Okay, now that I've driven my V-6 with the Flowmaster single exhaust a while, it feels like it has a little more "spunk," and the wife noticed it too....About how much of a horsepower increase would any of you guys in-the-know say it gained?
 
well

well to be honest i wood say about 3 to 5 Rwhp at the most (BTW) Throw Some Rally Stripes On That Bad Boy Man.. Mine Dident Come Out That Bad lol Gotta Love That Vista-Blue.

That ride is clean man nice job.

As far as the HP gain I would have to agree. Just remember that the stock mufflers are extremely restricting so I'm sure you can feel the extra hp a great deal. Good luck with them.
 
Get duals. and order the pipes off the internet... Or else you are gonna end up bending pipes all day long trying to get the perfect fit like I did. I started at 11am and I didn't start welding until about 6 or 7.. but she was ready for a late night spin to wake up the neighbors. :hihi:
 
Dual exhaust has shown incredibly insignificant gains over a good single performance muffler, on the 2005+ v6 Mustangs. I've got the Flowmaster American Thunder on mine and love it. At first I went from stock to a GT take-off and then to the Flowmaster. When I switched to the GT muffler, I felt a very nice increase and a little more increase after going from the GT muffler to the Flowmaster.

A lot of places claim a lot of different numbers but 10rwhp is ballpark for a muffler upgrade on these cars. They've been dyno proven to show as high as 16rwhp increases on some cars though. :D

WoW, man, if I got 10rwhp outta my just installed Flowmaster Am. Thunder single exhaust on my '06 V-6 then I am more than happy! :shiny: It really feels like it's got more over stock, but just how much is kinda hard to tell....
 
Dual exhuast don't do much for the V6 it is a waste of money if you are looking for performance, it looks nice but as far as increase in HP it really does not increase it by much, go with a CAI with a tune that will give you a nice HP increase about 40HP.

umm 40 hp for a GT maybe but definetly not a v6.... i have a CAI tune and american thunder axleback, AND headers and i doubt i even got 20 hp out of it :headscratch:
 
There is no CAI/tune combo that's going to yield 40hp on either car.

I'm with you STL but I wonder if when people throw out numbers do they mean crank or wheel HP? I always speak on WHP as that is what you actually use. If you can get a 10% increase of the stock crank HP and get that to the wheels, namely about 30 on the GTs and 20 on the V6 then you are doing great. The math works on the GTs but the sixers are more around 8% -9% increase.

I don't know how to translate WHP to crank HP so if you added 20 WHP I can only guess what the crank HP would be; and the guess would probably be wrong.
 
Question?

Do you need to do a reprogram with a flowmaster or other exhaust mod?

What is the GT exhaust I see mentioned over and over - is it what it sounds like - an exhaust of a Mustang GT? Where would you get one and are they really cheaper then a flowmaster? Will extra noise be annoying? Just looking for something along the lines of a stock GT throaty sound and maybe a small HP and MPG gain. Also - are these simple bolt ons. (plan on staying with single exhaust).

Just got my stang. It's a 2006 Stampede edition and man was I impressed with the power of this base engine! I've owned two 1972 V8 mustangs and this pony is at least equal in performance.

Where can you get a GT axle back? Ebay, this forum, several sponsors to this site and so on, use the search feature above.

Is it simple? If you have a metric box wrench and socket it should take you between 30-45 minutes and you don't need to jack up the car either.

I've heard the GT takeoff on a v6 (helped put one one a friends car)
and it's mellow but a nice improvement over the stock piece.

Expect to pay about $50-$75 for the item. I don't know what the other brands cost ie FLowmasters etc ( I have Pypes street pros because I like loud) If you want an inexpensive, simple improvement to a sixer, then the gt takeoff should be your first step. :youcandothis:
 
Flowmaster American Thunder on the exhaust sounds good. But which CAI kit and tune do you recommend for a V6?
The JLT combo from American Muscle seems to be the most pouplar one. It's the one I will be getting when I get mine
