I am on my second set of axle back mufflers on '07 GT. First set was SSS Stainless. Second set are Flowmasters. Both sets had a good outside sound, but the inside drone is terrible. Does anyone know for sure of mufflers with a desent sound without the inside drone ? I was told both sets I have put on would be no drone. My car is auto trans. Would that cause more drone ? I'm about to the point of putting my stock mufflers back on. If anyone could help me I would appreicate it.

 

Many chambered systems will have some drone with the exception of the GTAs. From what I have read, Corsas tend to have zero drone. I have MAC Boom Tubes which is a straight through design like the SLP LM system, the difference is in the louvered core, which is like a race muffler. I don't experience any major drone in any of the rev ranges that I operate in. At highway cruising, there is just a hum that is barely intrusive at all.

 

My KR mufflers have nearly none inside drone.

 

turn the overdrive off when you hear that drone??

 

I have the Steeda axle back and I don't notice any excessive drone ...

 

there is a little on the Borlas (non-stinger) but its really not that bad unless you're in fourth gear going 30mph and try and floor it.

 

I have had a few different setups in the 9 months that I have owned my car:

Stock
Pypes muffler delete
Pypes offroad X/Pypes muffler delete (WHOA)
Pypes offroad X/Stock Mufflers

The muffler delete was too glasspack or truck sounding for me, and with no cats holy crap it would literally wake the dead. I had that combo for a week and got rid of the mufflers.

I am VERY happy with the OR/X and stock mufflers, they are pretty quiet when you are just driving but when you hammer it they really come alive. The only real criticism that I see is that it might be slightly raspy for some people. I have heard people really like an O/R H pipe with Stock mufflers. Again, to each their own..

 

Corsas are probably ur best bet..

 

Corsa's are the best for sound as well as ZERO drone.
You can bank on it!

Corsas = 0 Drone.

 

I'm not trying to be a dick but come on ... How can you say that? I have the Magnaflow catback with a offroad x pipe and have zero drone but you say the muffler deletes don't have drone? I've had them and they do drone.

Stingers sound great, but they have some drone. Personally, I like the drone--but it doesn't look like the threadstarter does.

 

Pypes mid muffler for sound but they have minor drone, a lot less that the stingers..

 

+1 on the KRs. Excellent sound at WOT, no drone and very nice cruising at highway speeds.

 

If you hate drone, stick with the stock mufflers. The GTAs and Corsas are drone-free based on TMS member feedback, but honestly the stock mufflers are fine for me. I had Pypes Violators and I couldn't stand the drone.

 

Borla 11752 are nice..for me. Get loud when going up hill in 5th at 1500 or so but not ear splitting.

I like 'em.

 

This discussion is.. interesting.

How do you determine what's an awesome muffler for your car without trying it on for yourself? (That one is rather self explanatory, so I don't really need an answer for it, but hey, go for it if you must.)

Corollary, but much more important... how can you *pay* for all those different possibles, if you keep not finding the ones that are perfect for you?

Muffler shopping has got to be *the* worst situation I can come up with, unless you just get plain lucky and smack 'perfect' upside the head right off with your first choice. How many can say that?

/I guess I might be one... those Thrush CVXs I used for my dual set up on Muskrat were pretty **** sweet, but I didn't buy them for the sound, I bought them for the 'not gonna rust... ever' thought process.

Spent a bunch of time looking and listening, online and in the meatworld as well. That is really the only way to go, like a lot of mods, it is an individual thing for everyone.

Ended up with Magnaflows and couldn't be happier. Just a little deeper most of the time but you know when you romp on it. Even got compliments for a coworker with a GTO with Flow 40's on it.

 

Go to a show etc. and see for yourself. I wanted 304 stainless if spending that much.

Heard youtube clips. Heard, for real, Stingers, GTA's, Flows, etc. Rode in a few cars, blah, blah blah.

My choices were Corsa and Borla 11752 since my kids have sensitive ears. Not a peep out of them with the Borlas..they say the car sounds "cool."

Corsa, while awesome sounding, a little too many $$$ for me now.
