would my 8 loose power if I take off my magnaflow exhaust and instaal the factory one back? (I bought the car and the magnaflow on it and never drove one with the factory exhaust)

It shouldn't lose any power but I am curious why you would want to go back to stock? Is the center resonator still in place?

Personally I am dithering--My exhaust is stock but I have the magnaflows sitting under the bench. Like the quiet but..............

In certain states, like Virginia, if you have any thing that is not stock/stock replacement the cops can write you a ticket for it. Espically exhaust that is louder then the cop likes.

well, it is not that noisy, but if i take the silence tubes off you will hear it from 3 miles away. i dont want all the neighbors to wake up when i pull in.

I've been thinking about getting a new exhaust for my 840. It's too bad that one can test out an exhaust to see how it sounds/works before buying it.

That, my friends, is a reason as to why I have remained stock.

I'd like a little more power (who wouldn't?) and I'd like a little more sound, but, I don't want my car to sound like a pea shooter or Rice Racer.

I just recently put magnaflow exhaust on my 850, thought the sound was a bit weak...so I had the cut the resonator off, and now it is perfect! I was scared it was going to have a cheap honda, or "boat like" mustang sound. But it didn't at all. Sounds more european...like a ferarri. It's got an accent! Ha. The hardest part was deciding what tips to go with...i'm still on the fence about my decision. Any thoughts?

Nice ride... So I assume that once you cut the resonators off, it is permanent? I wonder if your Magnaflow would sound different on an M60 engine versus your M70.

Stock exhaust on the 840 sounds better & more authetic than the aftermarket!

Hell that one of the main features of my 840Ci that I LOVE is the destintive Growl when I get on-it.

I am putting Stock when I need to replace.

Just my .02!

Now my 1988 M3, has After-market Borler Exhaust. Sounds/Breaths better. She Goes!

It's personal preference! Do what you like!

I personally do not like the rectangle tips. They are very old school Chevy / Caddy style. But it is your choice not mine. I had a choice of MagnaFlow and Supersprint and I went with SuperSprint against the common choice and been happy with it.

I do like the V8 growl! You might be right, I am not sure if it needs any improvement soundwise :)

Yeah, I sort of thought that myself after I had them put on. Oh well, at least the tips can be changed easily. Other than that, I have nothing bad to say about the magnaflow. I am sure that supersprint is great too. Anyone want to buy some rectangle exhaust tips...

I'll take them! Someone took some off of my 83 caddy yesterday!!!
