it is noticable if you are listening for it or under full throttle. I don't notice it to much and can still use my bluetooth. my apr mirrors make more noise thn the exhaust for most part For me.

 

Dual wall rolled edge 4" polished stainless steel.

 

FI, please sell me
why do i want to spend the extra$ for the one that Vik has (the full stainless?) vs the aluminum (the standard?) what does the top end model have that the low end does not?
i'm sure that most people here do not mind paying for value..

 

The full stainless doesn't have that blue tint right whereas the aluminum does? I like the exhaust but I don't like the blue tips since I have a platinum graphite color with wheat interior. I am going more for the silver, grey, chrome color scheme.

 

yes, this is what i want to know. what is the differences between the two?

 

No that blue tint is on Titanium exhaust. Or exhaust with Ti tips riveted on. a stanless or alum exhaust will not have that

 

+1 Id love to know. Also sell us on the inbetween model too? details details details

 

The group buy officially starts tomorrow but this might clarify a few things...

Sounds very nice! Nice video!
I think I'm sold. I guess I will let you know tomorrow!!


Edit: Can you post the Dyno's? Cant really see them in the video.....

 

The dyno chart will be posted tomorrow within the group buy...

Thanks, Tony

 

Can i get a high res copy of hte video? also, can i get the f ull videos? ive never really driven tht hard with the braking.

 

Since they are working on my G35, I'll post what I've learned.

Aluminized is steel tubing that is coated with baked on ceramic silver paint after it is bent into shape.

Stainless steel is the middle option that uses T-304 stainless steel tubing. No coating is needed since the SS tubing will not rust.

Finally, they have the polished stainless steel tubing which is the high end option. It is the SS tubing above except polished to a mirror finish like the mufflers and tips.



.

 

so, what is the bad thing about getting the aluminized one? will it rust?

 

You mean that wasnt you driving your car?
They did that without you ?

 

First, the components (mufflers and tips) are the same with all three choices, so the difference is in the tubing used.

I don't think aluminized is necessarily "bad". Keep in mind almost all production exhausts (like the stock one) are steel and do not use any coating. Aluminized steel is still steel with a coating. I guess if you manage to remove the coating, the steel substrate is exposed and can possibly oxidize. But if you manage to do that much damage to the bottom of the car, you have other things to worry about because most of the exaust is really tucked up tight under the car. You can see pictures of their exhaust using aluminized tubing on here:

Stainless steel has the advantage of little or no chance of oxidation, of course depending on the alloy used. Stainless steel alloys with lower iron content will oxidize less. Even if you damage the tubing, there is less change of rust. Personally, I would go this route if you plan to keep the car for a long time and/or you live in snow country.

Finally, the polished SS is obviously SS, but with a polished finish for aesthetics (if you wanna show off the bottom of your car?).

One detail that I would ask is what is the thickness of aluminized steel tubing vs. the SS tubing used. IIRC, the aluminized tubing is slightly thicker (FI will have to verify this). The thicker tubing will provide for a quieter exhaust. IMO, I would neglect the minor weight difference unless every pound counts, but remember this is a street car.
