Just to confirm - were you on a tune or piggyback?No CEL. The catless however will throw a CEL but can always be fixed with a tune
Or
No CEL on stock tune??

Tuned with Bootmod3 and no CEL the moment the downpipe was installedJust to confirm - were you on a tune or piggyback?

Am I missing any? Maybe this could go at the top of this post, and then we can add to it. Moderator?
Also, just to make sure. O2 spacer, O2 simulator, and cat simulator are all the same thing, right?
Have you seen dynos showing power increase without tune? Usually just changing the DP won’t affect power output since the engines configuration wasn’t adjusted (which is where a tune comes in)You should see about 30-35whp with downpipe only.

Actually the 30-35whp was without a tune. I did dyno pulls after every change and that was what it picked up. I was getting it tuned the next day and just ran it on the dyno to see the gains before the tune. I don't recommend running a catless downpipe without a tune but I did want to see what the difference was to document it.Have you seen dynos showing power increase without tune?

That all depends on what you mean by some power. 35 whp is not some power to me, thats a lot of power from only a downpipe without any ECU tune.Going from a stock setup to a catless setup on a turbo car. Downpipes almost always gain some power with just the swap. its physics.
In order for a mod to void any warranty mod, the mod has to be responsible for the damage. Downpipe do not cause any extra stress on the car, if anything they reduce back pressure on your turboStupid question time. Will a downpipe without a tune void the warranty on the engine?
