The 02 sensors go right back in their stock location and I still dont have a check engine light 😁

 

So I tried to do some pulls on the 22s but with the extra power from downpipes is making it impossible to get traction on the street from a dig. Here is a video I made with the results:

 

nice!

 

So I took off my 22" wheels and put on my stock wheels to more accurately gauge the increase in power the catless downpipes give.

Check out my new 0-60 time on the street


Here is my new 1/4 Mile on the street

11.8 at 118mph



Here is my new 60 - 130mph



Needless to say the car picked up at least 25 - 30hp with the downpipes and bmc filter

 

Surprised it would be that high without a tune.

 

Any check engine light from the O2 sensor yet? I'm wondering how they gutted the cats with those bends, I'm assuming with some trickery. I was looking around for used stock downpipes and they're quite costly still, I suppose I can go aftermarket for the same price...I figure when and if I need to put the cats back on for whatever reason

 

i sold
mine for $500 shipped them all the way to Alaska

 

so I recently got a check engine light but it was after I installed the piggy back tuner. I have to pull the codes to find out if it's related to being catless or something else related to the piggy back tune.

 

let us know the code, I was CEL free for a while then it threw a down stream 02 sensor code. Waiting to replace it now.

 

I would be surprised it wouldn’t try to lean the engine out with no cats too.
