SS exhaust system?
Anyone have any experience with this system?
http://www.ecklers.com/product.asp?p...dept%5Fid=1267
I noticed it is less than half the price of SS systems I've found elsewhere.
Also, anyone know how it compares to the aluminized system Corvette Central sells for almost the same price?
Thanks!

So, the SS system will end up costing more with mufflers, but maybe it's worth it for SS? Anyone have any opinions?

The add reads:
1/2 of the system pictured.
I think you are only getting half of the pipes, that's why it is priced so low.
I am going with the aluminized system from CC next spring.
Good luck,
Dino

Thanks Dino.I guess I'll go with the CC 2.5" set with MagnaFlows hooked up to the ceramic-coated Hooker headers I just ordered. The body is still off right now, so install should be pretty easy.

Just received my 2 1/2" aluminized system from Willcox today, no need for SS here in W Washington. Looks to be good quality. Included "performance" mufflers (not welded), and clamps. About $270.. Install tonite after new fuel tank goes in. Might be running by tomorrow!!!!!

If you can wait, CC offers discounted shipping on exhaust systems. I don't think it is going on right now, but will probably resume in the next few months. I am going to jump on the sale when it happens. I won't be driving mine until spring anyways.
Good luck,

Stainless expansion problems????
G'day,
I read an article in a recent Covette publication where they said that the problem with stainless is that it expands and contracts (with engine running/not running) much more than aluminised mild steel and that if you fit a stainless exhaust, you should be prepared to do a lot more adjusting hangers, brackets, etc.
Anyone have any knowledge on this???

I just ordered and received most of my dual kit from CC. I say most because their not sure where my intermediate pipes are right now. Since this is a kit, which implies most average folks can install it, it sure would be nice if they made them to bolt up to headers. I got my headers on this past weekend and plan to put the pipes on tomorrow. I ordered the alum steel from these guys because I really liked their tech guys who answered my questions.

I also read that on CorvetteCentral's site:

I guess modern cars can get away with it because they use flex couplings? I have no idea otherwise...

As usual, one has to sift thru the marketing hype.
So that is only a difference of .1573 in. or a little over 1/8 inch.
Here is a link for what they say on their lifetime waranty stainless.
http://www.stainlessworks.net/cart/faq.php
Here is some more info:
This can be found here with other links
http://www.burnsstainless.com/TechAr...s_article.html
and a more general link
http://www.burnsstainless.com/TechAr...harticles.html
Interesting info on the above sites. Take a look at the header on the Inconel link
As I said it's hard to sift thru all the claims, but I suspect that profit margin and sales has more to do with promoting a product to a general public with a budget in mind, thus the info may be swayed that way.
Aluminized=more sales, more profit
Stainless=less sales, smaller market, much higher price
Does stainless expand a lot more than aluminized steel. I have heard that a stainless system will grow 1 ½” in length when it gets hot. Is this true?
In a word, NO! If stainless systems expanded as much as some olds wives tales would lead you to believe, then how would so many OEMs use it and not have problems? The key is to look at a property of the material called the coefficient of thermal expansion (COTE-Geek terms for how much the material will grow when it gets hot). For mild steel the COTE is:...Looking at an exhaust system that is 84 inches long, and whose temperature will change 600 degrees F, on average, for mild steel:
change in length=.3157 inch.
For stainless: =.473 inch

http://www.stainlessworks.net/cart/faq.php
Here is some more info:
Typical 1010 carbon (mild) steel conducts 219% more heat per foot than do the types of stainless steel we use in header fabrication. By contrast, quite a bit more heat stays inside the stainless header tubes and does not get passed into the surrounding air. By not allowing the contraction of the cooling gases as they flow down the tubes, more exhaust velocity is retained which promotes better scavenging at the collector. This retention of velocity increases the overall header efficiency.

That's a very low price for a SS system. You can't go wrong if you buy it even if it doesn't hold up your out less then $300. Go for it and let us know if its a good deal. When I put my 2.5 aluminumize duals the tech rep talked me out of the SS which was three time the amount. He said it really wasn't worth that much more. Maybe the price is coming down.

I installed an Allen's SS exhaust system on my 1973 in 1991... It was not cheap, but has been halfway around the world and back and it still looks terrific. (Many of the vendors carry the Allen's system.)
I've never experienced any problems with the system related to expansion/contraction, or any other reason for that matter. Buy it once and forget about it in my opinion. I did remove it about 4 years ago to do a frame-off on this car and reinstalled it as before. Oh, and it sounds very nice, authoritative, but not loud and certainly not tinny...

Stainless does not sounds tinny..the only drawback is weight, expansion is really not an issue. Nothing more beautiful than a hand made tig welded stainless exhaust (from weld els and straight sections) IMO.

I know I guy who had full stainless exhaust on his stock 340 horse 62 Vette and removed it to sell this past Carlisle. His did sound very tinny, which was the sole reason for ditching it, it just didnt' sound right. I think he went with aluminized pipe, but whatever he put on it, it sounds like it's supposed to now.
