Are there any HP gains from the muffler delete?

I've had the Magnaflow axle-back muffler delete on my SS (LS3) for a few months. I did the install myself. Pretty simple. Unbolt after the cats, sawzawl at the appropriate lengths, bolt on the straight pipes, and button everything back up. I went with the Magnaflow due to the awesome looking 5" tips. Much more aggressive. Love the decel popping.

Just did my 2012 L99 with Doug Thorley muffler deletes. They were 1/2 the price of any others I could find. Had one problem with the install, the flared ends were not wide enough to fit over the cut ends of the stock pipes. I had to take them to a muffler shop to have them flared wider. Sounds great now and I do not notice any drone. The AFM just sounds a little louder now when it kicks in. Here's a link to the video:
After driving some more, the AFM is most noticeable (annoying sounding) at slower speeds, like 20-30MPH. Last edited by GarySS; 12-20-2013 at 05:58 PM. Reason: adding some info |

I have a 10' SS M6. Heads, cam, headers, no cats stock diameter with stock h pipe. is there any way to cut the exhaust off before it ever makes it to the rear end of the car?? I was thinking about welding in a couple dynamax bullets or something similar. surely someone has tried to run a shorter setup?

It may not add any power but it cuts about 20lbs off the car. And this car needs a diet

That's one of my main concerns is the weight. I've got my exhaust out right now while upgrades are being done and can't help but think I could modify the exhaust and keep it under the car. I've looked and looked for pics of one and have yet to see one that has been done. Mine is not a dd so I'm not worried about cabin noise and so on.

The muffler delete sounds pretty damn good. I am in the market to upgrade my sound a bit. I have been looking at a couple cat back systems (Corsa Xtreme & Borla Atak). However, if I went this route it would save me a pretty penny.
Have to look into this more. Who knows it could save some money for some other mods I would like to do, in particular with the suspension. Hmmm, looks like I may have issues with a muffler delete in VA. Grumbles.

the only issue that rears it's head is drone...and since I did my rear gear upgrade the car seems to spend more of it's time around the 1800-2200 range where the drone exists...not bad in the summer with the windows down and the radio playin...now in the winter it's startin to wear a bit...gonna do some j-pipes soon...good luck.
btw - why would a muff delete be a prob is VA? noise? the way I look at it diesel p/u's have louder exhausts than my car does(until about 5k or so heh heh) and I don't get any second looks from popo...now emissions and cats are a diff story...is your car tuned? dynoSteve at RDP set me up and I have zero cel, can pass any emissions and get 20+ mpg hwy...give him a shout.

§ 46.2-1047. Muffler cutout, etc., illegal.Seeing that the Cats would still be on there, emissions should be fine. So guess technically it isn't a straight exhaust. I would think that means pipe straight from the headers to the back. So not sure exactly what way I will go. I have read of people having issues and then tons of people that don't. With all the ricers with the fart cans on them around here I should be ok. Would be interesting to see how things would go when it is inspection time. Though, nothing on the checklist should fail it and if there were issues, be easy to swap em back on and off. Nice thing with that, I would be able to easily store the mufflers as opposed to a whole cat back system. Like to keep in case I end upgrading in the future. Though, pretty certain I would stick with mine instead of a Gen 6. Still think ours look the best. Just love that LT1. Then there is this law. Which seems very vague and I am not sure what defines excessive noise. § 46.2-1049. Exhaust system in good working order.
