Default Headers?

This is kind of a three part question, I guess.

(1) Has anyone been using the Dynatech Supermaxx headers? Curious to know how they stack up against the other brands available.

(2) Along the same lines, which brand of headers appears to give the most bang, all other variables being equal? Prices between the ones I have looked at are so close, relatively speaking, that I wouldn't consider a more expensive one as a negative factor.

(3) Any ones in particular that are in the "stay away from" category?

What I am looking for is a nearly complete system up to the stock Z06 titanium mufflers. I can't see replacing the mufflers unless there is one hell of an overriding reason to do so. I'm not looking for more noise, but instead want more power. But if more power REQUIRES more noise, then so be it, within reason. I'm not willing to spend the money for a new muffler system just to gain 10 horsepower.

Thanks.

We just finished installing a set of LG Streets on a 98 coupe and they worked just fine. Comes with everything to bolt up from the headers to the mufflers and cost is ok. LG Pros are a little more and that is what most people like

I've got the LG Streets on my car and couldnt love them more. They look and preform wonderfully. They use the same tried and true design of the LG Pro Long Tubes, the primaries are exactly the same. Only difference is in the collector and x-pipe. And of course the Streets are polished stainless.

Vette Doctors use a slightly shorter primary. Might lose a little low end torque over any of the others.

I have them on my Z06. Fit and finish is as goos as any other brand. Install is straight forward and easy(instructions are actually pretty damn good). Just make sure to put the bolts back in the starter BEFORE you snug up the passenger side header. Sound is better than stock and power gains for me before and after the install netted 37rwhp. For the money, I feel it is the best system out there. An extra $500 for maybe 2 or 3 hp/ft.lb. of tq. from LG wasn't worth it at all.

My LG Streets were only $1200 and got me over 50rwtq at 2500rpm

And they're polished.

Dyno sheet is in my sig.

LG Pros here and I love them. I just hope that I never have to change the starter.

These headers are within a few horsepower of each other. I just kept looking for a good deal on whatever used set came up. In my case, I got a deal on a Supermaxx setup that I am happy with. I did heads and cam at the same time, so I don't know what performance improvement the headers alone provided.

Yeah, there appear to be a lot of options out there. I notice that Kooks has 1 3/4 primaries and 1 7/8. Is there really any difference from that additional 1/8th inch diameter? Any other issues that would arise from the 1 7/8 inch models that I should keep in mind?

The Breathless Performance two piece units look interesting because of the issues with later under engine maintenance that would keep you from have to pull the headers completely off of the heads to get to some things. Yeah, clutches and starters WILL die, and I need to keep this in mind.

Whatever happened to Hooker headers? That's what I had installed on my GTO back in the 70s. Are they still kicking? Of course, the selection back then was nothing at all like it is now.

Oh yeah, when you all paid someone else to put on the heads, hi flow-through cats and X-pipe, what did it generally run you in cost? I don't have a lift available, and and not at all inclined to do this kind of work myself any longer.

Thanks.

If you still have a 346, don't go higher than 1 3/4". You will lose velocity and power. The 1 7/8" are for higher displacment motors.

Very impressive. I wish I had known that a few months ago. But I am happy with the SuperMaxx. Whole system(hi-flow cats & X-pipe) cost me $1178.

They're streets, somebody else made my sig and i haven't the photoshop skills to change it. If you want to get technical they are the "Pro Street" series


And LG is running free shipping on them till the end of the month.

You know, I'm looking a side by side photos of both the LG Motorsport headers and the Dynatech Supermaxx ones and there really doesn't appear to be that much difference in the design.

So what is the difference between the LG Pros that gets 5 more horsepower over the LG Streets?

Heck, maybe this is all just a study of "inconsequential increments".

Oh, and thanks for the link.

LG made them first. The LG Pros have a merge collector, which is supposed to add a few HP and TQ. They are also 3" collectors and pipes, through the X-pipe and all the way back to the cat-back. LG Streets (and most other brands) don't have the merge collector and are 2 1/2" from collector to cat-back. IIRC, the Street x-pipe is also stamped, instead of handmade. Do a search for LG headers and you will find many posts where Lou (Mr. LG) elaborates on the differences. On a basically stock engine, the difference is small. Start modding, and it gets larger.

Hmm, so for a stock LS6 the 1 3/4" primaries are better then the 1 7/8" ones? What about the difference between the 2.5" and 3.0" collectors and pipes? Same thing apply there? Do the 3" inch pipes give the exhaust a deeper rumble to it?

What about ground clearance on the LG Motorsports? I take it some headers have better clearance then others?

I dont know about the clearence on the pros but on my Streets clearence is absolutely not a problem. Also, The collector on the streets is 3" It's in the first section of pipe after the collecter that the step down from 3" to 2 1/2" is made.

The X-pipe on the Pros is better though. With my screets i still get some pop like with the origonal H-pipe. The Pros dont have near as much pop. And the bigger pipe means deeper sound. I love my LG Streets but if i had big mod plans in mind i would go with the Pros. I'm not going to do anything more than a cam and maybe some ported stock heads so the Streets suit me just fine.
