I went by Rainbow muffler earlier today and they can't mess with 3" piping. The guy said the piping is too large for them to flare

Looking for a shop that can handle the task and at the same time weld the aluminized kteller kit.

The set-up:

DTR header > kteller 3" piping kit > Vibrant 18" resonator > Vibrant 3" stealth muffler

Some pics of the system:













I took the header (piece that connects to exhaust) off and it's 2.5" diameter as seen here:



Entire piece:



Thin gasket not quite large enough to mate with the DTR header:



kteller flange also not quite large enough:



Closer look at the misaligned holes:
