Do you want a new catless downpipes or an O2 extension?

As far as extensions go, just get a park plug anti fouler. $7 Autozone.

An O2 extension that will fit a F-series Mini. I found one that will fit a R-series & they say it won't fit F-series. I wanna cap it off & let it hang, I wonder if R & F will interchange or different threads ?

going to Mini to look at both R & F O2 sensors, I think they're the same. wanna cap it off & leave probe exposed to air. Florida-Free, wire-tie it out of the way.if it pops in your head let me know. they say if you extend it, even with cat.less DP, it won't stop it from setting it off because it's cat.less. that's what happens when you buy a used car, somebody else's headaches. .my B46M = N12, N14, N16, N18 ? I'm 403FORBIDDEN At ECS website, is that website problem ? or me ? wonder if I could find an american cap to just Jam in there. metric 18mm ? would be nice to know. gonna be hard to find M18 cap !

here's the deal, IF & WHEN my O2 sesor goes bad due to cat.less DP - I'll leave sensor in place, cut tube, unplug plug, plug in New Plug, & zip-tie probe up & away where I can see somewhere near firewall. should I ever need a sensor in Cat.less DP, I'll have it right there to re-install. GOZINYA !

Love it ! can't wait to install. when you Hot-Tune your F-56 past JCW Tune Kit & go water/methanol injection +, you need a SS exhaust. having a Magnaflow SS 3" exhaust, I was lacking SS downpipe. NOMO ! BAD TO THE BONE

Definitely go with MarioKarts "jewelry"!!

Do not remove the upstreamt O2 sensor, that one is critical. The downstream (past cat) is only there to tell the ECU how to respond to the cat's performance.

MarioKart is the Ace-In-The-Hole ! not going to cap off ANYTHING. that's not a cat, just a flex-connection. the downstream O2 sensor bung is recessed BIG TIME. try to buy a downpipe, then try to buy a SS downpipe. I gaurandamntee you, you'll get one from MarioKart.
