Before you get flamed,, One pipe is sufficient. Your nott going to gain any HP to speak (3-5) of in an exhaust system. Only thing for sure you'll gain is lighter weight.
So if you put two pipes on the car what would that do? Add weight.
Stick with a proven Cat-Back Exhaust system. And there is a "Sticky" on the very subject.

The ass of the car looks just fine with a single 3" HKS exhaust...

single tip exhaust looks odd when the rear bumper has two exhaust openings. If we had an alternative bumper, then a single sided might not look so odd.

id go with single...although both look soooo sexy, IMHO the single side HKS looks DAMN GOOD, and the sound is SOO sexy....

To me the HKS single tip looks like a coffee can bolted onto the exhaust. You can clearly SEE the two bolts that hold it on. The Ti tip also changes color over time, so it doesn't have the nice clean uniform look to it. At least it didn't for me after a month of usage.

yeah with a different rear bumper a single would prob look good in my opinion

an "exhaust system" will get you 15+whp. note that an "exhaust system" is header+midpipe+catback. wording is slightly important here.

a catback only might net you 3-5whp.

the real difference is:

single weighs less. looks retarded.

dual weighs more. looks good.

Ouch kersh...this car should have never come with dual tips. The single tip always looked sexy on the RX7, Mazda should have kept it the same.

1st Gen RX-7 looked good with a single..

2nd gen looked good with a dual

3rd gen looked good with a single

Now the RX-8 looks good with the dual. I think they are playing mind games.

^That would be a combo of transmission temps and the exhaust.

Dual exhaust FTW! as for the cup holder being so dam hot, now that I have no cat I can tell my cup holder is no longer a cup warmer lol

and i fully understand that. but since there are 2 openings, it looks silly with a pipe in one and one empty.

if mazda had designed the rx8 as a single, i'd have no problem with it. or if someone put a body kit on the car that was single only, i'd have no problem with it. but having openings for 2 tips and only 1 tip... that just looks weird.

(btw, the body kit i'll eventually get, buddy club, would not look stupid with only 1 tip. i believe its the only rx8 kit that does this.)

if the single tip came out the rotor in the rear, i'd have been all for that. then lose the plastic and smooth out the rear... but haven't seen a body kit/ exhaust combo that does that.

I've been thinking about this a lot too. Dual or Single. I'm too vain to go single and I always think two holes are much more fun.
Even Mr. Norris would agree.

HKS does, however, give me the chills when I hear it.

both arent going to give you shit for power and cost you money so pick whichever you like better.
