Smaller Header Pipes

[bungbung]

I was told by a few mates at school (so this probebly isn't the most reliable info I've been given) that there's likely to be baffles in the header pipes. This true? If I made a replica set of header pipes without baffles, would this change performance for better or for worse?

They're pulling your leg. The only place you will find baffles is in your muffler.

Baffles are placed in a controlled area where they will be most benificial to both the high and low end, the can, some headers have kinks in them that provide a baffle type effect... But not to the same level..

Screw the crap, get the can, gut it, shove a perferated tube in it and run away laughing...

Perferated tube? Sound interesting

I wonder if you could make a Turbocharger/Pulsejet exhaust system

Baffles in the muffler yes,but some bikes have a restrictor in the header pipe,part of the derestriction process is to remove these.

How do these restrictors work? Are they like baffles?

Normally washers or kinks. (mainly in smokers)

Ah stuff it. I'll just remove the header pipes yes I relise how stupid this would be, I did it to a Mitsi Chariot

Sounds good but kiss your valves goodby, like I said perferated tube, no packing.. legend sound.. I just tested mine.. me likes.

What's a perferated tube and how did you do whatever to your muffler? I thought modifying my stock muffler or debaffling it would result in sluggish performance?

Yeah, one of those on the CBR would be sweet

In theroy it depends what you want, the debate of backpreasure is so hot aired I wont get into it, All I can say is your going to loose low end (in most cases)...I got the exhaust of taka mc wreckers they have them on trademe, I just drilled it out and took out the packing and am trying to fit it on to my pipe cleaner than the current method...
'm sure motu will be more insightful - because i am a young testosterone driven teenager, Its all about sound... Apparently...

Low end is already crap so I keep above 14k (on the track, I'm more conservative on the road) so if I can make top end better from sacrificing bottom end, I'm not really losing in the end

Also I was thinking of changing the rear sprocket to one with a few more teeth, but that's another story

[John]

I would be more inclined to drop the front a tooth dunno why, just because thats cooler ...

Does the CIBBER have a 18rear? try to slap a 17 on it..

I havent had any full riding experience with my bike running a proper straight through but I would imagine it wouldnt be fun at all, tristan runs a budget straight through ask him.. He cant really make up his mind about it lol :\

Not sure what it has at the moment. I wanted better accel so I could get ahead of the RGs at the start instead of having to back off and wait untill I got to a straight to pass them. Although, the problem with all these mods is they're not allowed in streetstock anyway, but then again the VMC don't scrutineer the bikes

[John]

thats not very sportsman like of you! *spanks*....*spanks some more*....*enjoys*

[onearmedbandit]

You'll find it easier and cheaper to drop one tooth on the front rather than getting a sprocket with more teeth at the rear. Why? Because you shouldn't have to change your chain.

[Coyote]

thats not very sportsman like of you! [other bullshit typical of John]

But in the first race 2 stupid RGs were riding together and I couldn't get around them, second race at the first corner a ZXR tried to swipe my front tyre, fortunately I backed off in time or there would've been a major pile up, and the third race a RG crashed into me and thats what has sent me off the road and track for 2 1/2 months! I need to actually qualify (they stopped me from doing that as they had to explain to beginners like me what each flag was) and get ahead of them so they can't hurt me or slow me down
