Exhaust quietting recommendations? 2011 Camaro SS - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Texamaro · 09-19-2020, 03:49 AM

Hi all! Im looking for some recommendations on quietting my car down a bit and hopefully eliminating some of the drone going down the highway.
It's a 2011 Camaro SS, cammed, tuned (all that good stuff). Currently has long tube headers, cat deletes and magnaflow dual center exhaust system (not sure model).
Prior to the cat delete and long tube headers, but with MagnaFlow, I loved how it sounded. Now I barely want to start my car after 9pm for neighbors sake.
Any tried and proven recommendations to keep my set up but add on something to mellow the sound a bit?.
On a bit if a budget but would like a permanent solution.
Someone mentioned adding a bullet?
Thanks in advance!

Put the cats back on.

You can either put in some hi flo cats, which will be a good move in the long run if you are in an emission testing county.

The only other thing is to add mufflers. Magnaflow makes a great muffler, many call it a resonated x pipe. It's just a dual in dual out muffler with an xpipe in the center of it. I had one of these on my '96 Corvette that had no cats and no mufflers. I had no drone or resonance what so ever. Also did it to my otherwise stock 2011 SS Camaro.

For a cammed car with headers, maybe a combination of a true x-pipe with mufflers might work the best to get rid of that drone.

Have J pipes installed by someone that knows what they are doing.

^^^^ This as mentioned above. I had this issue before and installed a Magnaflow resonated x-pipe, did the trick for me, no more drone and a bit quieter too. Then I finally was able to do a complete 3 inch catback system, now I'm getting ready to order a new Corsa catback system.
Here is the resonated x-pipe.

You could always find a stock cat back on the cheap.

Good lord man, did someone lift the car up with the trans pan? Mine caved in a bit when I had the jack under the pan during my engine swap and that was from just resting on it. I swapped in a new OEM pan for $25 or so. I got nervous because the trans filter/pickup feet rest against the bottom of the pan and I was worried about any fluid issues.

SlingShot · 09-19-2020, 08:47 PM

I'd go back with the OEM cans on it. They actually sound pretty darn good with headers, remind me of Hush Thrush mufflers.

Can you install exhaust cutout's? I have them on my SS and I love them. I get tired of the drone and the engine popping sound when I decelerate. I want it loud I open the cutouts, want it quiet I just close them.

SSJ2 · 09-19-2020, 11:52 PM

J pipes took care of all the unbearable drone on mine. I currently have long tubes with hi flo cats straight pipes and muffler deletes

lemontwist · 09-20-2020, 07:30 PM

off topic but for the love of god don't put another fram oil filter on that car.

Texamaro · 09-26-2020, 06:46 PM

Sorry for the delayed reply guys been out of state with my dad who's currently fighting cancer and I got super side tracked.
Thanks all for the suggestions! Still going through options but need to order something asap.
Also as an FYI for the above comments I got the car with the beat up trans pan and Fram oil filter. Both have been replaced. Lol..
