It took me about 1.5 hours because I didn't use any jacks or ramps, I was able to slide under the car's rear end and work from there. The sound is exactly what I had expected, not much louder, but deeper with a more pronounced "burble". [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]

First, this is how the muffler kit arrived from Summit Racing, in perfect condition and in just 8 days after ordering it (from the US to Holland, mind you!):

[attachmentid=46639]

Here's a comparison shot with the stock muffler next to the Flowmaster one:

[attachmentid=46640]

Finally, a pic shot with the video camera after the installation was done and the battery of the photo camera had expired:

[attachmentid=46641]

Here's a clip of the first start-up after the install. I was surprised by the white smoke at first, but immediately realized it was all OK:

EDIT: I have a 2.9 MB WMV clip of the first engine start-up after the Flowmaster install, but I can't upload it. Can anyone help me with hosting it?

They will deepen up with time, but they won't get too much louder

I am very happy with my Flowmasters. They do seem to sound better with age.

Thanks for the idea, Bill!

First, here's a clip of the stock exhaust for comparison.

Next, the very first engine start-up after the Flowmaster install. Notice the white smoke coming out:

Nice! [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]

I'm pretty sure that's just condensation... nothing to worry about.

Thanks for sharing.

Did a chicken climb up into your mufflers??? Looks like a bunch of feather shot out at start up. Sounds good.

It's just some of the polystyrene from the original packaging.
