Looking to increase HP for my 97TT but I need to pass New Jersey emissions. Any suggestions?

I'm in Calif. and I got the Random Tech HiFlow cat/extension pipe.

I expect that this cat will pass Calif smog but I'm not sure yet.

I'd consult with the RT guys.

One comment regarding the RT cat, should you go that route:
Their cat has a flex joint which, in my opinion, doesn't restrain enough the ex sys and also causes it to hang too low. In my case (TRD ex) I elected to custom weld on a second support arm at mid section (ex).

Another Supra owner contacted me recently to get some advice on restraining/lifting his PE ex (for the same reason - RT cat). He ended up installing a custom mount.


Good luck,

Jay :cool:
