Quick Question

Is it safe to run a uppipe, downpipe and exhaust without using the cobb accessport stage 2? Will it run like crap without it and will it set off engine lights? Could you run stage 2 with just an exhaust and downpipe? Thanks

It won't run like crap unless you think quicker spool, more HP and more TQ is running like crap. The stage 2 Map is for a cat less car, if you do not replace your stock up pipe you cannot run it. You risk sending the pre turbo cat through the turbo. Do the up and down at the same time though, it is not worth going through it all twice.

You don't 'have to' run engine management with those upgrades but you can throw a CEL because of Hotter Exhaust temps on the EGT in the up-pipe and then the rear O2 usually throws a light...EM is always highly recommended to get all the bang for your buck and when you are choosing EM make sure you do a lot of research to find which set-up will best meet your needs

Stage 2 does not require a catless setup for the uppipe, you can run stage 2 with the stock upppipe but it is not recommended due to the pre turbo cat as mentioned here. There have been some issues reported with the 04/05 years running the TBE and no EM because of the open/closed fuel loops.

'05, probably best off to run some sort of EM. I run a Cobb AP that I'm very happy with.
