5.3 swap headers

[75K5]

What have all you 5.3 swappers used for exhaust manifolds? I don't really want to notch the frame if I don't have to. Do corvette manifolds fit? If not, any aftermarket headers?

Thanks,
Brian

Vett manifolds will clear but I ended up just going with the truck ones cause they dump at the rear and the vett manifolds are more of a center dump.

Thanks for the info. Were you able to use the stock Catalytic converters and downpipe?

Thanks,

No the stock cats and down pipes won't clear the frame on the drivers side I did use the stock collectors for the o2 bungs but I had to cut and rotate them to clear different things. Also I am using the old th350 so I had to drop the down pipe under the shift linkage.
