or do the square ones.. i mean the back end of the car is so boxy

haha

 

The rear is my least fav part....

 

The quad reminds me of the M3, but it's still amazing! Imagine the afterfire with that. lol

 

4" Round, but I think all three are great options.

 

Due to the popularity, I'm sure they'll sell a single exit, dual 4", and Quads.

 

you guys should post a pic of the car with the different exhausts on the ground and further back so you can get a complete idea.

 

have you guys thought about doing a production exhuast where you could pick the tip you want? cuz i like the last two.. you know?

 

^Why not just do one side the 4" and the other side the Quad?

Originality FTW!

 

I like the look of dual 4" best, preferably with a very slight angle. However, I would base my design upon the following factors that are much more important to me:
- which makes the most power
- which one weighs the least

 

^Good points.

What makes most power.

How the hell do each of the sound.

 

I like the oval and the quads.

When will something be available for purchase? I want to put an exhaust on the car pretty quick but the other stuff people are coming up with looks like something I would have had on my Civic when I was 16. These look nice and keep the car clean.

 

tough decision. All the designs look great, but I think the quads would end up sounding the best. And oh yea, do that heating thing to them to make them blue that would be sweet. The larger circle is in japan like you said (example below) but now imagine the quad tips with the blue rim like this! SEXY!

 

Quads are silly enough on a strait 6....

 

I agree the oval or the quads are the best. The X looks much more refined and clean compared to the 8/9. I think the dual 4" looks way to ricer for a 4cyl... if you want a 4" do a single exhaust. The others look cleaner and more grown up..

Again I think the main thing that matters is the least amount of weight/most free flowing for more power. Sound is also a factor.

 

+1 billion

This design along with the heated Ti treatment tips would be the next hawtness!!!
