Hi all,

Looking to make my Z28 much louder and have been looking at FlowMaster Super 10s as that the loudest they make and I have read good things about them + various videos on the sound etc

Question is Are there any other comparable mufflers from other manufacturers in terms of noise level , i.e their loudest? If you could be specific that would be great e.g. magnaflow xyz

It currently has a very large Magnaflow muffler (I will try to find the specs/measure it when I can) which is ok but not loud enough and I have been trying to see what magnaflows answer to the Super 10 is not no luck.

Does anyone have experience with a very aggressive muffler on a stock LS1, mine is totally stock except the muffler and tips.

Thanks

You can look up sound clips.

Could you fit an slp loudmouth resonator on it? They are pretty loud on the catback.

MagnaFlow 14159 - MagnaFlow Stainless Steel Race Series Mufflers these are commonly used very aggressive mufflers used. Of course they are not compatible with having factory style dual tips and usually just have a dump tip by rear axle. They sound really good with factory manifolds/cats but get very very loud with LT/ORY. SLP loudmouth is what people go for if they want a whole catback with very aggressive sound.

Thanks guys,

I checked the paperwork and I have the Magnaflow 16723 kit, with a 5" x 8" Oval Muffler Offset In/Dual Out: 3" /2.5" Body Length: 18" Overall Length: 24" Core Size: 2.5" Polished Finish https://www.jegs.com/i/Magnaflow/642/16723/10002/-1

They describe this as moderate in sound so that makes sense at least as its nice but not loud.

Definately leaning towards the FlowMaster Super 10s with 2 outlets, 3 inch inlet and twin 2.5 inch outlets to match piping and then only abit of extra piping would be needed.

Thanks guys

I would suggest any of the 40 series mufflers if you want more sound but wont be obnoxious. 10's might be a bit much for average person.

I don't know what your sound laws are like, but Series 10 Flowmasters are usually too loud to be legal in most places, even with cats in the system.
