Howdy folks.

Was out earlier today at Atlantic Motorsports in Gaithersburg, MD where I had them install the Berk high-flow catalytic converters on my Z. I had them do a before and after dyno on my car so we could see what the gains where, if any.

My Z already had the Stillen cat-back exhaust, and I don't have any dyno numbers for that add on. This is just "pre" and "post" Berk HFC with a Stillen exhaust.

I have to say that I am pretty stoked to add almost 8 hp and 6 ft/lbs with such a simple upgrade. In addition to the power increase, the sound is amazing. Very little rasp at all, just a solid baritone note that is subtle at idle and wails at full throttle. Install went smooth; just one broken bolt.

Nothing but good stuff to say so far; I wish I had done this upgrade sooner.

EDIT: trying to get the dyno charts to load up in the post... grrr...

In any case went from 289.6hp and 243.8 ft/lbs to 297.2hp and 250ft/lbs. Very impressed with the flat torque curve of this engine.
