Sounds like good reasons to me! :cheers:

I weighed my set on a 50lb postal scale I bought for weighing parts:

Stock Manifolds: 12lbs x 2 (all the double walls were cracked and/or gone !!!)
H-Pipe: 44lbs

= 68lbs

Kooks Headers: 10lbs x2
Cats/X-Pipe/Intermediate Pipe: 29lbs

= 49lbs

FWIW, the cats weigh a TON on the Kooks system, so you could reduce that by at least 10 pounds if you were going with the catless system.

Huge Thanks JakeL! :cheers: :cool: :thumbs:

It looks like the list is complete.

Added Stainless Works to the list.

Has anyone weighed the Dynatech Supermaxx? Seems out of synch with the rest of the systems. Original theory was they had a cast collector, but that is not true.

BQuicksilver

I agree, that one does seem a bit off. Maybe some new owner will chime in. I think that weight came from z06vette.com

QTP are 50 lb shipping weight, installed weight may be lower especially because no clamps are used.

BQuicksilver

Thanks, give me the final numbers once they're out of the packaging.

Wow, thanks for this great info. I've been trying to get an estimate of the weight savings I've achieved with my mods and this has really helped. For those of us with Pre-cats, how much do you think each one would weigh?

BQuicksilver

That's tough to know, as I got my numbers from having people simply lay their systems on a scale.

I'm sure someone has a precat laying around that they can weigh.

From my FLP install page:
THE WEIGHT OF THE SYSTEMs:

Weight of QTP's can be found here in this forum thread:

QTP Header Weight

Note that I weighed these on a scale accurate to +/- 1 gram so the weight should be pretty good

Thanks for the added info, unfortunately with the software change I cannot update the original post any longer.

While we all realize that lighter means quicker, could it be that the 13 or so lbs of the Dynatechs means that thicker gauge stainless is used? Maybe the flanges welded to the collector tubes that bolt them up to the heads is thicker? Could this possibly mean less prone to stress cracks or other problems? Maybe this is a question we should pose to Dynatech.

BQuicksilver

I've wondered the same, but I don't think asking Dynatech is the best source, since they'll surely say the extra weight is just extra quality.

I think the best we can do is see if field reports of cracked LGM/QTP/Kooks come back more than Dynatech. Haven't heard of any of these cracking yet. Maybe the Dynatech's have a bit less "ticking" noise transmitted, as is a common complaint with others. Just thoughts.

It could also be that the others just did a better job with weight reduction.

Ron Price

I do know that the four clamps used by Dynatech are quite heavy and weigh something like one pound each. Not sure what the clamps on other systems with cats weigh.

BQuicksilver

All 4 clamps together weight 2.5 lbs, I just weighed them.

My Dynatechs came last week. The shipping weight was 79 lbs. All of the packing material couldn't be more than 7-8 lbs.

BQuicksilver

If there is any number I'm confident of, it's the Dynatech number. I'm sitting next to a set as I type.

I know I am bumping an old thread but I have a relevant contribution.
