Magnaflow Cat-back? Hey all, I read that flowmaster is a garbage cat-back because it's not stainless steel therefore doesn't flow good like SLP LM or GMMG Cat Backs. but what about Magnaflow Cat-backs? I have a wicked deal on getting a Magnaflow Cat-back or should I just stay with the Flowmaster I already have installed?
cheers!
cheers!
Stainless Steel is always better, But to be honest they all offer about the same HP. Other than the slowmaster. 
I personally like the SLP, MagnaFlow, GMMG, Corsa, Borla, Mac (not SS), And of course "What I have on my car" - Hooker (Not SS though)
Just stay away from the Flowmaster. And if you want to improve power quite a bit, go with some Pacesetter LT's and Y-Pipe to up th HP a bit! Good Luck with your decision!

lol Who ever told you that doesn't know what they're talking about. They did get it right about the Flowmaster not flowing as good as the rest, but steel or stainless steel will both flow the same if they use the same chamber designs. That, and my last Flowmaster was stainless steel. Wasn't POLISHED, but it was matte finished stainless. I thought all Flowies were stainless.

But you are VERY right about the catbacks flowing the same whether they are SS or not.
The only thing to make a catback flow more man, is to open up the tubes (from 2 1/4" to 3" or whatever) And to eliminate any restrictons that are in the exhaust such as the chambers in the muffler or kinks in the tubing..... Thats why most aftermarket catbacks are Mandrel Bent! So whoever said that was a Dumba$$! Buy a 3" catback....And to find out which 1 you like the most you can check out LS1Sounds. Some will sound a lil different if they are on a LS1 though keep in mind.

But like Formula350 said it doesnt matter whether it is stainless or steel. What matters in terms of flow is the muffler and what type bends are used. The best flowing bends are mandrel bend which are smooth and do not have ripples in the material on the inside of the bend.

Negative the flowmaster cat-backs may have stainless steel tips but they are aluminized steel...which i believe is better than a plain steel when it comes to rusting. Stainless would be the way to go...never have the rust problem. I believe magnaflows are stainless or at least offer a cat-back that is fully stainless. Thats what i have on my DD 96 V6 firebird. Got stainless because i didnt want it to rust and then have to buy another cat-back.

alright then now I get why they don't flow good.. I just keep seeing stay away from Flowmaster so just wondered why. now I know!
I guess I'll pick up this magnaflow Cat-Back and some LT headers as well kill 2 birds with one stone
any choice on LT's for the LT1? Pacesetters are cheap but are they worth it I need it to be emissions legal!

My CORSA is 100% stainless steel
...but it was about $1000 installed.
Magnaflow makes a good system. You may not be able to tell the difference because of the low HP numbers, but almost everything flows better than flowmaster (on fbodys at least). I'd jump on that deal.

Hey guys, just reading your coments. For what its worth or maybe to comfuse you more, I stuck a hooker cat back on my car and I think it sounds wicked. (No cats and edelbrock headers with the "y" pipe.) Anyone know how my set up compares to the magnaflow or flowmaster
Mmm did your check engine light come on? it throws a code if your cats been removed without tune
If you have emissions where you are at. I'd go with LT's with cats after the LT's and try that.
If you Fail though, you'll have to go with some midlength headers. Such as Mac Mids. You can keep the factory Cat or use a bypass tube if you ever want to get rid of it. They flow well and offer almost as good of power as the LT's do. Either way you'll have to get the emissions style headers. Good Luck Man!
BTW: Flowmaster mufflers are just very restrictive in the muffler. And usually have kinks in the bends.
