re: my post that dose pipes kill performance. I ran a dose pipe for a few days. car lagged like sh*t, overboosted, it sucks in all the hot as f*ck air from the engine bay. sure it sounds cool (for a while) but my car felt too laggy, and probably lost about 10rwkw EDIT: DOSE PIPE being a 90 degree bent pipe coming off the turbo with a pod on the end
