To be honest, ran it in the Summer of 2015 a few times at track and Woodward and drove it around town in Detroit and back here in New York a good amount of times in hot steamy weather and so far so good.

I only drove it last Summer 2016 a few times around the streets (one trip was an hour or so out to Long Island in traffic) because I've been busy with work and could not put in the amount of usual miles that I would apply to such a car.
I go under every so often and it looks like the day I installed it.

A few things to consider.
My system is of course from the collectors back where the heat has already come down a few hundred degrees from the primaries, but it was the aluminum mufflers that cut weight the most. No vibrations is the key and using 6061 grade with good penetrable tig welded joints.
The tubes can be had at any good well stocked and knowledgeable speed shop. S&K Speed out here on Long Island has every size tube of aluminum available in stock and it should be common in other outlets being that most Turbo applications keep up their demand.

I also ran a thin wall 321 military grade stainless system along with stock Dynomax Ultra-Flow muffs for a good amount of years and cut off a good sizable amount of weight there.
I forgets the gauge wall though, but they were wafer thin and I got them from Burns Stainless out in Costa Mesa, Ca.

The Aluminum system of course was the lightest and the muffs were done by a cat in Canada by the name of Chris McQuay at Unobtainable welding who made them to my exact Ultra-flow $pecs for me.

I'll look over my notes and post the weight differences compared to stock steel exhaust.
Here's a mock up of the system before the muffs.

Here's the Muffs at Unobtainable welding during construction. I only wished I had the time at the time to make 'em myself, but works calls louder sometimes and Chris is a master craftsman untouched. He does many custom stainless and aluminum exhaust systems for a variety of customers.

Thanks for the response. Mine sees quite a bit of mileage...~4k last year.

I think I will toy around making my own aluminum muffs, but depending on how miserably that fails I may just go with the thinwall SS.

The mileage is not so much the case for reserve, it is the amount of vibration that the systems incurs during usage. Clamp it down good and snug and make good welds and it should be fine. I plan to see some more mileage and running this season if all goes to plan.
You also can not lose with an SS system. It is also light compared to steel tubing. The wafer thin SS tubes makes for more of a ratty treble sound where as the aluminum brings more of a bass and humbler sound.
Will give you weights later today. Got caught up talking up a shop storm with Hemi-itis tonight about his project.

My only concern is heat building up on longer jaunts.

Right now I have a full to the bumper 3" H-pipe system from TTI with 2 chamber flowmasters...I should be able to drop some weight no matter what I do.

Found your weights:




The aluminum system I saw you estimated 20 lbs

Correct.
Thank you.
It's like excavation of fossil answers on this thread with all its length. LOL
Concerned about heat built up on long joints?

I hosted a Jenny Craig weight loss meeting the other night.Some of the usual suspects showed up as well as a few unusual

After the seminar we had some pizza and hung out.Greg brough a precision scale made in Tiwan.We weighed the dual filter set up with steel braided lines,starter and the Accumulator.Any guesses at to the weight??

Back to the headlight topic...

A few years ago I swapped to a plastic H4 conversion headlight I picked up for $35/pair off amazon.

I have since swapped to LED's for the low current draw and awesome light output, but was digging in the basement and came across the old ones, so I threw one on my scale.

8 oz with the bulb and rubber boot

https://www.amazon.com/gp/product/B001UG9K04/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

looks like they went up in price

I am going to guess that the starter is one of the 8 1/2 LB units?
When you post the actual weight please list the part number so I can add it to my list of starters and actual weights.
Still looking for that 7LB unicorn!

OUTLAWD, Frank Romano told me at PRI, he installed all aluminum exhaust on his '55 Chevy for Drag Week. I'm sure he has been putting plenty of miles on the car to test it.

Look at the scale,,,it's 9 to 10 lbs.Not the unicorn!

I see the scale reading now. WOW almost 10 LBS!
If you have it handy it looks like the bar code label has a part number on it?
Thanks! MJ

If you can see it.It's over 10 years in the car.

I weighed my Powermaster starter, and it was 10lbs. They work much better then the Denso units.

That is a Mopar Performance starter part number P4510049.
I will add that to my list.
Thanks! MJ

Anything could have been a Unicorn or a Walrus on that scale. Scale kept changing its mind as far as number readings even when nothing was sitting on it. LOL.
Pardon me for snapping on your scale RMCHGR. "Scalewars"LOL.

I did not have a chance to stop by my studio and pick up the old school mechanical unit, but I will bring it next time and compare.

This headlight thing is now the new Gold nugget to seek.

Thank you FMJ I enjoy the Jenny Craig seminars
And a white or yellow crayon,,,,,,,,,

This is a Mancini MRE 644 proform offset starter at 8.5 lbs.

Oh Sheeet. Never mind that starter, what's up with that super Kool scale????

This is truly looking out to be a scale wars type of thread started by no other than RMCHGR himself.

Mine is made in Mississippi and with good craftsmanship.
Come on guys, break out your best scales and show 'em on the glass.
I've got one in reserve for the last close to chest card move. LOL.
