Flowmaster vs Magnaflow

[97cavalier]

so i know magnaflow has more and better flow than flowmaster but i love that flowmaster sound. But i have been thinking lately and i think i will go with magnaflow. How much more flow does the magnaflow have over flowmaster? And how much hp will i see when i put a magnaflow muffler on over stock?

Just muffler?? Most gains are seen in doing the whole cat-back... the muffler will help a little but you will still have the restrictive factory piping

[97cavalier]

well i am doing headers also, but i said just a muffler because it has new cat back on it but i think it is stock, there is like almost no bends except the one by the muffler, so that is why i am not going to waist money on the cat back pipe. I am also later doing the lt1 cam, so it should sound nice.

Flowmaster = Suck

Magnaflow = Good sound, and they flow very well.

What size tubing is on it?

get dynomax super turbo, 3" in/dual out.....j/k i know thats not an option.....i agree get magnaflow

[97cavalier]

it has stock 2.5 pipe, and when my headers come in, i will get them on.

[Nate355RS]

lol, why did you only get one header?

[97cavalier]

ops,lol sorry i ment "headers"

[Savage Messiah]

its got 2.5....


Get a 3" magnaflow catback on that biotch

i have flowmaster, i love it, truly i don't give a fuck about a few horses in flow loss, i'll gladly sacrifice them for the sound

I agree. I like the flowmasters that came with this car. They are also louder than the loudmouths I had on my other car, and they also sound better. I just can't wait to hear what it sounds like with the LT headers I get later.

Anybody out there have any numbers that prove flowmasters suck? Like horsepower difference between the two, or flow numbers or something besides just opinion? I have a flowmaster on my car and it sounds awesome to me, and I'm just wondering why a lot of people don't like them. You can say it's the design that makes them flow better but I would like to know just how much better. A 3 horepower differance isn't enough to say that they just flat out suck, especially with the $$$$ differance between the two.

[97cavalier]

ok, i did not know it was only like 3hp or so, if so i will go with flowmaster, i love them and the sound, i never had magnaflow but i have headr them befor and i don't realy like them. i just thought i would give it a try with the headers and my lt1 cam.

Flowmaster > Magnaflow
Flowmaster sounds better on my V6 then a Magnalow does on a 30th Anniversary Edition.
