Hybrid exhaust

[2strokepowerhouse]

Hi guys I have a 3tj with a 600 foxeye engine fitted I'm just wandering what exhaust system would fit it would a set of r6 downpipes fit with an r1 can and link pipe ?

I just used the standard 4JH headers on mine, with a generic 4JH link pipe and can. It needed a bit of tweaking but it fitted ok.

I'm looking into having a new large bore stainless system made up specifically for hybrids if there's enough interest, if not, I'll just get mine done.

r6 headers do not fit the 600 t/cat or fzr600 motor they are way smaller(as i found out with a set of 5eb r6 headers) you can use the thundercat or 4jh fzr600 headers as they are very similar if not the same,ive used both on my hybrids,though i did have to have little bend of the bottom half of the headers with some heat and a big metal pole to get a snug fit!.you could get some thundercat stainless ones off e-bay for 130 quid new by motad -good value
have a look.....

Good value but not very sexy!

I agree with the 'keep manufacturing in the UK' bit though.

The thing is, is people spend hundreds of pounds on bodywork and blingy suspension, then chuck a crappy (usually second hand standard) exhaust system on the bike. I did it myself (well, except for the hundreds of pounds on bodywork and blingy suspension bit!) but surely, if you're building a nice bike then you want a nice exhaust system for it as well? It's not a lack of availablity, I* could get a batch of really high quality, hand made (TIG welded) light weight sprung systems made but they'd cost around £450.

I don't know if it's because there has never been much available for FZRs from Japan in any great amount, but we're really conservative when it comes to new stuff compared the Honda lot.

* or anyone else willing to pull out a couple of thousand pounds on some cool stuff.

I think it's more that the basic systems work well and the 400's use the exup. You could get a better pipe for .... say £450 tune the carbs at £200 but only get a relatively small gain higher in the rev range. Really you need to be tuning the whole engine and follow it through to the pipe to get the full benefit.

Lets face it a 600 conversion is a relatively cheap way to up the power by over 50% ... it's "free" if you sell off the 400 engine etc.

But this thread is about 4/6 hybrids, not standard 400s

If you were getting massive amounts of gain, then maybe £450 is ok, but to be honest, if it runs and handles well, i wouldn't much care what they were like. the money spent on suspension aids the bikes performance in an 'adjustable' way so is worth the cost even if it's just for rider confidence. As for fairings, well as long as they're in one piece i dont much mind having tatty ones, but again, it's personal choice, they don't make the bike better to ride or faster so i wouldn't want to be spending on them.

I think the same way, as long as the bike runs well and is safe to ride then I'm not really bothered if it's a bit shabby round the edges but my point was that those who do spend money on making the bike look nice then spoil the ship for a ha'pworth of tar by slinging a standard system on!

Since we're boldening things up as in the basic 600 system and the 400 system work well.

I'm sure you could talk to BDK and get tappered downpipes to fit the 600 block but as I said you'd really want the engine tuned to see a real gain. This probably won't stop me using something nicerer if I get the chance ... which of course I have
I'll see what I can do about the bodywork too.

Ah, sorry, I misread your post

I don't think you do need to do any engine tuning to see a decent gain from a decent system. If you look at the standard 600 headers the collector is crap and (mine, anyway) exit into a 45mm link pipe (and they were taken from a complete 4JH), so surely a thin wall system with a larger collector and link would be 'better' not just in terms of power/torque but from a weight saving point of view as well.

I know I keep threatening to sort my 4/6 out but I'm going to have to now, aren't I? BDK who?
