Re: Aluminum Exhaust
I didn't know which to post it in. But I figured the only guys running aluminum exhaust would be turbo guys because of the large piping looking for weight savings.

Re: Aluminum Exhaust
Not sure if this is really on topic for the thread, but it fits with the title:
What have people noticed related to in-car sound level with aluminum exhaust tube compared to steel? I'm thinking I might want to try some this spring, but if it's known to make the car super noisy inside, then I probably won't mess with it.
Thanks in advance!

Re: Aluminum Exhaust
its hard to say. i think if your at the point where you use your car on the street and what not--- where you are concerned about sound, the aluminum exhaust probably isnt worth while at that point.
it seems when you go to a 3.5-4 inch exhaust...its actually louder over all than open downpipe/header. thats when you use a "race muffler" anyways

I'm planning on only running 3", into a pretty good sized oval Magnaflow, so I may give it a try just to find out how well it works. I'm thinking an eBay intercooler pipe kit will give me most of the bends and whatnot that I need, although not much cheaper than Global-Tech, so I'll probably just go that way. Everyone seems happy enough with their mandrel bends and overall quality I guess. . .

Re: Aluminum Exhaust
It won't melt the downpipe unless your tune is really really f'ed. And at that point I think you will have some engine problems too

Re: Aluminum Exhaust
dont use that ebay tubing, its generally thinner than 16g and i have gotten calls about that cracking/blowing holes in it.
i made an aluminum downpipe for a K series car that went 9.3 at over 160....it only lasted 2 pass's before it blasted a hole right through it. the downpipe had to make a really sharp turn directly off the turbo and i think that was the problem. either way, i just stick with stainless downpipes now

Re: Aluminum Exhaust
I guess I'll get my stuff from global-tech, and maybe if I'm lucky welding it will be easier than it was on that eBay tubing too. I hope!
Thanks!
