Not sure about NissanTracker but I'm running them to keep the exhaust smell down a little bit

Yes and No. This is a HPDE/street car so I want to be able to pass emissions, but I don't mind using o2 extenders. They are mainly to keep the smell and sound down and to relax the inner tree hugger inside of me. ;-)

I have been running the GESI hi-flow cats in my down pipes for years now. No cel and will pass CT emission with ease.

They are rated for 600hp ea. & 1400deg F - EGTs

Those GESI's are great. A little expensive but the best. I went with Mil Spec. A little cheaper

Some high $$ rolling right there. Haha, I went with Magnaflow 200 cels.

If I had a TT kit, I'd probably invest the money for GESI's/Mil Spec for higher horsepower. The Magnaflow's I got are geared towards V8 exhaust setups and should handle. I'm only at 475 on an v3 SCI 12psi. May upgrade to a V3 SI blower for that extra 100 CFM and see if I can squeeze past 500.

Part of me wants to have some high flow cats welded in to part of my exhaust too. It’s getting harder and harder to get cars without emissions equipment inspected. A Firestone wouldn’t inspect my G35 because it has an aftermarket magnaflow muffler on it. That’s the only mod to the engine/exhaust….

Plus, I have a bit of that tree hugger inside of me too that feels a little bad for having a street car without cats.
