Maybe im too old, but I dont really like the sound of my o2 dump. I love all the benifits of running one. It just sounds to raspy like I have a faulty exhaust.

I was wondering if there was a way to modify the sound just a little?
Would adding a resonator diminish the efectiveness of the dump?
Does anyone make a resonator that slim?

 

You would be better off recirculating it back into the exhaust system than choking it up with a resonator

 

it's an interesting idea. If you can find one small enough I say go for it. I doubt you would lose much power. it should definitely smoothen the tone out as well.

 

uh, what? the whole point of an o2 dump is that it doesn't recirculate back into the exhaust system

 

My thought on this is it would choke off the exhaust being dumped before the turbo and likely cause boost creep

 

Idk if you guys are into MX or other forms of racing, but they are putting "power bombs" on the 250s and 450s. I wonder what that would do to the sound buy weldng one in with a short straight piece after it?

If you google it you will see what I mean, might not do anything, but changing the shape of the dump would seem to slow down the exhaust gases leaving the dump and should change the sound some what I would think.

 

Is this what you are talking about?:

Have it shoot out of your hood vent. The tone will change dramatically, haha.

If that is not an option, just go with recirculated. Something like a MAP true 3" O2/down pipe is ideal. You would probably get gains all around switching to one of those. In addition the flex coupler will help keep other parts from fatiguing.

 

Get ready for boost creep. If you don't like the noise, as mentioned before, I would recommend recirculating. Also make sure that the entrance into the DP is a small angle to avoid turbulent flow.

 

I think im gonna try this "power bomb" resonator...

 

Does anyone else think this not a good idea, to add a small 2.25-2.5 inch resonator to my Muse O2 dump?

 

I love the sound of my open waste gate, scares the **** out of some poeple.
