VFR 800 vtec gutted exhaust

Semi gutted exhaust, end caps sliced off. packing and wire mesh around the baffles was removed. The baffle closest to the front of the cans was the only one removed. most noticeable on acceleration and fairly quiet at highway speeds. Not bad for 15 dollars to have the end caps TIG welded back on with stainless steel wire.

did you have to re-map the bike or tune it?

@hondasniper250 I did not purchase a power commander and remap the bike as you should do. No power gains were made from this modification, just a difference in sound. The VFR vtecs are quirky. I think they could have done a much better job than the factory tuning. It is jerky, snappy, and has a flat spot before vtec is engaged. I think the blend of fuel injection and stricter emissions standards is a part of the problem.

@engraym Do the O2 sensor delete mod, it greatly improves the low RPM smoothness. Gutted muffler and O2 sensor delete are the only 2 mods on my '08 VFR and it's been great ever since!

@aracnid007 This is one thing that I was going to try with the bike but I sold this bike over a year ago. I miss it but I am having too much fun on my 78 CB750 now.

I would have to hear it live as it sounds like an old car with a badly blowing exhaust on tick over, not too bad when throttled though. I do like the sound of my VFR as standard though, love the V4 burble.

sounds not so good, maybe it sounds different in person?

@jiitee The V4 requires 87 octane and this is what it got after I I used a few tanks of premium before discovering it only needed 87 octane. There was no difference in performance at all. Octane is not a level of energy/power but a resistance to detonate under pressure. The flat spot is only problematic with light acceleration. It is written into the fuel/spark maps to do this right from Honda. Full throttle acceleration never had a noticeable flat spot.

[jiitee]

Use Shell V-Power gasoline and you don´t have flat spot before vtec. These low octane gasolines are pure shit for these bike.

It's good, If you enjoy your bike.

@pcsullog If you told my welder, who put Hondas welds to shame, this was a home made demolition you would be insulting a true artist. This exhaust got nothing but compliments and the stock cans are the only ones that look right on the VFR as well. I enjoyed riding this bike for a season but it just was lacking power that should come from a V4 honda and the factory FI "off/on" throttle response and flat spot before vtec ruined the bike.
