The FCs comes stock with Dual Exhaust, but I've seen a bunch of them that have single exhausts. I want to upgrade my exhaust eventually, and I was wondering if it made a difference (performance wise) if you have a dual exhaust or a single exhaust?

 

I Love my single exhaust. RB Header to RB Presilencer to Corksport Catback. But DAMN it is loud!

 

hahaha, no silencer?

 

If you plan anything more than regular city driving then drop the silencer, it's bad for the engine.

Different exhaut styles are mainly for personnal tastes and sound control.

 

I sorta figured, but I wasnt sure. I'm think of goin single. I wanna get a catback with a nice deep throaty sound. Any suggestions?

 

I did the racing beat true duals and I love it I would buy it again but I would not buy the presilencer

 

Rotaries tend to have a very high pitched (and LOUD) sound. Racing Beat is probably the only company making an exhaust that sounds deepish and with a decent sound level. Single will yield more peak power but also increase dBs. If you just want an exhaust with a nice tone then go with Racing Beat (dual though).

 

Yeah I checked that out. I liked how it sounds. I'm considering it...

 

Turbo or NA? The RB REV TII exhaust does a very good job of keeping the noise down. Keeps the car looking stockish so you get more of a sleeper look. If thats what your aiming for then RB is the exhaust for you. If you want a massive fart cannon to buzz around town with then look elsewhere.

 

All about the RB REV TII .. but then again I'm partial. Nice deep sound, lots of power, and looks great. Sorry for picture whoring but here you go

 

i prefer the duals because they have a quieter tone... but I wanna straight pipe my duals to make it so just oh so beefy.... just depends on your preference and price ranges

 

I had APEX'i Dual N1s before. Loved the look and the sound was decent hum until WOT turned it into a ferocious roar. I've also had the Motoria single, but it didn't really satisfy my tatses the way the N1 duals did. 6/half dozen.

 

i had the rb road race system and i loved it, i now have the rb revII system on my turbo car and still love it. i kinda think singles look goofy cause there is 2 cut-outs in the bumber.. so use them lol

 

^^ a lil bit of bondo and a good hour can fix that :p

So any single tip setup that is quite-ish?

 

It's NA ('88 GTU)

 

I was looking at the Apexi GT Spec Cat Back Exhaust. I found a video of one, but not on an FC or even a mazda. But it didnt sound too bad (deep sorta quiet), would it be similar on an FC?

 

Those cats ending at the end, look a little low dont you think?

Id go with the racing beat rev tii, and throw on a racing beat header. Im not sure how this sounds together but i would imagine amazing.

 

a few days ago i looked at a 88 accord with an Apix N1 catback kit and it had a nice deep sound to it(lol a honda) so im assuming it would make the rx7 deepish?

 

the sound a car makes with its exhaust is not determined solely by the muffler or cat-back system.

if all any car has is a cat-back system, yes it will sound deep and throaty; of course to the extent of the particular engines noise characteristics.

if you out a full exhaust on ie; headers, pre-silencer, silencer, resonator, mufflers

then the actual engine note will not change due to a muffler. more than likely if you have a very free flowing exhaust, you will get the engines natural sound; which in a rotary, is a high-pitched, metal rattling sound, no matter what muffler you got on it. because after all that, your muffler is just slightly doing its job(muffling)
