Nissan 370Z Forum - View Single Post - Moving Cats downs stream, o2 extension harness

Looks like those worked. I purchased a spare motordyne Y section and replaced the flex sections with a clamp on high flow cat cells. Idea is that if I move the cats more down stream, they will stop blowing into pieces. If they do, then easy replacement. I put on resonated Fast Intention TP's with Hemholtz resonators like the Motordyne ART's. I am hoping that I can bring down IAT's in WOT (because of back pressure on stock cats) but at the same time keep the exhaust drone/rasp/loudness down so I don't go deaf.

Harness I created was 24".
