X & H pipe vs straight dual exhaust

famous bob said
:blob:once upon a time , I bought the complete drivetrain out of a 68 hemi roadrunner, had 11,000 some on it when it rolled. it had a factory h pipe on it. don` figure it was for low end torque, cause the hemi had more than u could use back then anyway-----just sayin-bob

I can't confirm it, but it makes sense...I heard H-pipes were used on production cars because X pipes created bigger clearance and maintenance issues on the car overall. So they compromised with an H.
