What is new in your little world?

[YourGrandpa]

I just got done installing a new exhaust system, intake and tuner on my Harley.

So you made it louder?

[Captain]

And slower :olo:

Funny memory just came flooding back...

In my youth a hundred years ago, did I ever mention I was a bowser monkey? You know, in the days before technology, 'plastic' and self serve at 'servos'? A time when we usually had fellas at garages serve you, putting petrol in your car and check the oil, tyres and clean the windscreen.

The memory was of me talking to a 'petrol head' and the time was well before 'rice burners', think hot rods and you're close... We were on about car performance improvements. He suggested taking out the baffles in the exhaust muffler of his car made it go faster

Now me, a little naive thought this had an essence of truth in it Goodness knows why but I could see merit in the idea.

Anyway, I spoke to a young and upcoming mechanic apprentice and he challenged the belief saying 'modern cars' relied on some obscure 'back pressure' from the exhaust to aid peak performance.

TLDR; don't fiddle factory fitting

Time to ask the question then: Does removing exhaust baffles change performance?

I bought an 2400mm wide workbench to add to my garage.

I think there's a fair bit of truth about back pressure being calibrated at the factory which helps performance but that's before you get into custom tunes and setups. Keep in mind, not every region is the same either, what might be good in Australia may not be great here in Canada in terms of performance and car manufacturers often tune their cars for use in many different regions which may not be optimal for all regions. If you mess with stuff like back pressure, assume you'll need to tune the ECU accordingly.

It is louder, but not obnoxiously louder. The stock exhaust was muted substantially and didn't have the Harley rumble that is widely associated with the brand. I like that rumble, so I changed out the head pipes and the mufflers, as well as the intake. Not only did I get the sound I wanted, I also picked up some horse power. The new intake looks awesome too.

Removing back pressure will cost you some horse power. Even though removing baffles and installing straight pipes increases air flow and sound, it also hinders the motorcycle's performance. Today's motorcycles have computer controlled fuel systems. If you make changes to the factory exhaust you need to re-tune your fuel system to account for those changes. The new exhaust system I installed increases the air flow out of the engine, but also has mufflers with baffles to supply the necessary back pressure. To accommodate the increased air flow out , I installed a new heavy breather intake. I also installed a Vance and Hines Fuel Pack 3 tuner. The FP3 gives you the ability to flash your bike's computer with a custom tune for the parts you installed. You simply plug the tuner into the ECM, connect via blue tooth from your smart phone, build a custom tune with the V&H app and flash the ECM. Or you can do what I did and have a V&H tech use an upload from your bike to build a custom tune.

Amazing technology these days.. ..

Sorry for the shitty pictures my phone makes, but here are some

All the way to the right is the "Assembly Square" set which my girlfriend is building. It isn't finished yet because a large plate piece was missing from the box. LEGO has awesome service for such situations though. You can order replacement parts for free. Don't even have to pay shipping.

That's awesome

I wish I had pics of all the 80s and 90s city sets I used to build with my dad and brother. Eventually I started building my own cities to house my massive car collection and created new sets by mixing and matching Legos.











These pics are from around 2004, everything's sitting in boxes at my parents' place in Finland now. One day I'll get a spare room to rebuild it in.

[Eraser]

Heh, very nice. All of my childhood LEGO is still packed in containers in the attic. When my kids get over their tendency to lose their own LEGO bricks all the time I might pull it out again.

[Pext]

Whoa. This is awesome!

If you're 5.

Yea, not sure about that

[phantasmagoria]

Mazda I love those pics.

All my childhood lego got given to a neighbor, without permission, when I left home :tear:

[Doombrain]

My kids are getting loads of lego for gifts and i've got to be honest, i love building it with them.

[Eraser]

Typical. Gramps seems to be the only one who's hating fun.

[Κracus]

His job is basically a lot like playing with legos.

Ironic that the person here whose cranium most resembles a block has a disdain for Lego
