Custom Y pipe gen 4, Anybody done one ?

Recommended Posts

Anybody here had a custom Y pipe made up ? I know there are some rather nasty fitting ones available from ebay. But I would love to see pictures and hear what the improvements are like. Who fabricated it and so on....more so if you are in Sydney

Well to be honest it aint sparkling show quality beautiful.....But I like it. Simple yet effective.Very much what I had in mind for mine when funds permit. What sort of $$ would one expect to pay for something like this ? Was it done in Sydney ?........did you notice power gains ? And at what sort of revs did the gains seem most noticable ? What effect did it have on fuel economy ? The ECU didn't mind the swap at all ?

Well that cost $220 when I got it done. If I were to get it redone, I would have gotten them to put the flex pipes on it before the hanger like they should have.

Power gains, maybe very slight at the top end but there was a flat spot in the 2-2.5k rev range. Fuel economy is never affected directly, just indirectly when you want to hear a bit more noise.

ECU was fine with it. But in saying that, my ecu was weird and is fine with pretty much everything even 6psi boost with supra injectors and bigger fuel pump when it should have been running so rich that it shouldn't even be able to idle.

Well the design of the OBX seems to be the best for efficiency that I have seen. But I am not hearing any good stories regarding the quality. Apparently they have fitting issues ( which I think John Su experienced ) and the metals they use arent the best either. But the design itself seems to be the best I have seen. See any decent power gains John ?

Not saying it's not good value for money, but if you include the "customisation" needed to fit it after the initial outlay + shipping the value may not be a good. However I'm pretty sure you wont be able to pay the same amount to get something like mine made up. The guys only charged me $65/hr + piping.
