Any ideas or thoughts on cutting the resonator out of the stock exhaust system on my 09 6.2L 4x4 chevy. Just wondering what it would do to the sound (HOPEFULLY NOT MUCH EXTRA DRONE). Cant see buying a new cat back or muffler when there probably wouldnt be much real hp gain and the factory system seems to have a descent tone already, unless someone has had good luck with any other configs. with this set up

 

any feedback would be appreciated. thanks

I cut mine off about 2" behind the resonator. On multiple occassions people have asked me what exhaust system im running and are surprised to find out that its stock.

 

The sound inside the cab hasn't changed, but outside it sounds deeper and rumbles nicer. Do it! :confused:

When you say behind the resonator do you mean that you left it on and just cut out the tailpipe section. Or if it was cut in front 2" between resonator and muffler it would exit right below the bed between the framerails. Is this OK.

 

Thanks for the input

If you have a video camera do a before and after shot of the resonator...idle rev and takeoff so we can all hear the difference.

Resonators make the exhaust quieter and help reduce drone. In some systems they can also help with raspiness and might actually sound better with it in place. But if you want it louder, that would certainly be the first place to start. If you don't like it or end up with drone, just put it back on. Good luck!

Yeah i guess I said that kind of backwards. I cut the exhaust pipe between the resonator and the muffler, about 2" of the resonator.

On these 6.2L trucks, all the resonator does does is quiet it down some... no raspiness/popping/etc and no drone in the cab with it cut off. And the exhaust is nowhere near "loud" either. It's just a deeper more notable tone than stock.

 

I would imagine that if you cut the exhaust pipe closer to the muffler than I did so that it was exiting closer to the cab then you might get some more drone. My exhaust exits above the rear axle.

do you have any kind of vibrations or anything with the "tailpipe" exiting so close to the underside of the bed like that , guess if i didnt like that i could have a shop bend or install the right pipe to bring it out like factory

 

 

thanks for your help

no vibrations or anything. When I cut the resonator off I angled the cut so that the exhaust flow would be directed downwards. There's also an exhaust hanger right there supporting the pipe so it's held firmly in place.

The stock exhaust sounds REALLY good on the 6.2's out the rear. I can only imagine that cutting off the resonator would make it better. :D

Yeah, It already sounds awesome. I'd like to get a little more aggressive tone out of it. I priced the Corsa Sport muffler at $375. I figure I'll cut off the resonator to see if it gives me the tone I want. If not, I'll just buy the Corsa Sport muffler and have it welded on.

Matt, It's been a while, have you noticed any issues with the resonator being cut off?

 

No issues at all. I'll probably NEVER look into an aftermarket exhaust system for this truck, its perfect with the resonator cut off :D

That was my logic too. I figured it would either not change it enough... or i wouldn't like the sound; in which case I'd just get an aftermarket system like I was originally planning on getting.

 

Glad i cut the resonator off first before spending the money on a Corsa :happysad:

Very glad I found this thread. Been looking around town and all over the net trying to get ideas about what to do for the exhaust and this sound like a great place to start. I had a couple shops amazed that it had 3.5" tubing stock, heck half said they didn't have a pipe bender big enough to handle that.

 

 

Anyone have a sound clip of just the resonator off?? or maybe even one with a performance muffler installed? I am up at work for another week so can't dive into this with my truck quite yet..

i have the 6.2 with a flowmaster muffler on it that sounds good but still has the resonator still on it, does anyone know how it would sound with a flow and no resonator? would it be too loud?

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ).    I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.
