O.k. here are some pics of the beginning of the install of the KS 1090 in the Jtec Extra. It actually fits quite well and will only take a little bit of patch work. One question, how critical is it to have the mount on the seem of the pipe? You can see mine if mounted on the former is behind the seem. I really like the mount were it is since it re-connects the former. Also, I will need to come up with some sort of mount on the front. |

Nice setup--
Having used a number of KS pipes - they are fragile - -just a fact -
You will likely dent the pipe with your setup.
also you MUST restrain the pipe from slipping aft -the internal pressure wants to blow it off and in many cases -it will
clamp at the front and every joint!!and if possible put a restraining device in place. A good one is a very rough section where the pipe attaches to the header -then use a very strong spring clamp - these will bite hard into the teflon . I also prefer to use a stop at the end of the pipe - a small wood/silicone setup (like you used to support the pipe) but simply designed to hold it from moving aft Up front make a silicone rubber padded support that applies NO pressure up down or sideways on the header/pipe joint - this is important. You can loosen or break the header or couplers.
Very high exhaust temps can gradually cause the pipe to slip aft - and it will slip off at the worst possible moment . so check this part out thoroughly.
to recap - the engine and pipe should never be forced into a position -the header can be tweaked to get exact alignment --then-- lock the pipe into that position. The couplers will do the rest if the header is a flex center type.
My 80 ZDZ's are similar setups and I made a number of mistakes before I found out that you have to get alignments perfect ---- then--- lock the pipe in position.
It'sall worth doint -once you match the prop load to your pipe setup - that takes a little listening and needle adjusting - just don't be afraid to experiment a bit . and DO NOT get it into mind that some particular prop is "best" --just use one which matches your pipe setup.
