@@rodleypumpkins4174 your videos are really good, had a 02 duramax rebuilt with a few mods. Trans will not hold out forever. Suncoast does build a great trans. I think im going to have whittys diesel do mine. Im also adding the 6th gear. Im going to have them lock up the convertor in 4th 5th and 6th. By the way, just your opinion on HP ratings. Im running a 50 over block, 64 mm turbo, studded heads, 100 hp injectors, 100 hp fuel air dog, 4 inch stainless off road racing exhaus, bank air rram system. EFI Live performed by Industrial Injection systems and racing. The trucks like a 9700lb rocket. What would be yoyr opinion on the HP. Wouldnt hold ya 2 it

Guys, I have to comment here…. I just did this upgrade on my 2006 LBZ and it was a huge pain in the ass. I decided to replace the rubber chassis mounts for this project and taking advantage of lifting the body off the frame for greater access. But the issue was the transmission dip stick mount to the bell housing on the transmission. For me, the only solution was installing a spacer against the housing on the studs and then using fender washers and another nut to clamp that fork into position. That extra 1/4” of space made it work for us. My friend and I are both engineers, so it was not a lack of experience that caused this. At one point, I called PPE and talked to their tech support to see if others had encountered this. Their reply was, “Its mild steel, bend it”. But, there are several bends and nothing would work. Our solution was the only one that worked and it’s fine now, but I submit that there’s a lot of info not being presented on these videos. Just wanted to share this in case this helps others. On a plus note, the performance upgrade is noticeable. I get faster throttle response with “less pedal”. My MPG has increased a bit as well.

[@shirecain2129]

I just bought an LLY 11/7/18. First diesel ever. Watched plenty of yours and other vids before purchase. Ended up with a banks 4" full exhaust, banks ram air kit, banks six gun and a AFE air inlet. $9k 253××× miles. Oh and brand spankin new tires too. Wouldn't have known what to look for without you. Thank you

[@CHICOB4261]

I did it! I installed the MBRP down pipe on my LLY 2005 Duramax diet today! Took about 4 hours but I did it! Thanks for the assist brother!

[@bptraveler6608]

Just finished installing one from PPE. Just a hint to others, I removed the turbo shield by removing the bolts, holding it up off the turbo and cutting it in half front to back with a sawsall. It was easy to get out and I could reinstall it. Thanks for you video it was a great help, as usual.

[@jeffscheule9067]

If anybody sees this, it is the difference between having a headache and making things easy. Unbolt the passenger side body bolts, there’s at least two, mine had 3+ the one extra under the headlight. Raise the body off the frame about an inch and a half on the passenger side only and the job is as easy as can be. The exhaust will fall out, the turbo heat shield will come right off without having to cut it. If one person sees this it was worth posting

[@mmazurenko]

Followed your steps exactly today on my LLY. Went flawlessly. Thanks for the great video.

[@TruckMaster]

+Michael Mazurenko perfect! Glad I could help

[@paulgreenlee190]

My 2007 GMC 2500 Classic LBZ came shipped without a Turbo Heat Shield. I bought one off eBay for Around $60.00, I used my Metabo with a .045 cutting wheel and cut it in half, using 1 bolt hole on the passenger side and 2 bolt holes on the Drivers side. Put the larger section on the driver's side first then the smaller piece last. Took about 10 minutes and I feel better about the fuel lines and wiring harness being protected from the heat. I'm not telling you to take it off or on, the correct way of taking it off and on is to raise the truck cab off the frame at least 6 inches. If you are working at home there is no way to do this so just cut it in half for easy removal and installation. It was designed for a purpose is all I'm saying. I'm a subscriber to this channel and enjoy the videos even the few I don't agree with Truck Master does a great job explaining and installing.

[@tb3687]

Feel blessed your not doing this on an LB7. 3rd night attempting this. Finally got the dipstick bolts out. Turbo heat shield was the easiest. Had to cut the bracket that is above the lower band clamp. Today I finally got the last bolt out of the middle of the long heat shield to remove it. All that is the same between the trucks, however, I have 12 point bolts going all around the turbo that now have to come out compared to one band clamp. 2004 LB7 330+K miles Great channel by the way!

[@_N4VE_]

lol i bent the shit out of it and wiggled it out. I also dismounted the glow plug controller for extra room which helped a ton.

[@trukintimmerduramax946]

word of advice, I'm doing this on my truck now and i haven't deleted the EGR yet. There's not much room to get the heat shields off with EGR intact, delete EGR before tackling the down pipe. Your bloody hands will thank you! I'm not going to be able to pull shield up thru like TM did going to see if i can pull it down thru today. If i get the middle bolt on shield off.

[@noahjohnson7342]

A word of advice for anyone doing this job, if your doing it on an LMM duramax you’ll have to cut off the top heat shield and do not try to take the downpipe heatshield out through the bottom. It will save you hours

Damn big difference on the sound !!

I'm getting ready to start on this and the up pipe tomorrow after I finish wrapping up my y bridge install

[@JN-mk2fh]

Great video. My experience was slightly different. The worst part was the heat shield on the turbo. A huge pain. Had to slice off the driver's side section of the heat shield to access the V-band clamp. I also had to remove my trans dipstick completely in order to get the stock down pipe out. Took about two inches off the bottom of it to refit it back into the trans. All in all, this is a huge pain of a job but I really like the smoother, lower toned exhaust sound, and it doesn't screech. Supposed to lower EGT as well. My lower mounting bracket on the aftermarket down pipe did not want to line up.

[@TruckMaster]

+J N what a nightmare! I’m glad you got it done though

[@drod459]

Mannnn I just loveeee the duramax whistle from the turbo

[@TruckMaster]

+drod459 me too it never gets old

[@larrybeaudry5096]

later next month came earlier than expected on my down pipe and exhaust install..so I dug into it this weekend..It went pretty smooth except for a few things I hope will help others. When you remove the turbo heat shield..its makes it a lot easier if you remove the glow-plug module and the bracket..then bend the heat shield in the middle to make it into a shape of a(M) then you can slide it out where the glow plug module was. I was able to put it back in place then bend it back as close as original form..( I was only able to get 2 of the 3 screws back in) but before you do all that...I would loosen the lower bracket support that holds the down pipe to the exhaust manifold and confirm that the original one is not cracked..(mine was broken in 3 pieces) and they are known to brake They are tack welded onto the exhaust manifold next to each bolt. I removed one bolt at a time and chiseled the broken pieces off. The bracket is available at dealer if you buy the new down pipe(what a joke) but at ProFab PerformanceProduct Code: lly-lmmdpsupport The reason why I say to check this first is..you cannot install this bracket unless the down pipe is out of the way.. So my project is on hold until it gets delivered.. Also when you re-clamp the top clamp on the turbo..move the nut to 10 o'clock so you can remove it easier if you ever have to ..the heat shield can be pushed back against the firewall and you have access to the nut.I hope this helps someone..

At 9:30 that a/c condescension drip tube in video, I just bought an LBZ and the heater core was thought to be leaking by seller and me, but found out it was that lil 90 deg tube turned up and backing up the water so bad it was leaking on vinyl floor and mixing with some orangish Texas dirt! Haha it looked like dex cool at first I thought oh no heater cause of the intense labor involved with replacing a heater core in these 99 up trucks. Lucky me it was just the tube got turned up.

The lly and lbz have a v band clamp and make it much easier but the lb7 has the mounting bolts to the turbo and the bottom one is such a pain to get to and have enough leverage to break it lose.
