I lie to myself a lot.... I put a GMPP cat back on it today along with a leftover Denali cluster, got an intake tube in the mail, and weather permitting I'm putting on the left over shackles from the GMC on it. Here's some pics and sound clips.

Gotta be worth a couple of pounds:


Before sound clip- bone stock 5.3 flex fuel.


After, GMPP "Performance" cat-back. Sound on my camera kinda sucks, it's pretty quiet and has a really deep tone. I'm pretty happy with it.

 

how much is that catback exhaust? i dont really hear a huge difference.

 

I picked it up for just under $400, it's not very loud, but it does sound a lot better. I think my camera just sucks.

 

well might as well complete it with a custom tune!

is that muffler a straight thru design?
