Nice gains. You can use the CAN Tool in autodelete mode as a DPFIX. One question though. Why were the stock DP runs done a day after the catless DP runs?

because the stock dp were put on first and dyno'd - my bad.
Berk had to remove the dp then dyno'd the next day early.

Berk want'd to use my base i had from another dyno shop.
Bryan didn't know i dyno somewhere else besides EAS.
which would have skew'd the numbers. It was a good idea
that they base'd at the same shop (EAS). good call.

Any specs on that Berk 1'er? What tune do they have and how much power? Looks like a real sick car.

Nice gains OP, looks like a quality DP!

amazing happens. If the smell gets to me,
which it hasn't, i'll simply get a used N54 exhaust
and slap that on - it has a set of cats on it.
I can honestly say that those secondary cats take 70% of the smell away! I have yet to idle my car in a drive through and actually smell something. I would idle my car in the garage with the same smell as it was catted.

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

The n55 xdrive comes with the n54 exhaust which has secondary cats just in front of the rear wheels. A small cat on each pipe. Works great and sounds amazing and smells less

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.

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.

berk catless DP hold'n up very strong after 5 months of
daily road use.

beat it up every day.

sometimes, i'll put it on MAP 0 of the procede and
drive nuts with it. CAI intake and DP raw without
turbos.

single turbo + catless dp sounds amazing.
Berk ftw.
