2 Tips or 4, THAT is the question...
Ok, so pretend for a minute, that looks didn't matter... Are you with me yet? 
Stick with me here...
In theory, dual tips should yield more in the performance department due to faster exhaust speeds, right? There would also be a slight improvement in the torque department and possible reduction in theoretical top speed due to the reduced exhaust capacity of the two exhaust tips.
Quad tips, although looking very cool, may decrease the efficiency of the exhaust system caused by the lower pressure (slower exhaust speed) at the end of the system.
I am very tempted to go for the dual tip system by Zoomers. They offer a lifetime warranty, and Ron is a very cool, very knowledgeable, very helpful guy. I also think the exposed Venturi Extraction Tip is kinda techy and unique. Below is a link to Ron's site:

When I spoke to Ron today he said that they had protyped a quad setup and should be in production soon. But in the end, it might just be dualies for me.
What do you think?

At the end of the day however, a dual or quad catback system yields minimal power increases over the factory system. The choice primarily comes down to sound and looks.
Bullets and Corsas seem to be very popular 'round here.

Bullets and Corsas do seem to be popular on this site. I fear the dreaded "drone" that seems to be an accepted part of those systems. I mean no disrespect to those that have them; I have just read many of your comments and the drone seems to be a common theme.

Drone is common on many systems. Some systems however intentionally seek to eliminate the drone - the Corsa's for example. IMHO - they sound terrific and somehow manage to completely eliminate any drone. I went with 4-tip Corsa Touring, which are definitely a less aggressive tone than the Bullets or Corsa Sports... but they do offer a terrific rumble down low yet are quiet enough (and completely drone-free) at speeds - you can carry on a conversation just as easily as if you had the stock exhaust. Some (most) prefer a louder exhaust, so you'll see the Sports and Bullets prevail on this forum.
It's really just a matter of personal preference.

Creeper, you and I seem to like the same things... 
A little rasp and base but still refined.
Have you been around the Zoomers? There is just something unique about them. The Corsa Tourers were the other ones that I have been considering. No drone, you say?

I got the dual tip Zoomers system and I really like how it looks. If you are leaning toward the Zoomers, go for it! You wont regret it. If you want it a little louder, get it w/o the front resonators like I did. It gives the system more "attitude" without being obnoxious.

Here's a vid of my car when I got the Corsa Touring installed.

I love my Zoomers, there is a little drone at 1500 RPM but I call it music. I talked to Dave at Zoomers the other day about the quad tips and he said there is no difference in sound. I like the idea of the quad's and am planning on having them installed on my system.

Creeper, great vid! They sound AWESOME!!! And those quad 4inchers, YIKES!!! They look like cannons - very cool look.
Vet4les, let's talk about that drone... Do you have any vid with sound?

Performance gains from a cat-back exhaust system are negligible at best. I couldn't imagine dual or quad tips making any practical difference other than appearance...go with the look you like.
I preferred the 4 - 4" tips.....

What do you think? You're kidding, right? Wow this is a new one. The amount of tips do not make a difference. You could have 8 on there and you wouldn't notice any decrease in performance, because there wouldn't be any. I prefer the quad tip because it fills out the port nicely and matches the quad tail lights. Almost zero power gains from a catback on a stock motor. Regardless of the amount of tips.

Well, actually, no I wasn't kidding...
I am new to auto performance but very well acquainted with cycle performance where small tweaks such as the ones I asked about can change the character of a bike hugely ie. a liter twin with a single vs. dual exhaust. With bikes, and cars too, I assume, torque rules the land and a little back pressure and a slight squeeze post-can causes accelerated gas exchange and "Walla" increased usable performance.

Torque does rule the land. But the fact of the matter is that by the time the exhaust gasses reach the tips, the mufflers even in most cases, they've lost all velocity and offer no performance gains or restrictions. So just go for whatever system looks and sounds the best to you.

Thank you. That is completely different from the motorcycle world, and for good reason I suppose. Is this because of the distance between the valves and the point of exit? It could also be because of variances in the diameter of the exhaust throughout its travels causing inefficient/inconsistant travel speeds. In the end, it doesn't really matter how you feel on the inside... It's what you look like on the outside!
