Well it doesn't seem like I'm gonna find an Rs-r Exmag, so now im looking at other posibilities. Anybody know of a good alternative? I know the Ws2 is similiar since its quiet, but does it produce the same power? Need your guys' opinions. Want something not too loud, preferably quiet, and nice deep throaty sound. Thanks.

 

Neither exhaust is going to uncork a massive amount of horespower.
The WS2 will work fine, unless you've got plans for a 450hp turbo B-series.

 

Whats the size of the inlet piping to the muffler? Because I want to run 2.5 inch piping?

 

60mm throughout, which works out to 2.36".

And like the RSR, the rear muffler on the WSII is a chambered muffler.

Is forced induction part of your overall build plan?

 

very few mass produced exhausts are 2.5''. most if not all of the japanese companies make their exhausts in 60mm.

 

No forced induction. I'm planning on staying NA. So u guys think the ws2 is a good choice to go with my jdm itr header or any other suggestions....

 

ITR muffler.

 

Anything better free flowing than the itr muffler?

 

its not gonna be a huge difference.. mufflers are usually just to quiet sound.

 

Yeah, pretty much everything besides a chambered muffler design.
