How to know? How to tell you....ha! ha!
Well, he must know how to tune the air/fuel ratio and the CO also. It is not just tune the idling speed. There is another screw hidden behind with a cover, covering it, if I got the carb right...... blush.gif

Yup. They tune itself accordingly. Thats why they have o2 sensor and smart ecu ensuring optimum burning. Some even shut off the injector and run only 2 cylinders during cruising or idle. Same goes to startstop tech.

Only read about the V6 of the 3.5L Accord on this.......

One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. The system uses the i-VTEC system to turn off one bank of cylinders under light loads, turning the V6 into a Straight-3. The latest Variable Cylinder Management system is able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads or four-cylinder use under medium loads.

OT again, better go back to Exhaust mod...... blush.gif

Mine is too old, I also don't know what brand already.
2.5" from turbine to rear muffler which is a straight through model.
Initially the bass sound more solid, by now the fiber glass may be gone, the bass more mellow and low.
Even though sound lower, but further away can hear, maybe the low bass volume gets transferred further..... blush.gif
