    On a recent vacation to California, I had the pleasure of renting an '06 Mustang Convertible V6! What you say? Is somebody actually going to waste the time of fellow edmunds posters who usually reserve postings for GTs and comparos with Vettes? Yes I am.

    Lets start with the positives. The car was Baby Blue with a Black top and a gray leather interior. It was handsome enough to draw some "nice car" comments from car crazy Californians. I started the car up and was surprised to hear a really nice exhaust note. The car sounds like a Jr. V8 as opposed to a raspy V6 found in other Ford products. Acceleration was adequate and the 5 speed automatic seemed to pick a gear and stick with it as opposed to hunting for gears. It did well going up and down the streets of San Francisco. Merged well onto the Freeway and had no trouble summoning 2 gear downshifts to pass people. Freeway ride was quite comfortable. We drove From San Francisco down to San Diego and not once did I feel sore or tired from driving. My wife who is over 8 months pregnant found the car to be comfortable. We drove for probably about 95% of the time with the top down and were able to hold normal conversations on the freeway cruising between 75 & 85 mph with no problems.

    Now the negatives: I understand that I was not driving a GT, but the suspension was way to soft and floaty once the road turned curvy. The brakes felt mushy. The interior plastics and dash materials were just down right atrocious (Ford should really be ashamed of themselves). I also had a gripe with the trunk. Granted it is a Convertible and luggage space is NOT a priority. For some odd reason the trunk slopes UPWARD towards the front of the car! I was able to fit one large rolling suitcase (barely) and some other small bags in the trunk while our other large duffle bag had to be put in the trunk.

    If the opportunity presents itself, checkout Hertz and a GT500 they are advertising as being available. I have an 06 Torch Red GT with a 5 speed. Nothing like popping 2nd and watching (and listening) to the fun. My 12 y/o fits in the back (not the room of our Expedition, but no complaints so far) so a baby seat will do fine (and they put anchors in to secure from the top).

    Thanks for the review.

    thanks for the review. about the handling the curves; rentals a famous for having low tire pressures.
    my other quesiton is, how many comfort stops did you have to make with your 8 months along expectant wife?
    any guesses on gas mileage?
    sounds like a great trip overall. :)
  • nyccarguynyccarguy Stamford, CTPosts: 7,659
    Even taking into account the rentals low tire pressure, it was still sloppy. Steering was decent though. My wife's a trooper, we didn't have to make too many pit stops. We didn't drive all the way through in one shot. We did San Francisco to Pacific Grove. Pacific Grove to the Hearst Castle. Hearst Castle to Santa Barbara. Santa Barbara to Newport Beach (purposely skipped over LA LA land). And finally Newport Beach to San Diego. I didn't keep track of gas mileage. The cheapest gas I paid for was $3.15 9/10 right off the end of the 8 Freeway in Pacific Beach and the most expensive was $3.69 9/10 6 miles south of the Hearst Castle. California is a beautiful state. Too bad my job and the Yankees aren't out there!

    vertical3,
    Originally I was thinking of the Ford Racing exhaust or Borla, but I've heard that Flowmaster gives the classic muscle car sound. I can purchase on the web for $288 and have been quoted $80 to install from Midas. Supposedly they sound great with not too much interior cabin resonance. Like I said, I wish I could find someone who's installed them to verify.

    On other forums, I've read where people have put on certain exhausts and found them to be too loud with too much resonance. Seems they wanted to go with same brands they put on the older model GT's (pre 2005), and due to the fact that the new GT's mufflers are behind the axle, way at the rear, with little tail pipe... it's causing more roar than they bargained for.

    As for shorty headers on these, the exhaust manifold on the new GT's is already designed like shorty headers... not like the old design with 4 seperate tubes on each side going into a "log". The Ford Racing shorties will provide higher flow though. The stock exhaust already breathes pretty damn good. Some people are putting on X-pipes only to find it gives them a higher pitch they didn't want. The stock H-pipe gives the lower pitched sound familiar to those who love the classic sound.

    For me.. I'm not looking to do many mods. Just the exhaust and maybe a cold air induction.

    Again, if anyone has put on these Flowmasters... let me know.

    Thanks!

    I'm on the hunt for an 07 GT convertible and I'm wondering if anyone can comment on the handling differences between the 17" and 18" wheels. The 18s have a slightly lower profile tire which I'd think would result in better handling, although perhaps not noticeable unless on the track. I'm thinking the best bang for the buck might be to go with the 17s and replace the stock all-seasons with summer tires. Any opinions would be appreciated.
  • akirbyakirby Posts: 7,699
    You're right about only noticing the difference on the track. Not to mention the greater choice and cheaper prices of the 17" wheels. I think a good summer tire will improve performance better than just going to 18's. They'll also ride better when you're not at the track. Once you get into 18/19/20+ you're just doing it for looks. NASCAR still uses 15" wheels.
  • baggs32baggs32 Posts: 3,213

    Yeah but they are riding on 8 tires instead of 4 for saftey so I don't think the size of their rims directly related to better handling. Rather the two tire on each wheel setup calls for a smaller diameter rim. Surely they don't need 18 or 19 inch wheels because the tires are so good which is the point you were making, but there are other reasons which I thought some might find interesting too. ;)

    sounds like a great trip, and thanks for the update.
    enjoy that full night's sleep. you are going to be going without it for a while in a month or so!
  • explorerx4explorerx4 Central CTPosts: 9,727
    i'm pretty sure those mufflers just bolt on. check it out, and maybe save yourself $80.
  • akirbyakirby Posts: 7,699
    I think they used 15" wheels even before they had inner liners. Also remember they use air pressure to make handling adjustments and the larger tires probably give them more latitude. Not to mention they probably resist overheating better.

