DOes anyone make a performance exhaust manifold that will bolt up to the ct-26? There are tons that make them for the t4 flange, but i haven't found any direct bolt ons for the ct-26

It would seem to me,
that an upgraded CT26, and a better intercooler
will do way more for performance,
than going to a shinny manifold with questionable longevity.

If your after better looks (nothing wrong with that),
you might consider getting your stock one ceramic coated.

After seeing the wall that our wastgate opens to on a stock elbow, I refuse to believe that our exhaust manifolds are super effective. I have an intercooler and I'm in the process of upgrading my CT, therefore when i install, i figured i might as well upgrade the exhaust manifold as well.

Get a ddp if you want to deal with the wastegate issue. If you are still using a CT, there is no point upgrading from the stock manifold. Polish the runners of the manifold if you want to increase it's efficiency - don't port them; all you accomplish by porting is losing exhaust gas velocity.

The stock manifold flows plenty well enough for what a CT26 can handle...even a CT26 that's been upgraded.

Get a new 3" elbow or a single piece downpipe as suggested.

Yeah i definitely already upgraded my elbow and downpipe. I was just using that as reference. Well I suppose I wont upgrade the manifold then! Thanks!

you know you can port out the stock manifold, if you put your finger up th ports there are a lot of restrictions, there is a guy local to me who does a fantastic job, pretty much a mirror finish, and there is deff a noticable difference in performance and spool time
