Emailed mashmellow, he said that he has two prototypes but not for sell yet. Started searching web found one called gecker. Does anyone no anything about this exhaust?

Ya there still in workin on motors but mostly gokarts , there work suck ass anyways and the guy that does the welding only works part time last I herd , every time I called them same o storie are welder out sick this week , ok so get another fuckin welder you dumbass. STAY WAY AWAY FROM THEM.

gut your stock one

Guess I will just wait on a mashmellow

you can get the crossover and be like everyone else

Gecker's a douche & will rip you off.

Sent from my Droid because I'm trying to be as cool as you someday.

Bps cross over only really choice but he'll u put a different carb on it u gonna have to go with that anyways so bps would be easiest thing to do

BPS, or you can buy the "kit" from MM & build it yourself.

Or that but it costs about the same and u gotta do all the work so I mean I'm little lazy and lack of the right tools.

Me too, that's why I run a BPS.

Just get youa BPS single crossover and go with it

I am running one of the marshmellow prototypes and i love it on my 23GTR i noticed the difference when i installed it. it cam in parts and i had it weld. it was quite complicated making sure it was all lined up perfectly but once i got it together i sounds good and smooth.
