Exhaust help ASAP please =(
I am posting this in the exhaust forum because I firmly believe it is the exhaust doing this.
My setup:
revised VQ35DE (one year old replaced under warranty)
Nismo S-Tune catback
Kinetix V+ plenum
JWT SRI.
Ever since (lol I know dealerships hate hearing those two words) Nissan replaced my engine my car has been smelling funny under load ie. going up a hill. It has that rotting egg smell. I know this is the cats doing their thing but here is the weird part: When I had to replace my kinitex V+ plenum I had to put my stock intake on. Smell went away.
So when I got my new Kinetix put back on, the smell came back. But that wasn't the ONLY thing. And this is why I'm posting this.
An odd exhaust sound has started. I got it checked TWICE for leaks and its solid. No holes, no leaks. It sounds like a freaking Honda Civic, all rasping under WOT and its louder in the cabin. What could this be? No codes, no CEL, but the sulphur smell is back under load and WOT.
I want to post a video showing what this sounds like. Could this be a broken baffle or catalytic converter going, or a resonator blown, etc. I don't know. It sounds HORRIBLE.
Its like someone stole my Nismo exhaust and replaced it with an Ebay muffler.
PS My exhaust IS old, its one of the first Nismo exhausts ever built (installed on an early 03 before I bought it)
Thank you guys!
HAPPY NEW YEARS MISS EVERYONE!!!

03 will probably not throw a CEL for bad cats. You can run test pipes on an 03 without nonfoulers and not throw a code.
