Looking for decent extractors and 3" exhaust for rb30efi

[lars04]

Where's a good online shop to get extractors and a 3" mandrel bent exhaust looking for some with the exhaust temp bung in it already

Check ebay.

3" would be to big wouldn't it, unless I have motors mixed up.
Thinking a 2.5" would be perfect

Yeah, I haven't seen an RB30 with a 3" exhaust, yet. Bit of an overkill I think.

[lars04]

It will be getting a turbo put on it in the near future so 3" would be a perfect size I think

if your gonna turbo it soon dont bother with extractors etc just wait until you turbo it

as others have said 3" will be too big for a rb30 naturally aspirated you will loose power torque down low and get poor economy
also you will find most extractors only have a 2.25 or 2.5 inch outlet

Ahhhh bloody good point!!! Didn't even think of that, when I do turbo it I should be able to get a 3" dump pipe Yea

Bigger is not always better. The exhaust(extractors, exhaust pipes, muffler, etc) need to match the type of engine, be it stock or moded with turbo etc.

you'll get good gains from going up to a 2.5" exhaust

Post turbo can be as big as you want.
