will all the subi hating these days, i was thinking about rollin with a stock exhaust, but keepin the UP and DP on to avoid attracting any cops. i know there is a restriction in exhaust flow, but is anyone doing this without affecting the drivability?

I run a stock muffler, but with all 3 cats removed and an ecutek re-flash and it runs fine. On gruppe-s dyno I make 200whp. It's nice and quiet.

Up/dp with stock cbe will work. I have up/dp + Prodrive with stock intermediate pipe on without a problem or hassle.

up and dp. it pulls harder. lol but u need to get ecutek.. or else it'll over boost and blow up ur engine or turbo... (I NEED an ECUtek BADLy before its too late... where can i get a cheap one?)

cool. i have an accessport, so i could always just get a tune. does the ecutek have a reflash specifically for a up and dp upgrade with a stock cbe?

oh... and how does it sound with just a up and dp on without an exhuast? its a nice rumble with the up, dp, greddy evo2 setup. im wondering how quiet it would be and if the low rumble will go away completely.
