resonator delete pipe
 

what is this and its job???

cheers kyle

On which model?

oh sorry my98 turbo 2000, iv got a fmic and apexi induction. but heard of people with these delete pipes.

cheers kyle

Guessing it's just an after-market pipe section with no resonator in it. Same principle as a decat (catalyst delete pipe)? Releases a few more dB but no ponies.

Ah, it's earlier classic's that have the resonator delete when fitting the Apexi filter.

It's in the pic below;

Something similar, for your car, would be this;

All assuming I'm correct on which resonator.

is it something i need or will the car be ok without it??

thanks for the replies kyle

AFAIK: The standard intake takes a feed from under the bonnet above the radiator, feeds that into the inner wing on the driver's side, then back out into the airbox. In the inner wing is the resonator, a large plastic box filled with foam. The delete pipe gives a direct link from the air intake feeding into the wing, to the pipe from the wing into the airbox (which can be seen in the picture above, not connected to anything), removing the resonator box in the process. It is claimed to give a few bhp more, but it's disputed. It increases intake noise a little, since the purpose of the resonator is to dampen that noise. More details here:

If you've got an apexi induction kit then it's not an issue for you, but you may or may not still be carrying the resonator box around with you if that wasn't removed when the apexi went in. It's not heavy, and a bit of a pain to get out

Looking to do this on my Impreza. From looking at this it looks like you just remove the box then contact a section of rubber pipe to replace it?

Jay, you'd probably be better off taking a feed from the bumper area to the pipe that connects to the air box. You'd have to get creative and cut the pipe feeding the airbox though.

Alternatively cut the part circled in the pic, away from the resonator box and cap/block it where it's cut. I'm not sure what the air flow would be like though.

Right this is a job i need to tackle asap. So there's foam inside the resonator? As i need some induction noise.

No, it's literally a plastic box. It works on the principle of sound waves cancelling each other out at certain frequencies in a certain size box.

Two different subjects being discussed her. Inner wing snorkel and resonator on early v1/2 cars.

There used to be a 180 degree pipe manufactured that could be used with the existing inlet duct but now long forgotten

Can you link me to this particular diagram?
