Order a set of these off Canuck Amazon and you'll be able to drive as long as you want before tuning it. These aren't available in the States,as you guys have some really whacked rules down south,but they work.

ld one, why would i need these adapters if the long tubes come with 02 sensor extendor harness and i plan on keeping the cats

I also have tunning scheduled with FRP tuning and Flying Ryan not sure if there is a need for the 02 sensor extendors at that point the tuning should get rid of the check engine light correct?

If you plan on keeping the factory Cats you're good,but if you plan on running a set of so-called hi-flow cats,then these will keep it from turning on an 02 code.Alot of US tuners won't tune out the back 02's anymore,if you're tuner is sticky about tuning them out,these will keep your putor happy.
Everything i own is catless with only 2 of them being tuned,and these keep the putor happy on the untuned ones.
I ran the wifes 1320 Challenger for a year with long tubes and no cats before i got around to tuning it,with no codes,and my 300C with a 5.7 is running the 6.4 manifolds and catless midpipes along with the complete exhaust off a hellcat with no codes,and it's never been tuned,and it's been that way for several years now.
They don't hurt,even if you're tuned,but they work really good on untuned vehicles

tracking all. i guess it would hurt to just put them on anyways. im glad i can see that even after putting long tubes you can take a while to tune your vehicle, i mean im not planning on running the truck un-tunned but maybe a couple of days i was worried that it would run right to get it from the exhaust shop to the house and its a 40 mile haul

It'll run perfectly fine untuned with a set of long tubes,you just won't get all their benefits until you tune it to take advantage of the free'r flowing exhaust.I ran my truck for about 3 months untuned with long tubes and no cats,with a set of those 02 extenders it ran good till i got around to tuning it
