flowmasters...

I was just about to reply here, but I don't want you guys to think I'm patting myself on the back, because I kind of stumbled onto my setup, and now I wouldn't change anything. I took a chance on the Spin Tech ProStreet mufflers, without ever hearing them, and they sounded incredible after just having them welded in. I didn't think the sound could improve until I added the Magnaflow x-pipe, now it really rocks!! :grin: I'm no expert, as I said, but every Mustang shop that I've taken mine to has said they've never heard a better sounding Stang, so I guess I got lucky. I know there are other choices that sound great too, but most drone, and these don't. That was hugely important to me, I drive over 100 miles a day on the highway. :smile:

#2971, the sound is definitely louder with the x-pipe, but it retained the low throaty growl of the Spin Techs. It feels stronger, but it was installed the day after my DiabloChip went in, so I'm sure I'm feeling a power surge from both. I'm going to re-dyno soon, and see what that tells me. Still no drone, so I'm very happy with that.

KRS 01, the model number of my Spin Techs is 6224. They actually seem to be sounding even better as I get some miles on them, but that may be my imagination, lol. :grin:
