Looking at the miltek catless DP, it seems that Miltek is very adamant that it will only fit a miltek exhaust system. I've never seen a proprietary fitment like that and just assumed it would be a simple v-band to install. The car I just bought has an akropovic catback on it, and before I order the miltek I'm just looking for some assurance that it'll fit. If I need to take the DP to an exhaust shop to have a different flange welded on that's fine, trying to have my ducks in a row before hand though.

 

My understanding is that the Miltek downpipe will connect to the OEM exhaust. If the AK exhaust will bolt up to the OEM downpipe, then it should also bolt up to the Miltek downpipe.

 

+1 it will connect the factory DP if its the USA version. I know the euro cars don't have the same flange and they go to euro cat backs. The USA version DP will not connect to a Euro Version (uk) cat back as its a mismatch on the flange.
