Question About Cat Back & Axle Back Exhaust Systems
- Is the resonator removed in cat back exhaust systems?
- Are mufflers the only parts that are changed in axle back systems? Nothing happens to the resonator in the axle back systems, right? |
well i am not 100% sure on this..... i think on axle back system you mainly just are changing the muffler, but you do replace piping that goes beyond the muffler.
the cat back i believe you replace all of the piping that goes all the way to the front bumper... i really dont know much but that my guess..... sorry ...lol |

I think on the cat back systems, you change everything after the catalytic converter. Now what's the difference between the complete cat back systems and the custom cat back systems? What happens to the resonators? Here's a pic of the stock exhaust system (I think, not sure if it's completely stock)... http://i822.photobucket.com/albums/z...camaro_ind.jpg And here's what I think... http://i822.photobucket.com/albums/z..._camaro_-1.jpg |

yes....cat back replaces EVERYTHING from cats back. axle backs replace mufflers to tips.

SamSS described it pretty good. I think some aftermarket cat-back systems still have a resonator. I seem to remember maybe Corsa having resonators. Mine doesn't.

That is a stock LS3 system. |
SS LS3 vs L99 stock exhaust comparison
Whao, whao, whao, wait a minute here.
I thought all the SS exhaust systems were the same! Now these pics really make me question the need for a cat back system on an LS3! The posted pics from samSS show no main resonator under the heat shield and practically straight pipes to the stock mufflers. The H pipe looks completely wrong from a flow characteristics point of view, an X pipe would work better. I guess the real sound killer are the mufflers. Anyone know what the smaller resonators look like on the inside? Are the exhaust systems different between the two models?? Having seen this side by side comparison makes me think that all that is needed for the LS3 to roar is to delete/replace the mufflers. Am I wrong, or is buying a $1000+ cat back system for the LS3 a waste of money?? Tom |
Thats what the LS3 exhaust looks like I've seen under a 2## LS3. I'm putting an axle back (Borla Stinger) on my 2SS LS3 when it comes in. But I prefer to keep the H pipe. But I would sure like to know what those resonators look like inside also. So I can decide whether or not to have them cut out (don't mind some drone if I do). I"ve seen a post of what they look like on the L99 from a post on here. Would someone replacing there exhaust on a LS3 PLEASE cut one of the resonators off and post a picture of what it looks like through it as far as flow and sound adsorbance. Thanks

I dont think this is because flowmaster is better then corsa I think it is because at around stock HP levels the stock LS3 piping from the cats to the rear mufflers flows just as well as the aftermarket cat backs. I belive the best way to go unless you wanted to pump out some serious HP would be just to get an axle back (if you have a M6). The sucky thing is corsa doesnt offer just a axle back. All this is of course based on the 2 pics that were posted above. If they are not the standard M6 and A6 exhaust then just forget everything I just said.:sm0: |
Okay... A cat back system replaces everything from the cats back to the tips eliminating the resonator and replacing it with either a true X-Pipe or a muffler with a X-Pipe inside of it. Some makers such as Magnaflow offer two set ups. The above described called the street series or, one called the competition series which is the same but with no mufflers before the tips. The axle backs replace the pipe from basically the axles back to the tips. Again, some with mufflers and some without.
