Im looking to buy a used HKS downpipe, but im wondering how many different types were made. I need to make sure it will clear ACD on my Evo 9. do they have a 3" made of stainless steel?

 

The SS downpipe for CT9A EVO's using an OEM turbo is 65mm in diameter. So, I guess the answer is no.

Have you checked the HKS USA site? Maybe they have something new listed.

 

it will clear the ACD bar.

 

They actually make two for the stock turbo,one is 65mm,the other 70mm. Both are stainless steel and are designed to work with ACD cars. One has no flex section and the other has a flex section and is sold with the GT Extension kit (read O2 housing and 70mm downpipe) pictured in the link below.
