Anyone know whatthe stock exhaust intermediate pipe diameter is on the 05 mustang gt. I was on summit racing.com and for an extra $100 you can get a flowmaster cat back system instead of just the axle back system. I was just wondering if its worth it. The only reason I could see is that the flowmaster might have a bigger pipe diameter, allowing for more airflow.The flowmaster intermediate pipes have a 2.5 inch diameter. Does anyone know if this is bigger? Anyfeedback is appreciated.

2.5" mid pipes stock, but why flows? there are other mufflers that sound better and louder.

I love my Mac axlebacks. They look and sound sweet!

not worth it

Thanks for the reply's. I'll just go with the axlebacks. Why flows? Why not. I love the way they sound and IMO flowmaster and mustang were a match made in heaven.

the new mustangs sound completely different than the old......so just becuase the 2 and 4 systems sounded great, the 3 valve will not sound anything like it

Yeah the flows on 05+ mustangs sound kind of...meh to me. You should look into Boomtubes or Corsas. Both of those are perfect for the new stangs.

Search for the "official exhaust thread" to hear all the different kinds and read descriptions on them.

There are plenty of soundclips here.

IMO, for just an axle-back, I would pick up the Ford Racing/Borla stingers. If you want cat-back, I would pick up a bassani X-pipe and axle-back.

x-pipe is not catback, its a midpipe and axleback switch...the over axle pipes are not switched out

I read in another thread where you referenced "cherry bomb" mufflers. That is the pet name for IMCO pro series mufflers and their 55507 axle backs sound much better than the flows. I was going to buy the 17410 Flowmaster axle back until I heard sound clips of the IMCO 55507. Check out the link below.

This sound clip sold me, but for the 400.00 it cost to buy it I was also leaning towards the Pypes mid muffler system. You might want to listen to some clips from the mid muffs. I might still change to them.
