I just pulled the code and got Catalyst Efficiency System Below Threshold. Everything is stock on the car.
New Cat????

Whats your guys opinions???????????????????

 

New cat, and possibly secondary O2 sensor.

 

So i can go with an aftermarket cat now...
Ive been looking into new catback exhaust so this came at basically the right time.
New cat...new exhaust.yay

 

throw on a new secondary o2 while your down there just to be safe, so your not doin things twice

 

Do most USDM cats bolt right up to T1R 63...
and any preference on new cat

 

Ok so how bout...t1r 63s full cat back exhaust with SMSP high flow cat...will that work out

it will work, but alot of people have problems throwing that code even with a new aftermarket cat

 

Are the T1R exhaust still available? I thought they were discontinued?

 

Not sure if Carsound is still making cats but they were notorious for a premature death. Search for a good name brand other than them.
