Yeah, bought setup used and it was for a 5.3.

 

You can't hear exhaust inside truck unless you are in it. It has a really clean note with no burble but a little rasp as you can hear. When driving I only hear it(the rasp) at 6200 when shifting.

Are the headers 1 3/4 or 1 7/8?

 

Justin recently did a lot of testing with 1 3/4 vs 1 7/8 headers on his 6.2. The difference was pretty substantial. For a truck the 1 3/4 are really the better fit. Low end was improved and mileage was much better. The gain with top end hp was quite impressive with the 1 7/8, but would rarely ever be utilized in a daily driven situation.

Mine are 1 7/8" and I don't doubt those findings at all. If I had no other plans for this truck I would have went with 1 3/4". I know I gained torque over the stock exhaust so I'm more than happy.

 

I can't believe how much of a difference it made actually, went from a shit and get truck that laid rubber down, to blowin the tires off at will anywhere under 20mph. You actually have to drive it now if you want to get it from a dig. I need to figure out how to start driving like an adult again but what's the fun in that? :)

Kooks are on... I'll tune it tonight and report back with a sound clip. I'm actually modifying the Y-pipe now because it was for a 5.3 so I'm dragging out the 309 wire and upgrading the output side of the Y-pipe to 3.5", or 4"... We'll see what I have room for.

What Plug wires did you put on there? I have the Pacesetters and have a few of the stock wires that are too close for me.

Wires probably don't need the protectors because they have the 135* boot which gives them tons of room and they have a thermal barrier built in which is what makes them a 10.4mm wire. I absolutely hate burnt wires so it's worth it to me for the extra protection.

Here's headers, ORY, and Corsa touring.

 

It sounds mean under wot, but I plan on sticking a magnaflow resonator on it to deepen the tone. If that doesn't work I'll get a new muffler.

What header bolts did you use?

They came with the headers, look like a chrome set from Local auto parts store but you certainly don't need em. There is tons of room for bolt heads.

This is current setup, too loud for daily driving. I appreciate everyone giving me their advice, I think I'm going to stick with the Corsa and install a Vibrant Ultra Quiet Resonator, for its seems to be the good route thats also good on my budget. Anyone have stories about Vibrant Resonators?

Not a fan of anything Vibrant makes. I do some fabrication as a hobby and have used Vibrant products a few times and can honestly say their quality is all over the place and the materials seem very cheap. I will not and have never used Vibrant on any of my personal stuff. I have used it if someone supplied the parts.

 

If I were you I would pull the Corsa and install a different catback. It really is a shame corsa doesn't produce a "touring" system for these new trucks like they did on the older platforms. I have had corsa on many cars and the new 2K trucks are the only thing I have heard that they sound like a race boat when you add headers.

 

A friend of mine has a 14 Denali and his truck was the fabrication mule for ARH and he also got one of Corsa's first kits and it was insane how loud it was...and not in a good way. His intermediate pipes DID have the ARH cats.

 

This is from my TBSS... 1.875 Stainless works headers and ORY. Corsa Touring.

Holy crap that's loud! I listened to it through my truck stereo, don't advise it.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
