Duramax Diesel Exhaust Mods, and Stuff*

[geektoad]

Sooo... how ya liking it??

It's amazeballs. why on earth did i wait this long to do it, etc etc etc.

it really drives like a whole new truck. can't wait to work it and see how it does.

How do you like the sound?

It's great...with the cat still on and the muffler it's super mellow until you hit WOT...which seems to be happening a lot the last couple days

Agreed. Our trucks should sound nearly identical, I imagine. My guys at work give me a hard time, because mine is so quiet compared to their raspy straight piped trucks. I hate the sound of a Dmax with a 5 inch straight pipe and no cat

Yeah, That sound is just not my bag, and it's not just that i'm getting older and don't like loud...it just sounds like shit.

The wife and I went out in it last night and she likes where it's at now too, so double score!

Alright, you two... I have read some on the Camaro forums about the TCM's being locked to a particular VIN (and, in the Camaro's case, being un-tuneable without being unlocked).

I had "thought" about buying a spare TCM for tuning the transmission. But, if I can't flip back to the stock TCM and have it work without needing to "re-authorize it" or whatever, what would be the point?

Not sure. This truck isn't leaving my possession for a very very long time, so i didn't even look into stuff like using alternate computers for tuning, etc. I'm not sure what the deal with the VIN lock is. It might just be that they need the specific key for your TCM to be able to put the tune on. *if* that's the case, there shouldn't be any reason you can't have the stock one set aside and a tuned one in it.

That makes sense. But, I wasn't sure.

Since I've already had the Camaro in the shop to have the torque converter replaced, I'm a little apprehensive about doing anything to the tune that they could later detect, point a finger at, and go "A-HA!! YOU f'd it up!"

Where are your exhaust pics??

I forgot to ask, where did you chop your OEM pipe?

 

[geektoad]

I chopped it on the flat after the DPF, but then still couldn't get the back half out over the axle, so i cut it again after the axle. I couldn't be bothered to see if there was a different way to get it out. fuggit. Might have been able to get it out if i didn't already have bags in, but i'm not sure.

Didn't take many other pics while doing the install as i was running out to work on it a bit at a time during a work day (yay working from home) but here are a couple from today:

I'm probably going to take it over to my bud's shop at some point and weld it up. band clamps aren't bad on a Camaro that's 4 inches off the ground...they stick the hell out on my truck though.

Also...vroom vroom.

Awesome. Yes, as soon as I find a shop that will weld with stainless wire or TIG I will get mine done. I may just drive the 8 hours to Eugene and have the shop that built my awesome exhaust on the 09 do it.

I hacked mine at the back, just in case I have to reinstall it
