Magnaflow - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My flowmasters have decided to rust everything behind them and dispose of their baffles, so it's time for a new exhaust. The one place in town that builds aluminized mandrel bent exhausts pretty much only sells Magnaflow. Are they good mufflers? Any idea on how they sound on a motor that's not really built up? I have heard good things about them though. Also, what did you guys pay for a full exhuast, preferably aluminized. Thanks in advance.

Magnaflows sound really nice and deep when you stomp on the gas, not raspy like Flows. I think you will like them.

Really? I didn't know. I have heard they are the "new flows" but I wasn't sold on them. I have always loved Flows....

so you are saying they sound better than flows? I member with my old 2 chamber flows, at idle in drive, I would set off alarm systems...LOVED IT

Not saying necessarily better , just a different less racey sound. Not as tinney. Peregrine you should go to the shop and listen to a similar motor as yours.

I will only run Magnaflows. They are stainless steel unlike Flows and flow almost 1/3 more CFM. They have more of a rumble but are still pretty loud if you have a decent flowing exhaust. They also come with a full life time warrenty - I don't know of any other mufflers that offer that...
I made 450 horse through two 3" magnaflows so they do pretty well.
Good luck.

I'm planning on running them with 3" exhaust. I've heard nothing but good about them.

Just installed on "GQ" last week, pic's on BLAZER board, kinda sounds like

let ya here it, but my file is 80 MB, and it is to large to e-mail, ideas

Peregrine · 06-01-2005, 05:45 PM

I would go to the shop, but they don't have many small-block powered cars laying around, mostly imports. But they do the best work in town on any car you can think of. I just might have to get some put on, I don't like my flows at all. ugh

If you want diffrent mufflers thats cool but I thought Flows had a lifetime warranty, (exept in an NOS app)

Only against explosion. Not against rust.
