Flowmaster for 88 sub

[Hobbs]

I have a 7.4 3/4 ton 88 sub and I want to add a flowmaster cat. back exhaust.

When I spec out my truck on varies web sites I get a system that matches everything about my truck except the engine size. They say it fits a 5.7L and makes no mention of 7.4L. Is there a difference between the 5.7 and 7.4 from the cat. back that I should worry about?

Attached example.

Thanks,
Hobbs

If the system fits your truck it will work, if its a 3" exhaust it doesn't matter unless you are running over 300 hp
