So I will be getting a full TBE ( UR Downpipe and TP and Greddy catback) Though i don't think I will have the equipment to put ont he downpipe in a timely manner until later, so I was looking to put the testpipe and catback on for now.

My question is: is it dangerous to have a testpipe with a stock downpipe?

Also: I am currently tuned with a Cobb AP, and if it is safte to do a testpipe/catback with stock downpipe, would that constitute flashing to the stage 2 (TBE+intake) or staying stage 1 (intake) until I put the downpipe on?

I greatly appreciate any help!

 

I had my tp and exhaust on for about 500 miles before I put the dp on, I personally have AMS products. I had no problems running without the dp.

 

How were you tuned for it? (if at all) Pro or cobb AP... or self?

 

No tune as of yet. Been waiting for cobb, but will prob go different route if they dont come out with some maps soon. Car just runs really rich.

 

So do you think tuning for a full TBE will work for just catback and testpipe?

 

cobb's stage 2 map should be perfectly fine but it's always a good idea to log after switching maps

the main requirement in cobbs maps is either removing the cat or getting a high flow unit

 

I'm running with a testpipe+catback with stock downpipe. Cobb ap stage 2 the requirement. No problems here.
