Anybody have boost creep even with catted dp?
Hey guys,
I have been deciding back and forth whether or not I should install a catless downpipe so I can run Cobb's stage 2 map on my STI. If I install the catless I will have my wastegate ported to prevent boost creep. My other option would be to install a catted downpipe ,probably the helix, and run the map and still most likely not have boost creep since I have the cat.
My question is this: Has anyone experienced boost creep even though they had a helix catted downpipe and if so is it worth it still getting your wastegate ported?

Unless you are running ungodly amounts of power/huge turbo, why bother going catless? It smells bad, runs like crap, and is a ticket, trip to the state ref, and hefty fine waiting to happen. Not worth it for the extra 5 whp (I dynoed my 02 WRX, with the same power setups, with and without a downpipe cat and that was the result).
