most of the kits available are well built and straight forward to put together, just depends on your price point, I have helped with MBRP and Magnaflow and I say Magnaflow edges the MBRP in easy of assembly, but both are nice kits

I have just cut out my stock muffler and cat, and Im satisfied with the results, makes noise when I want it to, and no drone on the highway at 60-80mph

I see no harm in leaving your truck plugged in over night at all, the only thing it can hurt is your power bill, but its not at all a problem for plugging it in over night

 

thanks for the info, i have heard form several sites and that what difference does it make for backpressur with the cat, i was thinking about just doing a muffler delete

 

Back pressure is not an issue with diesels at all, the Cat just eats up airflow

with a diesel, the more air in, the more air out, the more fuel you can add, its a pretty simple equation

 

well im a diesel tech, but havent ever had to work on a duramax before, i work on powerstrokes and cummins engine almost everyday but havent worked on any duramaxes. i own a duramax and want to get better mpg but i want it be a little louder to as well. im most likly gonna do a 5" straight pipe turbo back but the main thing is cash.

 

Well My new exhaust is done. i put a Muffler delete kit on it and left the cat, (just to stay legal). I didnt want the truck to be loud, i just wanted better sound. now thats its done its not any louder but its got a mean growl.

 

it sounds so much better without the cat

 

ok no more cat exhaust straight piped mbrp 5inch turbo back

 

I am having trouble finding an A-pillar guage Pod i would like the double for boost and egt, and cannot find one anywhere around Harrisonville Mo, if so there really $$$
anyone have any ideas?

 

Autometer and Isspro make them i know, check with the vendors on this site, im sure they can hook you up, and it will probably be as cheap as you can get it locally

 

No cat no muffler 5 inch straight pipe
