Shortening exhaust - will any problems arise?

Hi all.

I have a carbon fibre IXIL pipe on my 00' zx9 I am thinking of shortening it to make it look a little better.

I'm guessing it will sound a little louder, but will it cause rough idle, running leaner or any other issues.

cheers

Yes, no, doubtful but possible, no other issues i can think of that adding a straight through wouldn't have already introduced.

I have the same question

I have a 93 ZXR-750 fitted with a Laser. I am thinking of shortening it. Will I have any problems? It has a K&N Filter, and has been jetted to suit..

Any help would be appreciated.

Thanks....

I cut the fuckin' pipe on the MFP12 in half ! It now goes twice as fast !! :lol: :lol: :lol: :lol:

well, in all seriousity, if you are already running a sports pipe (ie straight-through), the *only* difference when you make it shorter is that it will be a tad louder. If you have already jetted the carbs / mapped a PCIII for the current pipe, cutting 100mm or even 150mm off it, will really make SFA difference to your jetting - its not gonna run lean or fuck the engine or anything like that.

Short pipes look shit-hot. Here is an example....

*WARNING* - cutting a pipe in half is not as simple as it sounds. Be prepared to do some spot-welding. Have some replacement muffler packing ready to go. This job can take a couple of hours to complete, but its well worth the effort.

Hey Gos, Where can I get one of those OSHIMURA pipes? :D

Still haven't got around to chopping mine. Hopefully will get a chance on Monday. Everytime I look at the bike the bloody pipe looks longer.

Both barges look very nice.

cheers

thanks Russ...

that *Oshimura* pipe is really rare and uber-exxy. Unlike its common cousin, the *Yoshimura*, which makes appearances on bikes everywhere.....

The pipe on Hoffy's barge is the poor relative of both - the *Yoshimur*, basically thats the cousin that lives in the basement, we don't talk about it much, its an embarrassment to the clan.

:lol:

Yes, we call it the gimp...


Disclaimer - even though as it was my handywork that shortened it I take no responsabilty for the Yoshimur...

:lol:

classic

Shorty's done properly look the goods and increase the note loudness. Safety and asthetics, what more could you want?!

I dont want to touch the akra though - will leave for another pipe to get it done

Dont get a "Oshimura", get a "Yoshimur".. :lol:

Its the big brother of the pair, literally, and provides less "Flame Farting".. :lol:

Also, Dave you may have done the handywork on the pipe, but I put in the hard yards by watching you do it, whilst drinking your beer. :lol:

Carbon is a piece of piss, cuts real easy with a hacksaw, although I do recommend you do it with one of the old heads in the club that has done it before, there are a few tricks of the trade to help..or just get Dave to do it :lol:
