Hi sorry to be a bit dumb. i've just been through the 6 pages of this post... very interesting!

Question......Adrian mentions "decat down pipes and DCI". I assume the down pipes are the same as what we call in WRX terms dump pipes? Is this puely a stock dump pipe with the cat removed and still connected to a stock exhaust, or after market dumb with std exhaust? Secondly what's a DCI?

Thanks
