Best exhaust?

[Kempz44]

Hi guys (and girls), I have a 2000 Honda CB400 Super four (vtec model) and was wondering what you guys think the best option would be for an exhaust replacement (currently factory). I wouldnt want it really loud but not too quiet either haha, any suggestions? And would it increase horsepower?


cheers.

On your full license are you .. ???

[Kempz44]

nope im on my restricted :(

LAM's motorcycles must remain stock standard to retain approved status. No modification to increase the power to weight ratio is allowed.

So long as your new pipe doesn't have a Yoshimurakrapovic sticker all over it no cunt's going to give a toss. Make sure you buy locally.

Oh no 2 years of a bog stock 250cc. I was hoping to (maybe later) re-jet and add a slip on since I couldn't get an R6 on my restricted. Fucking Lams. It does make sense though but 2 years on a stock 250cc? Its plenty fast for me now but the day will come when I'll crave some real power.

A) You won't get any more power out of a 250 no matter what,

and B) if you read LAMS shit, they don't care about pipes and whatnot on 250s. Basically, 250s you can do whatever to (pipes rejetting ect blah blah ), but anything 251cc-660cc you have to leave stock.

Short of throwing a new motor in there entirely, you realistically can't get a 250cc 4stroke motor over the 250kw/tonne limit.

PS is your bike even working yet? :laugh:

[SNF]

double post again - how the hell did I do that?

[SNF]

Yeah its not perfect but its ride able been to work on it a few times. Better than it has been that's for sure :laugh: Saving to fix it properly once and for all (I hope).

[Kempz44]

Shit i didnt even think that modifying it would be an issue, but i guess it makes sense, will just have to wait till i can buy a kawa z750 :)

Cheers guys.

I've never seen this mentioned anywhere. Where did you read this?

LAMS-approved motorcycles

From 1 October 2012 the following motorcycles are approved for use by Class 6 learner and restricted licence holders.

LAMS-approved motorcycles include:

All motorcycles with engine capacities of 250cc and under, except for those on the LAMS-prohibited list above.


Fully electric powered motorcycles with a power-to-weight ratio of 150 kilowatts per tonne and under (this includes all fully electric powered motorcycles registered on New Zealand's Motor Vehicle Register as of 1 June 2012).


All motorcycles manufactured prior to 1960 with an engine capacity of 660cc and under.


The following list of motorcycles with engine capacities between 251cc and 660cc - these motorcycles must be in standard form as produced by the manufacturer. They cannot be modified in any way to increase the power-to-weight ratio.

In regards to this improved power to weight ratio in for LAM's, how exactly are they going to test for this?

Is it just if you modify your bike you are no longer approved? (as im sure in a lot of cases just putting on a new exhaust is not gonna give you more power without some changes to the fueling?)
Or are they actually going to implement some sort of certification system similar to what they do with cars?

As i know if I was still a learner I wouldn't want to have to stick with a stock can as in most cases you just want something louder so that other traffic notices you.

Try Cycleworks? They are in wellies I think?

FJ, I keep saying this all over the forum, the CB400 water cooled bikes (the post 92 CB400 Super Four and VTEC) are NOT LAMS legal. But due to nobody looking at the CC rating, everyone thinks they are :nono:

As for mufflers, no it's not really going to give you a heap of power, but on a VTEC model with a slip on, re-jet and decent air filter you should be seeing around 55rwhp, factory they manage 52-53rwhp.
Something nicely made, like a Neptune muffler would suit it, there's a huge amount of after market parts overseas you could import too.

If that is the case why does the lams approved motorcycles list include the CB400SF and the CB400F at 408cc as approved?

(sorry thread hijacking a bit)

The Watercooled post 92 are 399cc, the ealy CB400 etc are 395 and 408 respectively.
The CB400 Super Four Project Big 1 (bloody mouthful, that's the 92 onwards, I had one) tip in at 152kw/tonne by LAMS rules. The VTEC, in the real world is more too.

Easy answer, is if your bike is 251cc-649cc, if it has any modifications, it isn't LAMS legal. End of.

250s can have pipes and whatever, but if its a LAMS bike over 250ccs, it cannot have *ANY* modifications. Thats how they got out of dealing with roadside testing. If it's modified it's not legal.

I have a 250cc bike that's kind of slightly 589cc, can I be LAMS legal? :baby:

If it has the 250 stickers it's ok :niceone:

Depends on what your rego sticker says! :lol:

[ducatilover]
