Anyone here has this battery in an A6 2.7T? My current battery weight is 40LBS and this one is only 15lbs so 25 lbs less. I know it is not a lot but I was thinking if the battery works without any issues why not get rid of those extra pounds front the heavy nose. this is the battery i am about to get http://www.tirerack.com/accessories/detail.jsp?ID=31

As a note, I paid 1k for an APR exhaust and I dont think I gained any power but I know I felt a difference after the installation and was wondering if that difference was the weight savings from removing the heavy stock exhaust and installing the APR one.

 

It will make the car really really fast... 0.0000000000001 second faster!

 

If for the street -- NO!

If your concerned about weight it might be better if you go on a diet.

 

So the exhaust. I see people feel better buying a $500-$1200 exhaust for zero gains and going really really fast.. 0.0000000000001 second faster

 

This is my main concern. Have you ever have one of these? what issues did you have for street-daily driving?


Weight is not a concern however it would be nice if the A6 was lighter. Im 5.8 at 140lbs at 11% body fat.

 

Exhaust is bit different than a battery change. Personally, I wouldn't get an aftermarkety exhaust on my car unless I went with a larger turbo kit or serious internal upgrade. Then it actually will make quite a difference. Although a properly designed exhaust system, such as an APR kit, will give you a few more horses for a stock car, it is usually for the noise factor. Is it worth it? Hey whatever floats your boat!

As for the battery, I have to admit that a dry cell battery, such as Optima is better than a wet cell. Yes it is lighter, more durable and is not affected by angle and acceleration. But for a daily driving car, I am sure whether there is a significant benefit.

 

Light weight racing batteries are not designed for the street. They are ruggard but usually good for only about a year and do not do well in cold weather.

The optima is a bit different - it is a good battery with tons of power, but from my experience they have limited life-- not 5 years like many high end standard street batteries
