Hey guys, I was wondering what would be a good exhaust set up with cats still intact with a nice tone? Not interested in some river high pitch riced sound. My previous Fc was a 86 and I didn't what was on it but it had a nice and low tone to it. Looked like stock but it wasn't

 

From my experience on piston engines, the bigger and longer your resonator/glasspack was the more high frequency sound was absorbed.

Having said that though, I've read that rotaries will tear through convention glasspacks in a matter of minutes due to the high heat and strong pulses.
A lot of people have suggested the racing beat per-silencer....

There was also a thread of somebody making his own out of perforated steel and high temperature fiberglass iirc.

 

Try checking out SR Motor Sports.

Good luck.

Coarse steel wool was the material used.

Cheers!

 

look into magnaflow or basani mufflers.

 

Thanks you all!

Plastic: yea I was reading up on it cause I had a fc previously. Cherrybomb and yes some of the modern stuff can't handle the heat from the rotaries. Got to be specific

Sm3: yea I was thinking about looking at those two but havent found any YouTube clips of either on a fc

 

Custom all the way!!

Some people may disagree with me, but I love the sound of the HKS Superdragger. I had the same setup on my DSM and it sounded great.

 

I having the racing beat dual exhaust and the sound is very additive, and also because it's a rx7

 

RB all the way!

 

I have the Apexi. It has a good sound

 

also have an apexi and it has a nice sound
