Great comparison guys

The white one was most definitely running a hotter tune. Should’ve ran a similar tune to make it fair.

I totally agree with you on that. The reason I ran a hotter tune is so the truck spools up faster. But it sounds about the same in stock tune!

My 2008 GMC Sierra has 5 inch straight pipe and it sounds great, and my 2014 Chevy Silverado has 4 inch straight pipe and it also sounds great, I just love Duramax's in general when they are deleted and tuned😂

I have a ‘07.5 Sierra tuned and deleted with 4” and have been considering converting to 5”. I think it has a deeper tone. I also have a ‘11 Silverado tuned and deleted, that has 968,xxx miles on it.

I've got a 4" on my 05 LLY cateye with a small straight through muffler/resonator back to 4" sounds really good little deeper note then straight 4" but not as loud as 5". Its a work pickup so I hate the drone at highway speeds. You guys should add the small muffler to the 4" it will sound a lot better afterwards

Good to know, picking up a CCSB LBZ this weekend with a 4" straight. We'll see how much different it is from my LB7 with 4" and muffler.

Can you post the link where you bought it please ?? The 5 inch

I got a 4” with a 5” tip. Sounds good

Both systems sound good for sure!

Hard one to call, both sound great! I have an LBZ and thinking of building a custom exhaust, but really not sure, 4" or 5" and what muffler and where? I tow heavy so don't want too much drone

Was the white truck was purchased in Winchester, Virginia?

This is the video I was looking for a few months ago when I was deciding on the 4 or 5 I went with the 4 because of me hauling equipment and I didn't was it screaming at me the whole time.

After running the 4" for a year would you go with 4" again or would you go with 5"? I do a lot of hauling to and I'm trying to decide if I want 4" or 5". I also wonder will 4" keep slightly more back pressure for more boost?

If you live in Michigan and want to get your Duramax tuned and deleted, take it to GreatLakes-Motorsports, they will make them things run wild. My 08' has a stage 1 tow tune and I got it to 135 with ease, my 14' has a stage 2 and got that to 145 with ease as well
