Brozz exhaust

[Megadan]

Apologies, Hancadam, for the above post in your thread. If you so desire you can have it deleted by an admin and I wouldn't mind. It just had to be said.

No apology needed, none of the discussion bothers me.

Back to our regularly scheduled program...

Hancadam, since I have this freakish need to make brackets out of scrap, I ended up mounting it like this on Mrs. 2LZ TT250. I thought it turned out cool and I also fulfilled my bracket fetish. ;-)
My main concern was to have the muffler spaced out enough as to not cook the license plate plastic holder...which has been done here prior.

Does wrapping up to the muffler help with preventing oxidation?

Also too bad nobody has a motorcycle dyno.. I wouldn't be surprised if it actually reduced HP or torque without very specific valve and jet setup..

That is definanetly a more sophisticated solution then pounding it in to submission with a rubber mallet like i did lol. And for the record my rear fender melted in the best place for it to, the license plate covers it up. And for dual sports question it helps the exhaust gases travel through the muffler better i wrapped mine for the specific reason i dont want my pants to catch on fire or burn my calf while going down the road. Everytime it rains it will smoke for about 5 minutes until that moisture burns off. Every time i come from a wet ride off road or get caught in the rain i have people honking thinking my motor is about to blow up but they give me more room on the road so win win in my opinion

From my own experience, once you sort out the jetting after adding an exhaust, the mid range and top end power do definitely improve. A majority of that is thanks to the lack of the catalyst in the head pipe, which is ridiculously restrictive.

Further proof would be in the gain of about 5mph with no other changes to the bike being made besides jetting. Mikuni clone properly jetted on a stock bike would do 62-63mph vs. 67-68 after the exhaust and re-jet. Same 17/45 sprockets as it had before, no other changes made.

Simply slapping on the exhaust otherwise wouldn't likely gain much of anything as the bike gets lean pretty quickly.

Here is how I hung mine

Exactly why I wrapped Mrs. 2LZ bike. The last thing I wanted to hear was how she burned herself.

"Theoretically", wrap makes the exhaust gasses travel faster but with the huge displacement, fire-breathing, untamed horsepower of the mighty CG motor, I'm sure we're just a mod away from 11 second quarters. ;-)

One of our old members had a dyno. Here's his Qlink XF200 after some minor mods.



Here's an old member who dyno'd his Roketa DB07a. (CG200 motor)

I will always wrap my exhaust at least from the rear slip joint to right before it makes the bend back to the head. Outside of the practical reason of no leg searing, it helps cut down on radiant heat to the carb and engine a bit as well.

Im thinking ill be getting down to 9 seconds on my bike in a week or so red adds 5 horse.

Here's a quick clip of how it sounds.

Always wondered how loud these ebay exhaust are. Sounds kinda loud in the video but how loud are they in person on the road and on the gas?

My exhaust on my Magician is real mellow at idle and not to bad at 3000-4000rpm, but boy when you get on the gas man is it loud. One of my Harley owner friend took my bike for a ride and when he got back his first words were " man this is loud" and we all know how most Harleys sound.

[Hancadam]

For me, it's right at almost too loud. But what makes me happy with it is how good it sounds. It sounds like a bigger engine.

Thats just how I feel with my exhaust sound. Mine also sounds like a bigger engine. I would say maybe a mini Harley lol.
