Pypes exhaust system sound 1.MPG

Here is the Pypes SGF70 system installed on my 79 Firebird.
The engine is a 301ci, the exhaust manifold are stock there are Pypes downpipes, the Pypes sgf70 crossflow system, and the Pypes short straight tailpipes.

Hi, your firebird sounds great! Did you have to make the downpipes for yours? I purchased the Pypes SGF11S crossmember-back system. Trying to find the downpipes for my 301 also. Just talked to a Pypes customer service guy and he said they don't make any downpipes for the 301. Jegs website lied to me and said these Pypes DGA13S would work 😭 . But he said they won't.
