I have tried a MP5 but the engine seem peaky, I am curently running a FunTech FAI muffler, very smmooth, but will like more power. (The intake and exhaust timing are still stock)

This is for my Avant FX geared at 8.08:1.

Will a MP2 or an SB-17 be better???

The Outrage 90 size muffler is a good one.

Well more power could be aided by a newer engine...the HZ's are pretty stout. I had good luck back when I was flying my C-Spec with the Cline and Viperhead using the MusclePipe (older one....was it # 2 or #3, can't remember) It was the one they sold back in 2003 or 2004 ish.

Engine and muffler are long sold but it worked well, smooth, lots of power, good times

+2 for the Hatori SB-18.I had the exact same motor with the Cline carb and couldn't bog it in my Raptor 90 with the SB-18.

Well of course, but when people say they want more power a little increase is not enough (where is Tim the Tool man lol). The mufflers will make a little (and most is feel and needle sensitivity) but no huge power gains (well unless one was using the completely wrong exhaust).

So essentially I was just saying there is a significant difference between the CSpec and the HZ from having both but I did make a muffler suggestion though based on what I have used. I think you are prob pretty good with the Funtech though, nice and smooth

LOL I didn't suggest going electric though haha.

Its all good my friend.
