Does anyone make a Stainless steel 4 inch down pipe, if not, what is the next best thing. I like the cooleeze megamouth, but apparently it is not made in a 4 inch version. I am skeptical of ceramic coated aluminum holding up to 2000 degrees as advertised. I do not believe the aluminum can take it.
Anyway, I am looking for a Stainless 4 inch down pipe. Thanks

 

I don't know of any downpipes made of aluminum. They are aluminized, which is simply a coating. I think a ceramic coated steel pipe would hold up fine. My .02 anyways.

 

Well if I read the description right on the cooleeze big mouth, it was ceramic coated almuinum. Tell me I am wrong.

 

i bought a complete 4" 409ss turbo back from summit $400 shipped.i think the dp was $89 alone

 

I read both the description in the DTR store and on the Cooleeze site, and neither mentioned it being aluminum, only that it comes with a 2000 degree ceramic coating. I dunno

Even if it was aluminum, if it's ceramic coated inside and out, the actuall metal will never see those kind of temps. It will get hot no doubt, but not nearly as bad as one might think.

 

Here is where I got the aluminum from:

It is aluminized with a Ceramic coating, A really beautiful product in person. If I did not have an exhaust brake on my turbo elbow, I would be running one of these myself


Is Aluminized the same as aluminum?

2500Superram, is that for like a 40 or the non stock turbos with 4 inch outlets? I am getting confused. They say this Megamouth is available in 4 inch, but I am thinking from the description, it is not 4 inches from the Turbo Back. Please correct me if I am wrong. I like the Stainless one Superram mentioned, & I bet I don't have to wait 2 months for it either.

 

aluminized is not the same. an aluminized part is coated with aluminum for rust protection. it will how ever rust eventually as the aluminum is acting as a "sacrificial anode", extending the life of the steel that lies beneath
