Why does my Magnaflow sound absolutley horrible on my 300E?
I bought a brand new catalytic converter with downtubes from Catco and a Magnaflow stainless steel muffler with dual tips. When the magnaflow arrived I see right through this muffler by looking through the pipe and thought that it might be a little too free flowing...so I paid $370 to install it. Now understand that all I have is the cats, and then a pipe straight to the magnaflow muffler, no pre or center muffler. The conclusion? It sounds absolutely LOUD, its annoying on the highway and higher RPM accelerating sounds really tinny and horrible maybe worst than a ricer.
Where did I go wrong?

Just because your friends car sounded like **** with a Magnaflow Muffler doesn't mean Magnaflow is a bad company.

Also, Keep in mind that Magnaflow isn't JUST made for "muscle cars." Clown.
Anyways, A lot can factor into the sound of your exhaust. It could be the piping, the welds and etc. All I know is that I plan on going the Magnaflow route when it's time for me to get the exhaust side of my car done.

No precats or center silencer.
Not much louder then stock at idle, a little louder at higher RPM.....

Any ideas guys? I've heard magnaflows sound great on 300E on youtube. I think the reason might be because mine is a straight-through flow design instead of chambered however I would hate to drop another $150 on a muffler and then pay labor to get it Migged on just to have the same crappy sound.
my rear silencer is a custom unit supplied by Turbotechnics with 2 x 2.5" in and 2 x 2.5" tips out.
My comment was for the purpose of not running the intermediate silencer and standard cat you shouldn't have that much noise.
It's probably coming from your rear Magnaflow silencer !


The factory can mounted across the back of the car looks massive and expensive.
What do resonators do? Do E-series have 'em?
