Scott Posted October 23, 2007 Share Posted October 23, 2007 I completely forgot to ask this. As far as i can tell the engine in my Supra doesn't have an aftermarket dump valve yet i get a small woosh when i change gear after being on boost. Is this normal? On my MR2 i couldn't hear the recirc dump valve at all. Also, what are the advantages of replacing both CAT's? I am definitely going to be replacing one of them with a De-Cat but is there any point in getting rid of both? Thanks Scott =op Quote Link to comment Share on other sites More sharing options...
