you get the BRAKE
Sorry but I have never heard of an alumium manifold. Ever thrown a beer can in a fire? Well it melts! The same thing would happen if exhaust right out of the head was going through aluminum. All tubular manifolds are steel. Stay away from ebay brands, and expect to pay $600+ for a quality piece such as full race or peakboost.
lol where have you been for the past decade or longer? goto specialty exhaust shops...you know what they use?? Aluminized piping. every single shop does. its very rare to see a shop bend stainless steel pipes..its not exactly possible to me. Also, all those manifolds (turbo) on ebay, such as the XS power kits...yes, those manifolds are infact, aluminum. I know from experience, ive cracked them many times in the past with cheap setups and when I went to get them re-welded, it took them quite a while to do the re-welds and had to use a TIG.
