Need To Drop Decibels! Exhaust Question

[FLUID]

Hey, I've got a r33 na with an x-force cannon (4 1/2 inch) and want to get it quieter with less vibration that hurts your head after a while. I've installed the silencer and that's done alot but want to hear any ideas of fiberglass, cotton etc inside the cannon to get some quietness. Thanks

try getting a better quality muffler (such as an oval shaped muffler), and look at getting a middle muffler put in.

A Varex muffler would help, they are one of the best sound deadening mufflers I have found so far, and then you can close the flap to silence them if you need to. My 3.5 inch one doesn't drone much at all.

How did you set up the boost actuated Varex???

One thing to note about the Varex, I think they are illegal and cops can defect you on it.

Yea they are illegal and can be defected for them. Is the rest of the exhaust std? Or is it a cat back?

Does anyone in here have a car that can't be defected? At the end of the day the goal is to not be pulled over, the impression of a stock car is the key imo.

Unfortunately there are no aftermarket mufflers I can recommend to reduce noise to a legal level other than the closed Varex. Other than that you would be best off finding a S/H jap cat back with a Jasma label.

I have gone back to the Varex motor on mine as the varex valve was too tight and kept jamming. There are other options I am trying at the moment.

Exactly, I think even my FMIC can defected can't it, just don't fail the dick head test if you do get pulled over.

The boost controlled varex looks interesting, shame it didn't quite work, and am interesting in hearing what you come up with.

Apexi also had an exhaust with that built in, I just can't find it on nengun

there are plenty. any exhaust shop could sell you about 10 different ones that would, but few people would want them on their imports as a: they aren't fully hektic cannons, and b: they aren't a straight through type (so don't flow as well). but even a decent flowing muffler used with a decent centre muffler will give you exhaust levels below the legal limit. a non performance orientated muffler will be built in the same way as a stock one and give the same level of noise attenuation

With a 3.5 inch system? You have to be kidding... Most of my customers want 300kw at least these days, with two free flowing mufflers. There aren't many on the market that cater for low noise along with the flow, especially in stainless.

Yeah well if you want a 3.5" system then you have to accept that you won't get an exhaust as quiet as a stock 2.5" system. That's pretty obvious.
