Mike amd I have the turbo back system from CPE and its single exhaust and you heard how mean its sounds. Get their exhaust its worth the money.(first)Koenig said:I always thought duals were supposed to be louder than singles.... never knew that, thanks man.
LoL. (outie)Koenig said:I didn't know mike had it....... I know you and knowledge have it......and it does sound mean. So yeah I just need to save $1200 aside from all my bills, lol

I would be seriously interested in a dual exhaust version of your catback, in 409 SS. I would love the 304 SS but I pretty much broke the bank buying the car. Still waiting for my new job to start.
And not to go off topic, but I figured that you check this post more than the others, but did you have any success fitting the Speed3 muffler to the Speed6 cat back? If so, any sound files?

Afroman said:Just to state an opinion between 304 and 409 SS.
CPE is correct that 304 is more expensive - this alloy of SS has approximately 8.0-10.0 wt% Nickel and 17.0 to 19.0 wt% Chromium
where 409 SS has no nickel and 11.5 to 13.0 wt% Nickel.
Alloying elements such as Nickel and Chrome are EXPENSIVE!
However I dont see any major problems using 409 SS. In my book from ASM International it states that 409 SS is primarily used for automitive exhaust systems. So CPE Is using this grade of SS for its intended purposes.
For corrosion resistance you need to have about 10.5 wt% or higher chromium content. The 409 SS has that so it will act like a stainless steel should. It will not perform like 304, but it may be worth using.
The 304 is a superior alloy with a superior price tag. The higher chrome will allow for better corrosion resistance and the added Nickel allows for better corrosion resistance in the welded areas of the exhuast.
Here is a page http://www.borla.com/about/ that also has some good data comparing the two steels.
