I understand all that but at 450hp your not going to use on the street as a daily driver.

LOL sez you! Ha ha ha ha. I have and will again right soon.

No, you really don't need 3 inch pipeing for the street. Since I still don't know how much power your engine is making, I'll make a blanket statment with a grain of salt for understanding and a rubber band for lee-way.

2-1/2 inch pipeing is fine and enuff for most street machines on the road today.
