? It's been pointed out many times that Kook's headers perform extremely well at low rpm's but what separates us from the rest is that you won't be sacrificing any performance where it counts, 4000rpms and up. The other significant difference is that you have more than 1 choice in header and exhaust sizes to suit your cars specific needs. Nick "Kook's Headers"

Re: LG vs. Kooks vs. Supermaxx (nick filippides)
Not everyone is building a race car here... My car is a street/autoX car where low end TQ can come in handy. There is no point shifting into first in autoX to get back into the powerband - 3k rpm TQ in 2nd gear comes in REAL handy.

As well, big torque at low revs is what puts smiles on a lot of folks faces, so even if it is less important for (most) racing situations, don't discount it as an important "grin factor" thing that folks will key on.

Re: LG vs. Kooks vs. Supermaxx (Umrswimr)
:iagree: For the strait line guys less torque is ok but for us who autocross
and solo trials torque means fewer shifts between corners and more controllable oversteer. :thumbs:

Re: LG vs. Kooks vs. Supermaxx (James G)
Perhaps some of the tuners who've dyno'd our headers in all forms can post their findings. Our headers have spent countless hours on dyno's across the the country in recent months and I'm sure this information is out there in abundance. I can tell you one thing for sure, if torque is king at or below 3000 rpm in the form of racing you enjoy then you might as well leave your stock manifolds on because even they will do a fine job making torque at those rpm levels. If you want to make more torque than your tires will know what to do with then go Kook's. We've got a system available to cover any form of performance driving your C5 experiences, from bone stock auto crossers to blown 800 plus hp strokers . Nick "Kook's Headers"

Re: LG vs. Kooks vs. Supermaxx (nick filippides)
Well...after all the pissfests of who makes more power over the course of the last year I've been watching the forums and trying to make up my mind...I think for the extra $500 (LGM) I've finely ruled out the LGM's. They're a beautiful header, make good power...but for $500 I'll have my clutch I'm saving for a heads/cam/headers package. Limited to the SuperMaxx and Kooks 1 7/8 now. So...let me research another year while we all argue about it. :cuss :lol:

Re: LG vs. Kooks vs. Supermaxx (SideStep)
Whats wrong with your stainless works headers? I have never heard one person complain about those before.
I repeatedly get code P0133 and P0153, Heated Oxygen Sensor (H02S) Slow Response Bank 1 Sensor 1. I have tried new sensors. I have put rear sensors in the front bungs and connect to the front sensor harness with the adapter that Lou sales. There are no leaks. My Air-Pump is working fine.... NOTHING works... :sad:

The LG headers are great once you get through the installation problems that many of us have experienced. The increase in torque is incredible - look at my numbers in my signature.

Re: LG vs. Kooks vs. Supermaxx (AlohaC5)
Ah-ha so You fixed the issue by using your fronts after all. Now I have to buy the extensions -- I wish I could return these adapters.
I'll definately try my fronts before I buy and Install new rears sensors.
This sux man, I wish some of you monkeys would buy the LGMs and have this problem and then figure out a cheaper solution.

We will put the LG Pro Long Tubes to the test again in the World Challenge series this week in Sebring Fl. Keep an eye on who has what headers and how well they do . http://leaderboard.vfx.com/SCCA/GT/LiveTiming_800.asp
Well Lou finished in 13th place at Sebring . The Caddilac CTS-V finished 1st and 2nd , I wonder who's headers they used ? Maybe Kooks ?
