Im looking at the racing beat exhaust system and i would like to go with the true dual exhaust, but it does weight more. Does anyone know any specs of the hp gain / weight savings for the true dual compared to the single pipe exhaust for an N/A exhaust system?

 

I don't know exact numbers, but true duals will give you more hp than collected exhaust. If you are concerned about weight, there are other places to take it out, plus the weight of the exhaust is below the roll center of the car, which is better than above it.
I have dual exhaust on my car, and I have definatly noticed a difference, especially on track. Low end is greatly improved, and the car pulls stronger through the rpm range. I would definatly reccomend it.

 

True duals are best for stock port car. If you ever plan on getting a streetport or more, go with collected.

But true duals sound 10x better

 

The question is...
Can you really take advantage of the weight difference?
