[2LZ]

Ok...so I was thinking today....there's no reason not to get full tuning ability out of this baffle setup. Like with a Super Trapp, you install and remove plates to adjust backpressure for tuning purposes, this little baffle offers much of the same ability but instead of removable plates, you treat it like a recorder (flute type instrument). It has a movable plug. :-)

So, back to the drill press and I drilled as many more rows as I thought necessary to achieve prime objective, plus, every other hole I drilled a tad larger to help with the fine tuning, minus the first three rows. Anal? Oh yah....but fun all the same.

Theoretically, the more back pressure (more holes you block on the flute), the less top end you'll have, while on occasion gaining mid-range or even a little low end in a carburated model. Hopefully the O2 sensor will play.

I took it out after opening the baffle all the way (plug installed in last location opening as many holes as possible) and man....it really opened up the top end (butt dyno). More frisky and crisp, especially between 6 and redline. Drawback? It got a little noisier but not a ton. Just more shrill. Tomorrow, I'll move the plug up to block off two rows of holes and see what that achieves. It SHOULD lose a little of the top end but it will probably quiet it a bit also. We'll see.

This is fun............ "2LZ at Play".
