After reading a few threads about performance exhaust on 4 stroke 50cc engine, seems that it is not really the best option in modifying your scooter. I learned that performance exhaust is more effective in 2 stroke engines.
Well, a couple of months ago I bought a used 2009 Agility 50 from an auction. The scooter was in nearly perfect condition...except it was missing the plastic muffler protector.
The dealer wants to charge $42+Tax/S&H for this part. And If I was to buy the whole OEM exhaust, it was going to cost $80+Tax/S&H.
I think either options is kind of expensive plus I don't really fancy the OEM exhaust (looks too plain).
I tried looking for the part on ebay hoping I can find a good deal on either a new or used...but no luck.
So I was wondering what my options are on exhaust systems for under $150. I should mention that I'm will be replacing the stock main jet and put a #85.
So my set up will be: (de-restricted CDI, de-restricted boss face, 5.5 gram roller weights, #85 main jet, EXHAUST???____

I see... I was hoping for the 138.00 version. The cheapest I have found is http://enviromoto.ecrater.com/p/8025586/leovince-handmade-titan-exhaust-kymco (http://enviromoto.ecrater.com/p/8025586/leovince-handmade-titan-exhaust-kymco)
That enviromoto site seems pretty competitive as far as pricing goes.
I'm in between getting this: http://www.enviromoto.ecrater.com/p/3956702/stage-4-72cc-power-pack-139qmb-a (http://www.enviromoto.ecrater.com/p/3956702/stage-4-72cc-power-pack-139qmb-a)
and this: http://www.enviromoto.ecrater.com/p/3955867/stage-3-power-pack-72cc-big (http://www.enviromoto.ecrater.com/p/3955867/stage-3-power-pack-72cc-big)
If I go with the Stage 3, and a K&N air filter, I've already order the polini variator kit, and it comes with rollers, so idk if it's worth the extra 49 bucks for an airfilter, and a new jet and spark plug. What do you guys think?
-
..if you install an aftermarket exhaust, you MUST open up the air intake...(free-flow air filter)...
..and your main jet size will approach 96-100...
-
i gotta agree with wordslinger...youll be glad you did...i have a zx and was a nice difference... but words ag hauls ass........i seen it. ;D ;) still jealous after that vid! :'( ::) ;)
-
..but there's been several ppl here that did the exhaust without the filter...
..their tuning pains were terrible!!!
..gotta suck if you want to blow!!
;D
-
:D :D :D thats one way to put it... ;)
-
With a 4t i think you can get close to after market performance with some well placed holes that cost you nothing ;)
-
well placed holes...? Pictures? :o
-
I don't have an agility but here's an s200 i'm playing with, the cap is removed and a few holes. Pay attention to your jetting if you do this.
This improved my overall flow made it sound a little meaner and gave me some pickup all the way through. Cost nothing!!! :D Well almost I did upjet and run some larger rollers plus removed my air box cover,worth every bit of it.
Don't go crazy try 3 to start,I like using 1/4 holes that can be plugged easily with some self tapping screws if ya go overboard.
I could probably go with a few more but the jetting is about right as is so left it alone till i get the belt i want to run.
-
Thanks man! that's awesome. ;D I think I'll try that before spending too much on exhaust. Especially for a 4T
-
For a 2t the pipe is worth every penny of it. With the 4t you just need a little back pressure and some tuneing for good results. There may be a bit of trial and error but easy to do.

..wow...ain't that the truth...
..i've removed my exhaust's catalytic converter, and drilled 4 3/8" holes in the bottom of my stock exhaust...
..thru it all, it was a tuning nightmare!!!
;D
-
Ha! but you did get results in the end. I may not have started with the cat though ;D
-
..no, if i had it to do over, i would not have removed the cat.....

I like dealing with enviromoto, Jeremy is a great guy. Make sure you mention you have an agility 50.
I didn't and I got the wron jet size... flow and tap size.
One quick call later and he agreed that it was the wrong physical size to fit, and that the jet was way too small for the a50.
I recieved three new jets in the mail yesterday. a 112, 115 and a 118.
He thought an 88 was much too small for it. so word... you running over 100 isn't too weird.
