How does it sound? Thats gonna make some noise.

its actually not as loud as i figured it would be i have a video ill see if i can upload it

Procharged silverado - YouTube

turn the volume way up my phones been taking really quite videos for some reason think my speaker is blown out or something

Sounds good at idle, the question will be how it is at wide open with boost. Boost makes it louder.

probably loud as hell but thats cool with me truck isn't my DD only my weekend toy

It's prob going to sound almost identical to mine. How close is your top bend to the bottom of the bed ?

its probably inch away from the bed i got it as close as possible so i wouldn't have issues with the rearend hitting

I love the sound of my MBRP 4 inch exhaust system on my truck. Its quieter than my old magnaflow setup. Nice and mellow at idle but screams like nothing else at 6 grand! Love it!

I had a single 4" on my truck back when I was running the d1sc and I loved it.
