mufflers: SLP vs Flowmaster; your opinions

[Judge]

everyone, i want to hear your opinions on these mufflers only.

What sounds better to you?

SLP Loudmouth II or Flowmaster Outlaw

[MaRoFreK]

Flowmasters FTW!!!

[Judge]

mmm interesting...

and why do you think flowmasters "F" the world? :p

[MaRoFreK]

FTW = For The Win. LOL. . I had a Stainless works Catback on my car at first then this week I decided to put Flowmaster Single Chamber mufflers on it and I like them much better. I also got to hear The outlaw series on a camaro in person and I really liked those also. I've not heard the SLP LM2 mufflers on a Camaro in person but from the videos I have watched they're a bit quiet for me.

all said flow master wins in quality and fit, and to last

I have no personal experience with slp loudmouth 2. I have heard it on a couple 4th gens and I am not all that impressed. I personally love the sound of my flowmaster outlaws with arh headers and catless x-pipe.

I have the Borla Catback, but after much thought i think im going to purchase the Flowmaster Catback Outlaw

You see guys...I think the LM II lacks tone

its loud, but quieter than the original loudmouth,

what i see in the outlaw, is that it has "the muscle car sound"

I had the Loudmouth I on my '02 Firehawk along with the SLP LT's, larger SLP y-pipe and high flow cats for about 6 years and loved it at the time. It was pretty loud particularly at WOT and start up, and it did get louder with age, so the car wasn't as much fun to drive anymore since it seemed to attract the attention of the law whenever I drove it.

A few years ago I pulled the LM I off and switched to the SLP PowerFlow exhaust and thought it was perfect. Not nearly as loud as the LM I but it did have a nice deep muscular sound to it and there was no drone or rasp.

I haven't heard the PowerFlow on a new Camaro yet, but you might want to look into that as well.........I'm sure there are some sound clips around here.

I had LM2s on my L99, and after installing them it left me wanting more. The more is Flowmaster. American Muscle, American sound! done right! and they are dirt cheap!

I had Loudmouth 2 axle back when I got my car. It had the SLP ZL 427 package on it and came with it. I loved the sound and would of kept it but I put a supercharger on my car and put cat backs on. I would go with the Loudmouth 2. Good luck man.

I have SLP LM2 on my 2SS its loud enough I already have to grab two gears when passing the cops dont think i need anything louder at low RPM at high RPM there very loud! If flowmasters are louder I would get a ticket for sure were i live!
