look at the STS pipe its only $40, one piece pipe its very durable saw a car that got hit on the pipe side didnt make a mark on it

sts stops producing this pipe.

16% nitro....try 0.3mm shim first

Nothing can not be hidden to your eyes.....

and if hec is not in stock, what do you think about the pipes I own (Sirio and Nova), or Hong Nor X12?

Nova is ok. Shark's also not bad. RDLogic perform very well....there are too many pipes,you may need to try

I only have problem with LD3's stock pipe(come with box).abnormal back pressure and hard to adjust.Also it is a bit too long so fit for small tight track.Some people use it and feel not enough top-end,so just lean it and lean it till....engine die.Then blame STS suck....

So, are going to send me some stikers? Or I have to buy whole engine?

hey srry to get off subjecti just wanted to know what he 2 bearing sizes are in the engine because i am going to replace them with ceramic bearings. One more question does the d5 6.5mm carb fit in the rs5 and is it worth buying?

MR6801C & MR607C.
I have tested Boca on my STS for a while and work fine.

If your crank case is black old version,the new carb can't fit.

i have the newer rs5 with the silver case. so its all good?

Yes.

I am going to be using 20% nitro fuel. Do i really need to change the head shims to 0.4mm?

The STS pipe are still in production, I posted a question about the pipes on Teamcrc.com, and John replied that they are still being made and in stock. Since I am planning on getting one.

thanks Jason

Bought mine off ebay sometime back, I think it was < US$40.
Great Stuff !!

how do you like the sts pipe so far
