Downpipe w/JB4

[larrymz3]

HOLY CRAP! I just got back from getting my Titan downpipe and Fabspeed 02 extender installed. With the JB4 on map 3 and the downpipe, the car literally feels like a completely different vehicle.

The sound and acceleration are incredible! The JB4 w/stock downpipe was awesome, but, the addition of the downpipe seems to have taken things to a whole new level!

With this combination, I honestly don't see the need for a flash tune right now.

Good to hear! I'm about to get mine but don't want any CELs. Were you able to avoid any codes?

I'm on JB4 now with map 3 on stock downpipe and it feels amazing. Can't wait until I get my new downpipe installed.

You will love it. The difference with the new downpipe and JB4 is night and day.

Just got my downpipe put in and running on JB4 . WOW! The exhaust is so loud and it really opened it up! Saved 3lbs from stock too. The O2 spacer I purchased from euromotive performance for $80 worked so far. No CEL.

Is this the downpipe for the supra or b58?

Did you happen to look at the 02 extender before install.
Is this the bigdaddiesgarage cat o2 extender?

Does the JB4 not have an option to cancel out the CEL without an O2 spacer? Or is that only on flash tunes....?

Sport CAT or No CAT?

It used to be able to automatically clear codes everytime you started the car... they took the feature out citing "emissions laws." You can still manually clear the code in JB4 app, but, autoclear is gone.

Personally, I think that's dumb - there should be an exemption for folks who live in states with no emissions check.... or for those who use for race purposes only.

Yes there is an option to clear the code but I haven't had to. No codes so far.
