I've got the N1 dual. Fun sound with plenty of backfiring with a 3 inch midpipe.

Border Burnout. Haven't heard it yet, but rumor has it, its very very loud.

 

JIC something...it's been awhile (4+ years) since I've owned it. With a Borla midpipe it sounded awesome. That's my all time favorite. 2nd Favorite is of course the Border burnout 90mm.

 

I vote for the RB duals, have them on my car and know of 2 other local guys with them on their cars. Another local guy has the PFS exhaust but after hearing the RB duals he fell in love and wants to get the RB exhaust. Like everyone else said the RB duals have a great deep purring sound in the low end and a nice roar while getting on the throttle.

has anyone ever tried to run duals on the 3rd gen like they do on the second gen.....like to 2 2 1/2" clean a simple mufflers...maybe two 3 1/2" single or dual tip...small can size kinda angled like on the 300zx...

 

ive never seen duals on an rx7 but wouldnt think the results would be very good... i had the hks hiper on my 90' 300zx and hated the look, it was cheap, flowed well, but looked too overdone for me, now i have some original trust TR exhaust complete with resonated midpipes..



as for the best 3rd gen exhaust i would go with the rb, or possibly the newer RSR exmag, the rsr is suposedly one of the quietest(which doesnt say much for an rx7) and looks very nice. I have the hks hiper on mine with straight 3 in midpipe and just like the z im sick of it, too race looking for a street car, too loud. ill prob end up with the rb or rsr. You can get plenty of power from a quieter exhaust without all the noise. just look at the 2005 911 turbo. Which i now have hehe... (by the way, the rx7 is still faster!) rx7

 

I am partial to the FEED, I had the SONIC HS-R for my FC, since then I have sold my FC and bought the FD. I am currently running the SONIC SR, but I maybe be selling it soon and upgrading to the SONIC Ti. The best way to describe the exhaust is it real simialr to the HKS, Apex (anything with a 5" tip) but has more mid tones since the tip is 4". From what my friends tell me that it sounds great at cruise and WOT etc, but I am always in the car, and it never sounds the same being in the car as beening a bystandard.



Here are a few pics I had.

 

Can't really run true duals unless you get rid of the stock fuel tank.

 

well you can y around the tank....i have a full 4" exhaust on mine with the greddy muffler...down pipe and all...you can take a base ball and roll it all the way through my exhaust...and whats wierd is its quite until the external wastegate opens.....then its really loud! Everyone trips out how quite it is...you would think it would be loud...
