I recently purchased the MagnaFlow cat back exhaust. The seller also threw in a 3" high flow cat.
I recently read that the stock LT1 cats flow very well and little performance gain is to be had by replacing them. True?
Aside from performance, do you think the high flow cat will make a sound difference/sound improvement with the MagnaFlow?
My goal is to have the exhaust sound great and loud but at the same time have little resonance and drone inside the car...
I can't wait to get the new exhaust on.
