I'm now on my 2nd year with Topgunz A-A upgrade after 15+ sessions with Seb and have not had any issues with Cats. I'm running stock cats with a Motordyne TDX, down sized pulley and Zspeed clutch set up. I love the gains on TopGunz kit and my A/F is more predictable. I went from 338wHP to 450wHP with the new set up. Problem is that my IAT's get high and I see knock and it pulls timing. (probably because the stock cats are a restriction now). HFC's on the Motordyne was very loud. I actually enjoyed the sound with stock cats, but IATs. ART pipes seem to be the go to with the supercharger. Sebastian gave me a tip to move the cats further down if TP's were too loud, So.. thus this the changes. Won't be able to run it until the spring though.... my Nismo's are hibernating Last edited by NissanTracker; 02-26-2022 at 08:44 PM. |
