Would it be possible to get a list of all the exhausts and their power gains?

[clevernickname]

We have a sticky of the sound, I wonder if it'd be possible to get one, or even add to the sticky, something similar but with HP/torque increases.

For exhausts, intakes, everything? Or are they all fairly similar.

catback only?

All exhaust: 0 real gains.

 

[Triple Wile E]

Catback don't really give you much just weight saving and sound. Headers is where you make your gains. I'm going with ARH headers with Borla catback.

 

[beefcake]

catbacks aren't really worth any power, pick based on sound is what I tell everyone

 

[clevernickname]

oh. now i am pretty new to all this, but i thought the stock system was fairly bottlenecked through the exhaust, and the big mustang aftermarket companies were saying (about 6 months ago) that they were gaining like 30-40hp and 30ish torque. from a catback and a CAI. Was that a bit of an exaggeration? Or did they only get those numbers with a tune anyway.

What are the realistic numbers for a tune vs tune + exhaust + CAI.

If Hennessy can squeeze 700bhp through the stock cat-back, its not much of a restriction.

 

[Guard5.0]

Mine got about 30 RWHP and 20 LBFT from exhaust only, ARH 1 7/8 headers, no cats, into a full ARH exhaust with their mufflers. I'm sure full exhaust and tune get more and I know some on here have this mod.

95% of your gains in the combo you listed above will come from intake and tune. Catbacks offer very little to no gain in performance. And quite honestly with headers being a few hundred more if not the same price as a catback I'd go for the headers. You are right though there is a bottle neck in the stock exhaust system, which is why I went with American racing headers exhaust as it eliminates this restriction.

There was a huge load of bullshit surrounding Magnaflow and Gibson. They posted these videos with blatantly misleading claims of "up to 20-30hp/lb-ft" on their dyno readouts from a catback alone. It was assumed for awhile that the OEM piping was a huge bottleneck, but realworld dyno testing is showing that it's the same story as any other car out there; a power bump of any kind would be a lucky surprise, but don't expect one and don't base your purchase off of any ridiculous claims.

Gibson Performance introduces a new Dual Exhaust system to give the redesigned 6th Generation 2015 Ford Mustang 5.0 steed an extra shot of American-Made power, combined with an aggressive sound that lets others know to take notice.

thanks guys, that why i ask you experts.

@anotherneon you say there is a bottleneck in the exhaust system? so why wouldn't an aftermarket exhaust give power gains by getting rid of the bottleneck? or is the bottlneck only at the headers.

and an aftermarket intake gives decent gains? that surprises me since the car already has an intake! stock one garbage also?

 

[BathS550]

A catback is not really eliminating the bottleneck, as it is not a complete system you are still dealing with the connection between a stock component and an aftermarket one.

As has been pointed out in almost every exhaust thread, the largest exhaust gain will come from the headers, primarily through the advantage of tuning for long tube headers.

^^^

some of the manufacturers make "complete" systems that will give a full 3" system

stainless works
arh
kooks

sw and kooks make factory connection points that mate at the 2 bolt clamp
arh makes a factory connect that goes past the factory resonator and deletes it well, and can be made to work with most catbacks or any axle back

If u did headers u had to tune so that hp and tq was from tune and exhaust,not just exhaust.

If I'm not mistaken I don't think he tuned it yet.
