I ended up getting the pypes kit from AM and I've had a few problems with it.

First was that I cut the y pipes too short, (thought the pipes lined up together rather than inserted into one another), but I got that fixed by welding on a bit more pipe. The instructions could use a few more pictures.

Another problem is that my passenger side muffler is touching the bumper and I can't figure out any way to get it to drop down a little. I've loosened all the pipes adjusted them around but its always touching.

The third problem is the drone around 2000 rpm, it's so damn loud! I don't know if it's just be my muffler and bumper touching but I think it's starting to bother my hearing. Any way to fix this drone? It sounds great at all other rpm's and I've had someone else drive it and you can't hear that drone from the outside.

You can buy stainless steel shorties on ebay for about $130. In fact I just bought some about a month ago. I haven't installed them yet, but I will.

Posted this below and then saw this thread lol. :
I got a 07 v6 pony package a few months ago and have a list of mods to do to it over the next couple years. I already did a couple little aesthetics by putting on a shorty antena, adding a billet grill around the pony grill and add some welt to add an interior trim. My first "real" mod is going to be switching to dual pipes next summer. I read that people like the gt take offs so I was going to try to get a used pair off ebay or craigslist and get my local shop to cut my Y pipe, fabricate me another mid pipe, cut my bumper and put on the gt take offs. I ran into a kid in a local parking lot that had the shop convert his to duals ( I stopped him to ask) for I think he said 400-500 including new exhaust parts. I asked him what kind of pipe they used H or X and he said he didn't know, I'm thinking they just cut the pipe on there like I want to do.

Now I just found a pair of 2010 gt takeoffs from a dealership off a car with supposedly less then 50 miles for under 50 bucks, and they are local to me so I can pick them up. My only concern is the 2010's might have changed and not fit the 05-09's..... So long story short does any one know if they will fit? Will I have to replace both mid pipes?

Oh I was totally not into cars since I was about 17 until I got this mustang just for a fun daily driver, started lurking these forums and americanmuscle etc... plus my boss is a mustang freak (just got a new 5.0 GT his 6th mustang) and keeps feeding me these magazines..... it's addictive. I'm trying to learn as I go along here

Just installed FRPP Duals

Cost was a little over $600 from CJPonyParts - the kit came with the Bullitt mufflers. I had access to a lift, so it was fairly easy to install. Ford calls for removing the passenger side converter to install the x-pipe, but we were able to install w/o removing the converter by cutting the passenger side pipe about 1/2 inch shorter than the driver side.

Getting the Rear Fascia Trim bolts installed was a real pain, due to very little clearance behind the bumper cover to get the nuts on the bolts.

Took about 3 hours to install. The only issue was the driver side rear muffler hanger rubbing against the bumper mount - I will trim off a quarter inch or so from the hanger with a Dremel for clearance.

The big chrome muffler tips look great, and it sounds much better than the factory single exhaust, especially at WOT; the car seems to pull stronger above 3000 RPM, will do a few runs with the G-tech in a couple of days to see if there is any real improvement.

I'm looking at doing stock headers to a custom midpipe to Pypes Violators pypes exhaust for mustang gt 05-09
with an NTO valence.

Any thoughts on this set up? It'll be a true duals conversion, most likely x-pipe. anything i should watch out for?

I would say get some flowmaster pipes. I had my v6 converted to pipes on both sides and it sound great. Not too quiet, not too loud...just right

Okay, okay- I know this thread is popular but we newbies need the info! But does anyone have a good, loud and power increasing exhaust set-up for CALIFORNIA (the state of suppression!)? Everything out here is illegal for emissions so what in God's name can we do to modify our little V-6's to get more power and nastier sound (besides move to Texas, thank you very much....)????

nope your stock ones are fine, you are goin to cut the y pipe out and install the x in its spot.

all you will need is exhaust clamps and the drivers side hangars, a thread tap for the drivers side hangars (holes are there not threaded).
