So roughly a 14 rwhp gain.

Can someone refresh my memory on Air/Fuel on these graphs? The higher the number, the leaner? Or the richer?

Higher = leaner

Lower = richer

If I remember right, I think 14.7:1 is the "perfect" air/fuel ratio (for gasoline engines)...and anything less is considered rich and anything above it is considered lean.

Edit: Damn, someone beat me

Personally, I like the sound of this exhaust very much. The only thing missing are dyno tests. Do you plan on getting any soon?

Also, since there are no resonators, how is the drone?

At an 80MPH cruise in 6th you won't hear the exhaust. If you punch it or downshift you'll definitely hear the exhaust, but I would say that there is no drone. I actually have some videos taken inside the car on the highway, I'll have to dig them up. The 370Z doesn't have the quietest interior so in the video you mostly just hear the wind when on the highway.

I don't recall the exact weight, but I remember it was about 4lbs. lighter than stock when we last weighed it. There are a few minor modifications we're doing for the production units to make them better so we've been waiting for the actual production unit to get an accurate weight. We're hoping to make the production units even lighter.

Sounds promising. Can you explain the shops name?

I was hoping to plead the 5th, but let's set the records straight..."Boombop" is a play on an old jam by Shaggy called "Boombastic", no relation whatsoever to Hansons. At the time, my brother and I were just selling random stuff on eBay, but the name stuck and it was different so we went with it for our company name.

"The Boombop Shop" just has a nice ring to it

In any case, hopefully we'll have a detailed post on the entire exhaust posted up later today. Keep the questions coming!

Thanks,
-Ben

Are you planning on including flex couplers?

Are you referring to the metal flex pipes/joints? I was never a big fan of them and our fabricator/designer/mechanic said it's not needed so our's does not incoporate them. We use a slip fit between the X pipe and the mufflers so it does give you some room to make minor adjustments.

A few requests for pictures of the exhaust installed, best I have right now is a video we took during the dyno session with the prototype exhaust. Just uploaded on YouTube, figured I'd post it before AK370Z found it!
