I also have the magnaflow catback system on my 2006 SS and I LOVE it. I am particular on how I like my V8 cars to sound and have spent plenty of $$ in the past on dozens of different systems on different cars (Camaros, T/A, GTO, Mustang), and this is by far one of the best sounding systems I've heard on an otherwise stock vehicle.
4cyl mode does not sound like a 4cyl, but somehow gets even deeper(?)...My favorite sound is at the mid-upper RPM range. It sounds insane for a bone stock 5.3l V8 in a front wheel drive car. Sounds a bit like a high revving big block...sort of

I like to Live and Learn the Hard way,
When I did my flomaster exhaust, I did it for sound, Now that I drag race more, wish I did a Full Cat Back,
So yea when I could afford it I would purchase the Magnaflow full cat,
Its all nice and shiny too
I should stop modding and just through in the 5.3 v8, One day when my car needs a new engine lol hopefully not too soon
There will be a 10hp gain with a full cat back
the difference is we are running 2.25inch pipes to our mufflers when the full cat is 2.50inches to the mufflers for more air flow out, meaning more Horse Power
Thats the main reason to do it and I hear it will help by a tenth of a sec or two of drag times

Any dyno sheets for before and after certain mods, such as the Magnaflow kit and the K&N intake? I'm curious.

Nice. I wonder if that was a supercharged one or a newer LS4 one. Probably Supercharged since the URL has "02Product" in it.
