Cutting Corners and Chopping Pipes

I feel bad about asking a question that was already asked on here so I read all of the previous ones before asking this time. Sorry Dave, but your replies to the dumb questions are hilarious.

Ok, since getting this bike and deciding it is going to be my project, it has cost me quite a bit but so far so good. I just want to try to focus on cutting corners from on now where possible without sacrificing quality or performance.

So here's the deal and the question. I have a 04 GSXR750 with a Yoshimura RS-3 carbon fiber bolt on pipe. It looks great but isn't very loud. I plan on eventually getting a full system for my bike but this is the one that came with it from the guy before me so it works for now. Anyways, I was talking to a guy that had an 06 GSXR1000 and he had a CF pipe that he had actually chopped down about 3 inches shorter, took the insulation or whatever it is out the pipe, restuffed it, and then attached the end cap back on with threaded nuts and bolts and created a shorter, louder, mean sounding exhaust. My other friend with a 600 and a stock pipe just gutted his and it sounds loud and bad as hell as well. I've thought about trying both but what are some of the possible negative side effects that could have on my bike? I think I've heard it could possibly burn out some seals or gaskets in the headers or something.

What's your opinion, even if you could recommend another Yoshi pipe that sounds better?  

Well, if your going to do a quality job, then chopping your pipe I think would be the better alternitive.  Basically all you are doing is just reduceing your over pipe length.  wich will give you less noise reduction and less flow resistence.  I dont think that a shorter pipe will have any negitive effects on your egine temp or burning out any seals.

The objective of a muffler is over all noise reduction with out disrupting flow as much as possible.

As far as gutting your pipe, i think that all you would end up with is sound that could throw me into a seizure. lol.  

If you go too short the bike will not have enough backpressure to run properly. I would recommend starting with 3 inches.  

I used to chop down all my pipes on my old CBR900RRs.
doing it with CF is messy though—wear long sleeves and at least a bandanna around your face (bank robber style).
you could shorten it quite a bit before you have to worry about remapping the FI, but just remember to repack it. it's not gonna "burn any seals" or whatever. that's nonsense.
it'll sound better and look cool.
go get a $25 rivet gun from home depot (save the receipt). pull off the pipe, then it's a simple procedure: drill out rivets, remove exhaust outlet port, pull out the honeycomb tube and packing, run a piece of masking tape around the pipe as a guide, slice away (hacksaw or dremmel). then, cut the honeycomb to fit, rewrap it with your packing and put it back in. rivet the end cap back on. you're done.
finally, return the rivet gun to home depot for a refund.  

wrap the exhaust with masking tap where you will cut it, itll hell it from splintering/

dave got it on lock on how to do it, piece of cake. I do it to the stunt bikes all the time.

I cut my Yoshie TRS down to 300mm I repacked My can, I also Changed the innner perforated tube replaced the original yoshie tube with one from a VW beetleand repacked it sounds REAL KNARLY  

that's what i did when i changed the sprockets and chain lol. refunded the $130 torque wrench...work smarter not harder
