Thoughts on all catbacks offered for the SS/TC
I was wondering something, and before the bashfest starts, I DID several searches, and came up with nothing.
A local has the magnaflow exhaust, frankly I didn't even think Magnaflow offered one because when I last looked in 2011, there was nothing listed.
I came across a thread here that cited after their R&D was done hp and torque gains were observed on a bone stock SS/TC, not big gains, but gains none the less.
I have always read that a catback doesn't do much other than sound different on a TC, but this guy's car is pretty mean, and it sounds like a jet fighter when he does a drive by...
So, are there any threads, or any sources which might cite which exhausts merit gains on a K04 car?
Thanks!

Well catback like you said is more for sound if you want the gains its all in the Downpipe. So if your looking for a catback you like just go to youtube im sure you will find alot of examples of how a tc catback sounds. Me personally liked the turboxs FL catback and thats the one I will be getting on moday

I have read time and again that an aftermarket exhaust will not yeild a single hp.
But Magnaflow has shown that even on the stock tune (c/w learndown), that gains are to be had on a 100% stock car with their exhaust - that's pretty hard to refute.
The above link <removed> will show both a 'take off' & 'drive by' video of the final product for our SS/TC. Magnaflow hasn't yet finished uploading
pics of the catback or the dyno graph, but I uploaded what was given to me.
<more content removed>
My experience with it so far: It's only slightly louder than stock, with no rasp or drone at highway speeds, with a gain of ~10 whp. Very,
very high quality fit & finish. Enjoy!
This local car, as I mentioned is pretty mean - and it sounds down right nasty...
I can't help but think that although gains might be small, that a better exhaust will yeild less restriction, and see some gain over the stock system;
Keep in mind that the stock system does crimp down to something like 2.25~2.5" at points.
Has absolutely no one here done any dyno or track visits to try to prove or disprove gains netted from an aftermarket exhuast?
One thing that befuddles me is that time and again people here seem to just believe something is so, because they read it here - almost like people take CSS.net posts as definative, and stop thinking... It seems odd to me, that on a car which responds so well to an aftermarket 3" downpipe (catted or not), that zero gains should be observed from a full 3" mandrel bent system.
I'm not trying to argue, I am trying to foster conversation that isn't purely of a dismissive nature.

I can tell you that I ran a zzp catless and their cat back. I noticed loss of low end and it was very loud. No muffler and no resonator. Sounded too bad to me so I took it off and put the stock cat back on.

I have a catless DP and full Hahn 3in exhaust with res and muffler. I love how it sounds it sounds deep but not too loud for daily driving I would recommend it to anybody for sure
