which flowmasters?

[bluextc]

I got my car from a used car dealer in 10/04. He was an idiot and told me the car was stock (it actually had the Flowmasters and K&N filter, and that was all from what I was able to tell). I thought I had the 40 series since I'm told that's what most people get. My neighbor loved the sound of mine, so she just got them put on her 03 GT on Friday and they are nowhere near as loud or deep as mine. Is there any way I can tell what my exhaust is myself, I've tried crawling under there and I can't tell anything except that they're flowmasters...

If you jack your car up, you can compare the weld pattern on the muffler casing; You can tell where the baffles are by doing this. You prob. have the original 40 series 2 chambers, where as your friend prob. has the "delta flow" series.

It also possible that you do not have the stock midpipe. You may check that also.
