Hey Bryan, same here.
Crew? More like good friends.
Never thought of calling ourselves as
a crew.

Thanks again for developing
for the n55 platform. The dynos
helped clear up some unanswered
Questions for me.

Frankie, I have the exact stock exhaust as a n54 it seems so it should fit yours.
do you have the whole n54 exhaust? mufflers and piping?

where are the cats located on the n54?

I like this option, as opposed to catting the downpipe
Like sloppy said. Cats are on the mid section - I believe they're 600cel cats. I believe u can get high flow cats that are 200cel or 400cel. Choose ur poison.
