I been reading up alot on aluminum exhaust piping. I am building a car for a customer right now and he is telling me he wants to run an Aluminum exhaust. I am not asking about the life span of aluminum or anything. I really dont care abotu that. What I am more concerned with is flow. I hear alot of mixed decisions of the flow chracteristics of aluminum vs stainless.. what are your thoughts on this?

 

I dont see how the flow can be any different if all else is equal?

 

x2, only thing i can think is the smoothness / roughness of the inner piping, I guess this would have a minor affect in the way gases escape.

 

aluminum does have a tinnier sound (raspy) but should flow the same

I know, I test and digest just like this. RMF off me.

titanium

 

Don't we have to think about heat and the transfer rates of the different metals?
