Alright guys I need some help. I'm running twin 67mm turbos, so I need an exhaust that will work for what I'm doing. To be honest in my case, no exhaust is probably better, but I need to have one for driving around town.

Options:

1. Dual 3 inch to single 4 inch back to dual 3 inch
2. Dual 3 inch all the way
3. Dual 3 inch to single 4inch, single exit

Any help would be appreciated. I'm leaning towards number 1, but wanted to get some insight of what some of you guys that have experience in this department would do.

Horsepower goal is 1300rwhp+, to give you an idea of what type of power the exhaust needs to handle.

Thanks in advance.

What would you prefer, if all setups were equal in "flow?"
