07 NBS 5.3 now with aerochamber
 

got the muffler put on today. I will get some video up this weekend. I like it so far. It's pretty quiet, till you let it rip :devil: Hopefully it get's louder after I get some miles on it. it's pretty entertaining when it drops to V4 mode, lol. I can tell everytime now, lol.

I'll be ordering my 5/7 drop next week. can't wait.


GOD I LOVE THIS TRUCK !!!!!

Soundclip!!!!!!!!!!!

+1

I gotta hear the 8-4 shift for myself! :devil:

i guess i could charge up the camera tonight so it will be ready to go. I'll see if the camera can pick up the V4 mode. It makes me laugh every time it does it. fuck it. I'll do that one for you right now, be back in a minute.

Cool!

uploading to photobucket right now

ok. the quality is not the greatest. you have to listen very close. the sound is hard to hear. maybe turn up the volume. It's a complete octave change. wait till i get below 70 and turn on the cruise control the second time.

hey dont worry about that v4 mode after a tune it never works again...lol

Any fuel mileage numbers in V4 mode on the highway without those WOT accelerations?

Hope you had better luck than I did with this muffler. I ran Aerochamber on my 2006 w/4.8 and dump over the axle and it sounded great. I did the same thing on this truck and when the truck would go into 4cyl mode at 60-70 it sounded like a diesel truck. I couldnt stand the resonance, so I had to add resonator in front of muffler. Now she sounds alot better but you can still hear the truck go into 4cyl mode if you listen for it. Guess I am getting too old. :)
