Opinions Please

[Burnout]

Trying to come up with something interesting with my builds exhaust.

Here is where iam at .

opinions really needed .

good bad or indifferent i really could do with some input

I like it. (I'm assuming that the welds won't be smoothed out.) To really pull it off, the tiggin' will have to be top notch though. Bad welds will stick out like a sore thumb on a feature piece such as that. What way are you thinking of slinging pipe 1 and 4?

@Jaydee ye kinda have 1&4 and 2&3 both going 2 into 1 and running either side of the underside

That's awesome fabrication, but don't you want all 4 hearts beating to the same drum? Most engines like that, tuned length and all.

If it's going to include a pair of  huffers, well cancel any thoughts from me, I know nothing of Turbo world.

Nice, as said welds must be spot on.

Length is a matter you really need to consider.

[bluedog59]

If you visually scroll out the downpipe lengths they look around about the length a 4/2/1 would start to merge into 2. Have you got them all the same length ? One way to check is to plug each pipe on the bench and fill them full of water. You can then compare their volume and it gives you a visual idea of any length adjustments required.

probably not the best way to check....they'd have to be fully welded to hold water......you could use sand......or even better a tape measure 

[vizman]

form follows function, so if you're trying to re-invent the wheel I'd say your pissing in the wind tony....but if you're going for style over functionality then it's all down to what you find aesthetically pleasing.

I was presuming that and as a final check. The tape measure will get you very close but volume will fine tune.

try running numbers 1 and 3 down one side and numbers 2 and 4 down the other....would make the lengths/volume more equal.....ish

 

[vizman]

 I was taught to use calculation to find volume, just like when you'll have to calculate the difference in the amount of water used to fill each pipe....

...yeah I'm being a cock

I was thinking that way as well m8

Of course it wouldn't be an issue if you ran 4 separate tiny Moto GP style cans on the ends,

might be tricky to package though.

Someone on here is bound to know what lengths suit the engine spec.  Different lengths tend to alter the power delivery, more top end or more midrange. Though it's quite possible to create huge flat spots in the midrange if it's not quite right. That's from personal experience on the Phase One Suzuki's. We think that we're collecting at about the right length, but are then dumping into a Mid-pipe tube that's probably too big for the exhaust gas speed and it's stalling in the pipe.

looks awesome
