X pipe H pipe or side by side

I love these threads You see who has comon sense. Look at the firing orders. Really!!. This is what determines the effectiveness of the pulse scavenge. On Mopar's and Chevy's with firing orders 18436572 X pipes are useless.

Some just will never agree because they were talked into buying that expensive heavy useless system that they are proud of looking at.

Did anyone ever think why only 440 HP and Hemi's came with an H pipe. 383 and 340's did not.

Cheaper to equalize the system then to increase exhaust and tail pipe size for the big cupic inch motors.

The sound of these cars were totally different with the H pipe . owned both at same time when new. 69 393 RR and a 69 440 R/T.

Just look at them both and try and use some sense X , H and don't give me that scavenge theory I don't buy it on Mopar firing order
