MAC cat back system any good??

[EVLHRSE]

I've got the MAC 1" 5/8 primay equal length headers, MAC X-Pipe and MAC 2 "1/2 Cat-Back. The car sounds AWESOME. The mufflers are tucked up nice for ground clearance and you can't even see them from behind the car. I've got wide 275 tires out back so the two piece tail pipe works perfect for adjustment purposes.
