I have the racing beat dual tip right now & sometimes it seams a little loud when cruising on the highway. If I put the stock cat-back on, would I lose a lot of power? Right now I'm using a restrictor plate for added back pressure....isn't the stock cat-back more restrictive, therefore probably sufficient?

 

I would think you would lose a little power, not a lot.

 

I'd say swap out your midpipe for a resonated midpipe from RX7store, it would probably make it a lot quieter (with no loss of power) than switching cat-backs (especially the RB duals). Besides, the RB duals are beautiful.

 

yeah if a strait through midpipe pipes to loud for u go with a resinating one.

 

The noise is coming from the midpipe. Yes, you could change the cat-back, but putting in a cat or at least a resonated midpipe will be better overall.

clean, relatively quiet, low pressure drop, awesome build quality....the best of all worlds

I will post pics within a couple of weeks

 

I already have the resonated midpipe (just updated my sig). Don't wanna sound like a wuss, but sometimes I just wonder if the car would sound a little "classier" with the stock cat back on it.

 

the stock cat back is horribly restrictive....but hey, whatever floats your boat
