i would think an aftermarket headpipe with the stock muffler would increase the HP without increasing sound? it would take a little modding to get the pipe to fit the smaller muffler, but i doubt it would be too hard.
and i doubt it would change the loudness of it much, maybe 2 or 3 DB's.
other than that, an upgraded carb, cam, porting......uh....i think thats it. maybe higher compression, but im not familiar with 4 stroke mods, so i dont know how to go about that one, other than a new piston. and too high compression = expensive race gas.

Aftermarket header without the muffler wouldnt really do much I dont think? Since it would be restricted as soon as it gets to the smaller inlet. But dont take my word, if you want to try it you could probably weld some shims on it and adapt it, or even a cone shaped piece of metal off an old pipe. Theres alot of stuff to do to it, but it wont get very technical without spending some dough. You could take the airbox lid off, rejet it and find a better flowing pipe, I just remembered you could install a supertrapp, white bros, or fmf megamax universal with discs to control the noise output too. Theres always the bigger carb, port and polish, hotter cam, high compression piston, stroker ect.

true, a larger headpipe wont give as much performance gain with the stock muffler as with an aftermarket, but it will give a bit more power no doubt.

10.25to1 wiseco piston...and a bolt in race cam make sure its "bolt in" and wont require different springs...those are probly the easiest mods

if you ever want to go big i know where to get a 452 big bore for 350-400$$ and it makes an incredible difference. i've never dynoed mine but with porting and exhaust people claim they make over 40hp

Budget you say??
Pop off the airbox lid, add one tooth to the front sprocket, pop on a 400EX carb and run a 450R silencer with the HRC tip.
It is NOT much louder than stock at all, and it can all be done for about 100$.

Thanks for the input guys. Like I said, low budget, I'm a poor collage kid. So a 400EX carb bolts right on? And what mods need to be done to get the 450R silencer to fit?

I have won at least 3 450R silencers for .99c. Another 25$ or so for the HRC tip.
You just need to warm up the rubber boots a bit for the 400EX carb to fit. I am able to run the 400EX main jet, 350X pilot drilled out a bit and the needle raised one notch. You CANNOT run the airbox lid if you jet it correctly. It has some really good great gains for short money.
The 45Or silencer needs a midpipe. I made my own mig welding the stock silencer pipe to the 450R headpipe and had to heat it up a bit to get the right angle. I also made alower bracket for the big 450R can. Some guys skip that part but it is not a light silencer and it needs 2 mounts.
Some guys mount up the silencer and head down to the muffler shop, a few guys have got one made for about 25$.