    But I still don't think you'd see them going to 18" wheels for better handling.
  • baggs32baggs32 Posts: 3,213

    I don't either but I think it would help with durability. Less rollover, less surface area for junk on the track to hit, etc.

    I will most likely be opting for the 18" polished bullitt style wheels when I order later this year but the harsh roads here (Even Detroiters say our roads are bad :surprise: ) are keeping the option open for the 17s. :sick:
  • tayl0rdtayl0rd Posts: 1,938
    Yep, they bolt right on. You don't even need to jack the car up to do it; unless you're really fat and can't fit underneath! ;)

    Instructions suggest welding. Is this necessary?
  • I have a 06 V6 convertible, it sure does a good immitation of a V8 sound track. It also is fast about 7 seconds 0 to 60. However I have the pony package version, with the GT suspension set-up like rear anti-roll bars and stiffer settings and the GT 17 inch wheels w/ Pirelli P-Nero 235/55/17. This car handles great like a GT, the brakes are not as good as GT, and acceleration slows down after 70 mph. Everthing else is pretty much in your blog.
  • tayl0rdtayl0rd Posts: 1,938
    Welding will guarantee against exhaust leaks or the mufflers getting loose. But they can be successfully bolted in place without any future issues if done securely.
  • akirbyakirby Posts: 7,699
    A muffler shop would probably weld them for you in a few minutes for just a few bucks.
  • I realize they bolt on, but like previously mentioned instructions "strongly recommend welding all slip-fit connections".

    Question though.... If the connections are welded, can the welds be easily "broken" in case of future replacement? Don't want to have to have anything cut.

    I was thinking of having them bolted on and then welded after I determined I like them. Still haven't heard them in person or discussed with anyone who's installed these Flowmasters.

    As for installation, I think I'll just get them done for the $80. Instructions talk about possible necessary adjustments to the H-pipe if the muffler tips end up out of alignment. I'd rather someone else deal with it if problems arise. Besides, laying on my back installing these things in the 95 degree heat, is not my idea of a fun Saturday.
  • tayl0rdtayl0rd Posts: 1,938
    Check some other Mustang forums. There are plenty of sound clips of them, even on Flowmaster's own website. I've heard back-to-back clips of stock vs. Flowmaster, and the Flowmasters sound exactly like the stock ones, only slightly louder. The overall tone is identical, so if you're looking for a deep, throaty rumble, you might want to look elsewhere. The Flowmasters for the new Mustang sounds nothing like the old American Thunder 40-series does on the previous Mustang.
  • explorerx4explorerx4 Central CTPosts: 9,727
    the only reason i can see to get them welded, is to prevent them from being unbolted without your permission.

    Pretty funny- Did you actually look?
  • lavrishevolavrishevo Posts: 312
    Just a thought. People have actually lost HP going with Flowmasters. Is there any dyno's from Flowmaster showing actual gain? I'm personally against a chamber muffler truly being called performance. The whole point is to free up flow and sending exhaust through chambers does not exactly do this. I went with Borla because of quality and lifetime warranty. Plus their design really does improve flow, if you can look at the back of the muffler and see out the front that is a good thing....

  • tayl0rdtayl0rd Posts: 1,938
    I can't believe you picked up 82HP (62HP) with just some exhaust changes and a tune. Something seems fishy w/ your posted HP numbers. :confuse: An X-pipe does pretty much nothing but change the sound. The mufflers might be good for 5HP, and that leaves the long tubes, intake, cats and tune. All told, I'd say maybe 45 flywheel HP, but I could be wrong.

    "I can't believe you picked up 82HP (62HP) with just some exhaust changes and a tune."

    Well, obviously you need to find a shop with great skill at tuning Mustangs.....and great skill with a dyno doesn't hurt either.... :surprise:
  • akirbyakirby Posts: 7,699
    The stock GT already puts out about 320 hp (regardless of the advertised numbers) so that helps a lot.

    Got mine in the mail today! They look sweet, better than the aftermarket ones. They only have four holes for mounting and each hole has a rubber gromet, only thing now is to decide if it needs to be attached at the front of the throttle body or just put it on with wing nuts at the rear of the cover where it fits over the existing studs? Anyone attached one yet?
  • topoffgttopoffgt Posts: 14
    I put mine on this past weekend. Be aware that the metal spacers inserted into the two rubber grommets on the front have holes that are too small for the throttle body bolts to fit through. You can just remove them, but it makes the cover bend in slightly in front when you tighten the bolts. I may try to drill out the spacers, or maybe just buy some ss washers instead.

    Also, be careful when you tighten the back two bolts onto the plenum. I cracked it slightly on the right side at the mounting point, but it's not noticeable.
  • topoffgttopoffgt Posts: 14
    I forgot to mention that this cover can be ordered directly from Ford at any dealership for about $67.00 plus tax. They might be on back-order, but mine arrived in about a week. Some people on ebay are asking over $100 each.
  • macatowamacatowa Posts: 69
    I paid $59.82 including shipping, I don't think the ebay ones are going to get $150 anymore, now if the cold air kits would come down in price!
  • Hey if you supercharged a 06 mustang, how much hp would you get to the rear wheel's? And do you guy's know any good mustang performance website's?
