Original post was for L99

 

We also modify the up-pipes (when we can find the time) to include flex joints and get rid of the stock connection at the turbo. We have a custom fitting made locally that bolts right up and uses no gasket or anything, and has a great fit to any stock collector.
I can't discuss prices in the open forum, but I can say mine are almost 1/2 the cost of what was in the link previously posted.
I have a few sets for OBS ready to go, and not sure when we'll have time to crank out some more.
Let me know if you're interested.
