Ya!! GP123 on smooth pipes or hype pipes!!! Key to a good midrange is headerlength and the smooths and hypes are extremely forgiving

But as Paul and Jack said, the cans are nice also. Should get you the same or a hair less performance than the muffs

Put it this way... Anything is better than those nasty muffs Dean!!

On Ed’s next 120cc he is doing muffs... you should do an exhaust trade with him LOL

Got ya! Thanks I'll go for the smooth pipes but will have to wait as I'm gonna get the proper headers.
Nothing in stock anywhere that I can find and honestly with my goal of flying this plane next weekend I'm just screwed anyways.
I think I may get out only 2 or 3 more days this season so it will be a winter retro for the pipes.

I've watched Lornes site for Hype pipes for a long time now and doesn't look like much happening there...

Yup...just let me know Dean...throw em in the mail for ya!!

I mounted the stock muffs and they fit in the cowl nicely, no half moon cut out, I cut the exhaust pipe holes as small as I could so there is less to cover later when I do the pipes.

You'd have thought that the GP designers would have realized that the muffler almost makes it impossible to adjust the low needle, it will be a challenge lets say....

I cut a massive hole in the bottom of the cowl for air exit, should be no issues with air flow now!!! Cowl feel lighter now too haha

[wingburner]

Okie Dokie Dean....definitely better using just the headers!

Ok so I have a serious question, I need a new home for my 20 cc dle and I see Pro RC has a ars 300 with a 67 inch WS, it says it was flown electric. Anybody know if this might work for me? Thanks.
