Just curious why you would put a Boss intake on your car if you are more interested in cosmetic mods and if you arent tracking the car why you would want all those gains up top.......way up top at 7k? Wouldnt that be more risky to your internals being in the red? Just my opinion.

To the haters, the boss 302 is cosmetic? Have you looked at your stock engine compartment it has a ridiculous plastic cover hiding the god awful intake?? That's done and as far a the Hp gains do some research the boss starts giving power at 6k rpm and it kicks in massively at 7500.

Re: Exhaust Recommendation for 5.0

I got the stainless works m11cb3l dual chambered s-tube turbo muffler cat back exhaust with the m11hdrcat headers and leads... around 2500 bucks for the setup. Sounds outrageous, nothing youd wanna drive in for longer than an hour or so, but I like loud... a lot. 1987-2011 Ford Mustang Performance Parts - Free Shipping and Ford Mustang Parts - Free Shipping! - Mustang Accessories & Parts sell the setups for it. Also if you don't want too loud, they sell a retro chambered exhaust version..

Re: Exhaust Recommendation for 5.0

I'm not hatin but I wouldn't call the Boss intake cosmetic on anyday even though it does look pretty damn nice. That plastic ugly cover you talk of can easily be color matched to the paint on the outside of the car and looks pretty damn sexy......now that's cosmetic.

Even with the intake building HP at 6K are you really gonna use that on the streets?

I don't race my car so no I wouldn't use it on the streets, I clean up after retards racing on the streets for a living so I know better than that. I simply bought it for the looks. The engine compartment looks 10x better IMO

Re: Exhaust Recommendation for 5.0

Thats the first Ive heard of someone buying the Boss intake for looks....to each his own. Have you seen the painted intake covers yet? They are really nice when color matched to the exterior.

It doesn't actually work the way you're describing, if you look at the graph you can see that the boss intake maintains HP whereas the stock one drops off gradually.

Remember the boss has stronger internals to support being at 8k rpm too, it might be better to just go with a supercharger and be done with it.

Does anyone have the Roush axelback. Thinking about purchasing it...was wondering if it had any drone in 6th on the highway. Also did it give any additional hp?

Comparing a 400.00 manifold to a 5,000 and up supercharger is ludicrous my friend and if u have money for the blower you would have been better off buying the blown car from steeda/Roush factory you actually will save money long run and cost roughly the same you can special order a GT with just the blower and graphics package for the same price as buying a gt. And parting it out yourself and installing a blower, my friend just did it. Also a 7k dollar increase in vehicle price will only cost you 70.00-80.00 additionally per month on a payment and it's warrantied with your vehicle

Graph reading>you.

Nothing "kicks in". It just doesn't fall off. You probably don't even have a 7500 rpm limiter lol. Again, you didn't gain any hp from the intake, but you did lose some torque!

U guys are killing me, stupid 5.0 I have a tune my rev limit is 7500 and 4.10 gears which basically counter acts the torque loss I'm not running stock 3.31's. What are you talking about?? The graph is with a steeda CAI and stock mufflers

AND I QUOTE

"As you can see, peak to peak numbers went up 20 horsepower. As expected though where the stock manifold falls off, the Boss manifold is no where near finished. The highlighted point around 7250rpm shows an impressive 53hp gain. Peak torque is down 14ft/lbs, but points in the midrange loose as much as 27 ft/lbs of torque.

Is this worth it to upgrade if you already have a cold air and tune? For many I think the answer will be yes, but this is definitely not for everyone.

An owner with a cold air/tune, and 3.31 gears that goes to the Boss manifold, tune, and 3.73's at the same time I think will be more than happy as the gears would absorb the feel of the torque loss. It is all going to matter on perspective and intended use."

I get where you're coming from with the intake manifold, if you're going to be at that rpm a lot then this is definitely a wicked setup. The point I was making is that all these mods add up and it might have been worth putting that towards a supercharger. I wasn't comparing the value of just the manifold to a supercharger.

That's just me though, there's at least one person out there that has over 500 at the wheels NA... I know for a fact the boss manifold is involved but it also has some engine work done of course.

No HP gains and absolutely no drone at any RPM......very nice and has a great price tag.

I put bassani axle backs on my 2011 GT. Stock they screamed but were a little raspy. Now that she is supercharged, deep muscle car sound. Neighbors hate it when I fire her up!

Do you get hit on a lot when you go to strip clubs?

Look fella, the last graph you posted is comparing a stock car to a tuned car with a boss intake. You do not gain any HP from the boss intake. You will only lose torque. With cams you could see some peak gains, but on stock internals you don't gain anything. Peak HP just doesn't fall off at 6850 rpm. The operating range of your engine shifts to the right with a boss intake.

If it doesn't fall off wouldn't that signify an increase in power or am I missing something and what happens at 7250rpm? Did u read what I posted? You gain HP?

So why the axelback rather than catback?

I don't want a raspy sound, I like the deep sound, this exhaust is beyond awesome and it's loud enough too... This is my first mustang so it's plenty fast for me... Eventually my next upgrade is a CAI/tuner combo and that's about it

Re: Exhaust Recommendation for 5.0

Catback is not gonna give you the rasp. It's the mid pipe,specifically the x pipe that will do that.
