5” Straight Pipe On LB7 Duramax Sounds AWESOME! 🚂 

I love how the epa goes after our diesels, but completely ignores all the private jets and airlines that put out more pollution in one year than every car or truck in the us does combined

Exhaust came out good. Glad you were able to make it work. That exhaust expander kit will come handy. Now all your freinds will need to use it.

I have an lb7 and trust me get a turbo horn and cold air hsp does make the turbo horn and ur spool sound will be very noticeably different

Dream truck right there. I have a 2003 lb7 duramax now. But there is only around 20-30 dually's in my country. A lot of regular silverado's but dually's are rare

in stead of dealing with the carrier bearing go with the Dmax store aluminum driveshaft conversion. i did it to mine and it’s the best

The 4” was already swedged to go over 4”. All you had to do was cut that last 5 inches of pipe off and the peace would have slid over it instead of in it. But good job on figuring it out and getting it done 💯🤘🏾

I’d spend the money on an HD cowl hood instead of the older cateye style grill

Just go to your local muffler shop they’ll bend 4 inch exhaust to your spec. Easy fix

Finally ! This truck is all we care about !

I like the way it sounds that sounds good as Hell

A welder woulda done the trick too and quicker 😂

just put a 5" on my l5p and fit perfect and sounds good

Do you have a link for the exhaust?

Sounds good. Thought your paint looked really good u til you said something lol.

What oil and filter do you use in that truck?

I hope you'll be able to wrap the truck to

Do you have to delete tune a lly duramax?

Dream truck

Epa needs to go after all people with cats deleted on cars

Have you replaced a cp3 on 01-07 max . About to go in and do it , didn’t know if u had any tips if you have ?

hey do ya stell have the 5 inch muffler?

I want to trade my 7.3 for a lb7. But I’m scared 😅
