stealth mods

[RideRed04]

Just wondering, has anyone done the carb/bore/piston/cam thing, but kept a stock exaust? I was thinking, no way a full system can compare to the same amount of money in the stealth mods, but everyone pipes it. I just think its cool to sneak up on people....make them think after you wipe the grin off their face.:devil

I've tried the scenario you're speaking about. However, anyone with half-a-brain knew I was lieing and said so.

I tried keeping the stock exhaust on my 400 after doing a 416 10.8 to 1 and a stage 2 Hotcam... But I had a slight "bog" that I could not get rid of. The bog would get worse when I attempted going up hills. I did notice a slight improvement with the airbox lid removed, but that was not an option for me. Needless to say, once I put a slip-on... Problem solved, no more bog, but a lot more noise!

Note: I did all of this with 22" rear tires and a 14 tooth front sprocket... I did not attempt going to 20" rear tires to see if the "bog" would still be there... But I am sure it would have improved the performance versus the 22".

I know I am struggling with the same issue , really want to run with stock pipe on the 440ex listed in my sig. but losing power wish some one could devolp a pipe that was middle of the road,balance between resonable noise and performance.sorry sp?

i was thinking it would probably be quieter if you only do the first step of gutting it or the second step but not both

here is what a gutted muffler would look like

[phatswinn]

yea but with my idea they still see the stock silencer, and it will be quieter than theres if they have a pipe:devil :rolleyes:

I gutted a stock muffler, and gave it to a friend. I never tried it. He said he thought it lost power, but his bike was a piece of crap, and never could come close to touching mine when they where both stock. I believe he sold his 400 with the gutted one on it.
