It'll sound super awesome and sweet for a few days then get old lol.

Straight piped 5.3 always sounds great at idle though.

Awesome sound, but I think the loudness will get old. But a loud ls4 will age sooooo much better than a loud 3800.

Sounds good.


It's all fun and games until you drive the car on a road trip or somewhere similar then s**t gets real.

Dam that's loud!

LOL what no rev?

I'll do a rev video tomorrow

How's the drone? lol.. I kept the resonator in mine.

I'm actually thinking about putting something where the resonator was. The drone is not bad, the the pop from the exhaust from high revs down is what I could do without

rev rev rev waiting

idk when i do my exhaust i want to go with headers, res and nice borla mufflers ( i just cant seem to enjoy the 5.3 as much without any mufflers)

Even with the total of 3 cherry bombs on mine it still crackles and pops but that's cause our pcms lean out on decel causing that. So unless you tune out the portion you'll always get that noise from high rpm coastdowns.

Rev video as requested now up...
