Tip for slightly quieter exhaust

It didn't seem to affect performance at all,in fact this Sirio 27R seems to gain power with each tank but it is still loosening up.Just coming up to 1 gallon but not bad going seeing as i've been running it less than a week.

I have to say this engine is superb,definately the best i've used by a million miles.I was totally fed up with nitro before trying this engine and had sworn to convert everything to brushless but now i'll be keeping one as nitro.This engine is so nice.

Not all big blocks are the same.Before you give up on nitro, give a Sirio a try.

....so this means that there is a solution to very high rpm noise is lower.....and can this solution be solved to all nitro cars?????? if possible for a nitro mt-2 then please notify me... thank you

Only made a small differnce,just kinda took the shrillness/high frequency down a bit,it was on a loud pipe.i don't think there'll be a way to solve the high noise levels,they need the pipe to resonate as i understand.I don't have any neighbours for a good 1/2 mile or so,so i used to keep the nitro for the crappy weather, but i gave up on nitro stuff in the end when it annoyed me for the last time.
