Re: making a f4i stunt ready whats the best mods?
Here is what I did. Check out my awesome abilities in paint.
Basically I eliminated one chamber.
Oh yeah, i cut the pipe just in front of the footpeg bracket, and then skinned off what I needed, then jammed everything back together. Don't chop through the entire pipe, just the outer chrome piece. Once that is pulled away, you then trim back the inner cheese grater lookin muffler deally, so that it all fits together.

hmmm weird because I don't even have that long pipe chamber pipe... Where I've cut it theres about 10" of nothingness! All I was gonna do is cut 5" off and not touch any of the chambers as they are all up the other end.. ah well guess I'll just have to do it and see what it sounds like

I cut the header pipe end off my stock can today and will cut the main body about 5" off and then just weld it back together and move the bracket
seems no hassle at all but is that all I need to do?? seems like it to me??

seems no hassle at all but is that all I need to do?? seems like it to me??the point of cutting both ends is to keep most of the packing area in each chamber to keep it as quiet as possible.
like I said earlier... on my latest project pipe I left the rear end of the can untouched.
I cut both the lower can body (about 3in), AND the 2 1/2 inches of straight pipe going into the can itself to get the best length reduction and keep most of the chamber.

used a hack saw to take the end cap off/out let off

and cut the other end as well both ends were cut just on the main body side of the welds
so with both ens off then cut/grind the hanger off
i chose my size as the width of a A3 sheet of papper
witch also gives u straight end to scribe into the steel
the edge off my cut was on the end cap side of a small box stamped into the can
near the honda logo
also havent had to mess with the internal pipe work:YEAH
except u got heat and bend the out let pipe down a little
heated mine with BBQ coals and a air line
i bent it till there was 3mm gap between the 2 main pipes
a good find was the way the end cap is made it comes apart into 2
place it over a off cut from the chromed can just i skin and hit it out
there a drain hole as well that help with leverage
and u can take out whats left of the old out let pipe and re use it latter to give u a gas tight 3 cambered seal we all hope
the hole is off center and helps to line up when u re assemble it
u place the this piece back over the internal out let pipe witch u bent a little with some hamering and adjusting
and weld round the internal out let pipe as it was before u grond/cut it off
then put the chromed S/S end cap over the top use a rubber hammer
should if ur cuts where straight weld it up with stainless steel rods
started welding it back up today i gota clean up my weld with a grinder
file and polish cos i s**k at welding i got lot of repect for thos who can
