I'm getting ready to pull the trigger on a set of LT headers. I've pretty much narrowed my choices down to the LG Streets or the Dnyatech Supermaxx's.

The LG's are about $1300 including the cats.
The Supermaxx's are $1500 including the cats.

I'm kinda leaning towards the Supermaxx's because the headers are flanged and should seal with the X-pipe better than the LGs.

Anyone have either system and is willing to share input?

 

Why not try the American racing headers??
I know it doesn't answer the question you asked, but I have them on mine and really love them, just wanted to give you one more to choose from!
There is a real difference in power and they sound unbelievable!! Vette doctors swear by them, ECS loves them as well as A&A!!!

 

Listen to your instinct. I have the Dynatech Supermaxx They look great and fit perfect.

 

The difference is Hp is minimal between the different brands. If you are going to do the install, look for ones that are easier to install. If you are going to have a shop do the install, go with what YOU think are the best ones. Kinda like beauty, its all in the eyes of the beholder.

 

My vette is ready!! I will be back in a few minutes with a vid clip on a closed course!!

 

The decsion is easy VetteDoctors/AmericanRacing Headers all the way.
There is no Better header.

 

I'm trying to decide myself between ARH and LG Streets but was leaning towards the LG's. Here's a related thread by forum member Willfulone who had his LG Streets installed at Carlisle and loves them.

Here is what American racing headers do to your car!! Don't worry guys, this is an empty closed road as you can see!!
SMOKE: The oil is from the differential, no worries here, I filled it a few hours ago, the smoke is the oil drops getting burned by the B&B Bullet exhaust!
GO with ARH!!! 150+ mph passes!!!

 

Sweet Vid!!! Love the sound those make

 

Thanks,
I paid $1550 shipped to NY from A&A Corvette! Andy rocks, give him a call. I just need to send him my PCM to upgrade the tune for the headers! But even without the tune, the car feels a little faster and sounds like a race car (not louder when cruising) but it screams at WOT! I am in love I am telling you! The quality is awesome too!
Good luck with wathever you choose to do, LT's rock!

 

Just my .02

Any header system (I have QTP`s) with a slip-joint/clamp set-up tend to be prone to leaks at the slip joint and are harder to pull apart should you need to.
If I were to buy a set now I would probably go with the American Racing for this reason.

Good luck with your decision.

Does anyone know what the difference is in primary tube length between the Dynatech and AR?

 

For get the slip fits go with VetteDoctors/ AmericanRacing Headers
There is no better header

 

I have the Dynatechs did the install by myself in my garage without a lift. Only took 1/2 day very easy install. My car dynoed 330rwhp with just the headers and Halltech intake. I am sure you would be happy with whatever you go with

 

Might as well do it right and get the LG's. You won't find a better product, or better customer service.

 

I too was at Carlisle and stopped by the LG trailer. Spoke to a LG rep named Luis. He was very helpful in answering all my questions. I plan on getting my headers ceramic coated and Luis said no problem. LG will send them out and get them coated prior to shipping if I want. Cost about $300. I mentioned I might have a guy tune the car using a wide band O2 and he said LG would even weld in an extra bung for the tuning sensor prior to coating. I was very impressed with their setup on display and their knowledge. Lou was also there and while I did not get a chance to meet him, I observed him spending a lot of time with his customers. Do not think you can go wrong with these headers.

I am also considering the ARHs from Vette Doctors. One thing I thought ws interesting about these is that they seem to have a different X-Pipe configuration than I see used with most other headers. Looks like the X comes in right after the collectors on the headers vs the others that have the X farther back stream. Maybe this is just for packaging. None the less, they look impressive. Good luck with it.

 

american racing here.

from what i have read, the x pipe design in the AR headers are superior than the others due to it's location in the exhaust stream.









was a b|tch to get the passenger side on...oh wait you already know that, huh?

 

For what it's worth I just bought a set of LG Streets and the clamps are a joke. Was told on the phone that the clamps were redesigned or taken care of and I received the dreaded clamps. Not a good design. I will be taking these off and welding the pipes.

 

I have American Racing LT headers as well, installed by ECS. One thing to consider is that these headers fit very well up under the car, where as I've heard, the LG headers hang down more causing opportunities for damage from less ground clearance.
