Magnaflow Mufflers....

As you can see from my old set-up they are slightly angled out....but not much. I figured I would do something a bit different.
I'm trying to get that "Carson Tuned exhaust" look.......

. I am very please with the sound, performance and looks of the Magnaflows more so than the two stock straws that came from the factory.

Before the break in, the car felt a bit lethargic and the mufflers would drone at 60mph. Now after almostt a year with them, It does not drone, It has a beautiful tone especially when your in a tunnel

i just got mine today and i went to have them installed and they were telling me i need the ones with the offset is this true? or do i need to go to a midas kinda shop and they can do it for me? is the setup the same for both the 300 and 400/430's or is it different?

I'm pretty sure its the same exhaust. Thats what I've been saying in my earlier posts.....it is less of an agressive angle for the input if it is offset. Then you can go either center or offset for the output. I was under my car when the shop was doing it....so I could see what he was talking about.
So basically I would do an offset/center...or a offset/offset if it was me. I'm doing the offset/offset.
Good luck...

Yours looked just like mine.....angled out just a bit. Looks great.
Tuddy: If you want them straight out (parallel) with the heat shield....if may be easier with the offset input. The shop should be able to install them like Dashockers and mine...if he can't ....might find another shop.

Question for you AZDesertGS, I just bought the same muffler and tips that you have and was wondering if you welded the tips straight to the muffler or if you had to extend them to be flush with the stock rear bumper?
Please let me know. Thanks!
I want to get the tips welded on as soon as I get the mufflers and then wait till beginning of April when I take my car out of storage to get the pipes made for the extension to the other pipes.
Sorry for bringing this thread back from the dead.
