Question for the masses....for a car that's gonna be running close to or just over 500hp (N2O or blower + some other goodies in near-distant future

) - would you recommend short tube or long tube headers? 1 1/5" or 1 3/4"? 2 1/2" of 3" exhaust? Is it true that longtubes will take away some low end torque? Should I stick w/ my BBK 1 5/8" equal lengths shorties and just work back? Sorry for all the ?'s
