Wonder if he was thinking axelback? Seen catback for over 900

[Intimidator]

The prices I kept finding for the Cat-Back was from $850 to $1100 dollars. That's why I was happy with my cost!

I still didn't see the Outlaw on his site???

I also have a hard time believing that there are no HP gains from doing a "Free Flowing" 3" Cat-Back...just from all the resonators etc that are now gone and some of the crimps in the stock 2.5" exhaust piping!

In theory I think the same.X pipe replaces h and resonators,X allegedly worth 3-6 hp.One resonator has a big flat spot on the pipe, took it down to 2.13" in diameter. Head pipes each have a flat spot, back pipes mandrel but slightly crushed a bends?Stock mufflers perforated pipe inside and with packing that is not straight but a s bend.
All this worth what, 10 hp, 0 hp?
but they do sound better!

I just purchased my CAT-Back system yesterday. I used google to find the lowest price. Summit and Tenesee Speed both list at $772 and Jegs at $789. Neither Summit or Tenessee had a Military discout and Summit charged a handling fee. I spoke to Jegs on the phone and after discount and shipping the total was $709 to my door on Firday. Kay at Jegs was very helpful and to have it arrive so fast was a plus. Summit and Tenessee both had shipping dates that weren't until next week.

Very nice!
If you love and want the true Muscle Car sound of the 60's and don't have headers...this is the exhaust for you! If you enjoy a quieter Europeon sound then you will not like this system.
I can't speak for someone with headers but I would imagine this system would be a "Monster" and maybe too much for an everyday driver like mine!

Perfect. That is exactly the sound I am looking for. I probable will not be able to sleep tonight knowing that they are going to be delivered tomorrow. I will not be going with headers until the warranty runs out. Then I will get headers, hi-flows and a tune.

Question: You did say that you had the Outlaw Catback #817556 and not the Axle Back #817504... Right? I'm not really concerned about the 4 cylinder sound because I use the Range to disable it.

Also, how does it sound inside when cruising at 70-75 on the Highway in 8 cylinder mode? Absolute no drone at all? At this speed is the sound loud enough that you have to talk a little louder to a passenger to hold a conversation, or does it quiet down when not accelerating aggressively?

I've got a 2011 2SS/RS L99 Coupe... and Flowmaster Tech said the Axleback Outlaw Kit would probably be excessive, even with the factory L99 Resonator in tact? As a result, I'm concerned that the Outlaw Cat Back might be obnoxiously loud? Don't get me wrong, I want it to be really aggressive and have a nice deep tone; in fact, I don't care if it gets obnoxious when the pedal is to the floor! However, when driving conservatively, I want to be able to talk normally on the Camaro's Bluetooth System, enjoy a conversation inside of the vehicle with a passenger, or listen to the radio at about 15? Yet, even so, I want the exhaust note to indicate what's really under the hood... with that "it cant be stock sound"!!!

What about the idle... after the car reaches normal operating temperature, is the idle really loud? Do you have any sound clips posted anywhere that I might be able to listen to?

Correct me if i'm wrong, but it looks like the catback setup for the outlaw series will not fit on L99 with the ground effects package?

Based on what you've written (if you're wanting Outlaws) I'd recommend getting the axle back system. The cat back system will get loud. I have LTs and no cats; at 70-80mph it's loud in the cab. Now that I've added a cam, it's a little louder. I have drone, but the system sounds amazing. It's not too loud for me, but for a lot of people it would be. By keeping your stock 2.5" pipes and resonators you will eliminate a lot of the volume at cruising speeds, but when you put it to the floor it'll still sound like you want it to.

I don't see an Outlaw system that works with ground effects, however they do offer an American Thunder system for ground effects. It will have a similar tone to the Outlaws but they're just a little quieter. (if you're doing LTs and a cam, I'd recommend American Thunders!)

My Outlaw axle back came yesterday. Going on this weekend. Can't wait!!

[InfernoB]

I don't have the ground effects package Bro.... I'm just hoping that the Outlaw Axle Back will be agressive with my L99 resonator in tact and without headers, highfow cats… etc. All I'm doing is changing the axle back portion of the exhaust... I'm just kinda torn between the Axle Back Outlaw Kit & The Cat Back Outlaw Kit... worried that the stock L99 Pre Axle Back Configuration is gonna be too quiet?

No one said you had ground effects.

The best thing you can do to find your answer would be to listen to each system in person because what each person considers "loud & too loud" is a matter of opinion. If all you plan to do is exhaust, or exhaust and headers then the cat back (my opinion) would be ok. It'll have a little drone but it'll sound good. If you plan on removing the cats & adding a cam then I'd consider the axle-back. With my set up I plan to add high flow cats to quiet mine down a bit, and it that's not enough then I'll change to the American Thunder mufflers. (these two cat back systems share the same midpipes, so if you do get the cat back and you think it's too loud you can change it out for the American Thunder mufflers to quiet it down.)

Here's a couple clips of mine. I don't know if they'll help you at all though.

I have the flowmaster outlaw catback on my L99. It is everything I have hoped for. Loud when you get on it (and probably any other time if youre outside of the car) but not that loud in cabin. I drive people around all the time and we have no problem having a conversation. Cruising on the highway is not loud at all. Of course I don't have LT headers or a cam. The only thing I have is a CAI.

THIS. If you don't want it to be outlaw loud, do yourself a favor and get the American thunder catback. It is a little quieter than the outlaw, but still sounds great. In my opinion you should get rid of the L99 resonator. No matter what axle back you get with the resonator in place, it will just destroy the sound. If you put the same axle back on a stock LS3 and compared it to a stock L99 you would realize why the resonator needs to come off. Go with the American thunder catback if you want a little less aggression

[InfernoB]

@ agd5151... So you have only added the CAI and Outlaw Catback, with everything else otherwise stock; Right? Have you experienced the "annoying drone" that everyone seems to be worried about? Also, do you have your AFM tuned out? If not, is the 4 cylinder mode really that bad? I don't want an American Thunder Kit... For me, its either the Outlaw Catback or the Outlaw Axleback with everything in the Pre-Axle Back remaining stock. It's no doubt in my mind that the catback is gonna be louder than the axle-back; I'm just wondering if the Axle-back will be noticeably more aggressive than the stock mufflers?

I'd love to hear an Outlaw setup in person!!! Anyone in the Detroit Metropolitan Area with an Outlaw Catback or Outlaw Axleback on an Automatic L99???
