Samurai 20V Posted April 4, 2011 Share Posted April 4, 2011 Wassup guys.. I have a stainless steel 1st decat (75mm) and a Kakimoto Cat back also stainless steel (85mm). I was planning to buy the HKS 2nd decat (75mm) which is mild steel to keep the diameter and cos it was slightly cheaper. Is ok to run stainless into mild steel and then back to stainless? The other option is the Kakimoto 2nd decat which is stainless steel and 80mm. It is slightly more expensive, but wont break the bank... EIther way I need a RR (which I have) so just have to confirm the material spec. Thanks. Quote Link to comment Share on other sites More sharing options...
Wez Posted April 4, 2011 Share Posted April 4, 2011 Its fine to use a mixture of different materials from turbo back Quote Link to comment Share on other sites More sharing options...
