can someone give me some stats on dual exhaust from 1 header. is there any HP there or is it just look

 

its just for looks, because their is not enough back pressure with dual exhausts and you will lose power.

 

yup, its about flow velocity... backpressure is not good for exhaust flow

 

The only thing its good for is Turbo.

 

what if you stepped down the piping size where it splits? would that increase or decrease the velocity??

 

I was considering the dual pipes from the muffler. With the mufler mounted sideways and one pipe to each side directly from it. there is a single pipe from cat to muffler. I know that flowmaster makes an application like this for V6 camaro's

 

The only car this is gonna be useful for is the Camaro. All it's going to do for your car is add weight and mess with the exhaust flow as mentioned above. Just throw a good cat-back on and call it a day........

 

fair enough
