Hey guys has anyone put on the boss H-pipe on their GT, I know AM sells one. I was thinking of doing this with the borla s type. How about cutouts? Or do most people generally use a X-pipe

 

Other than doing a Boss clone, I never understood the point of this setup. To each his own, I would never put someone down for their exhaust choice and that's not what I'm getting at here. I'm just thinking in practical terms I don't see the benefit or intrigue of having 4 exhaust openings. And a side exit that exits under the car that you don't even see. I could understand if it were a side exit only where it exited in front of the tires where you could see it. Again I'm not putting you down for choosing or asking about this setup. I guess more or less I'm looking for an explanation as to why you wouldn't just do a traditional side exit and be done with it.

 

The side pipes are more for a distinct sound than more flow. I love mine <3

 

Let us know if we can help you out. I actually sold Steven above me my quad mid pipe that we took off our 13 Boss. There is a distinct sound for sure and it gives it a more deep growl. The sound difference is noticeable and paired with the Borla S types its very sexy! I know, I had that setup

The cutouts are pretty unnecessary but its in option.

 

Forgive me if I came off rude at all. I just don't know anyone who has a boss or the exhaust setup and I've only seen one boss in person so far so I guess I needed to listen closer to the tone. Ill be sure to pay more attention next time to the sound.

 

Drive one.
You might change your tune (pun intended)

I was like 'that's cool, but meh'
then I heard some cars with it....and then I drove a Boss302....

My side exhaust comes in tomorrow

I think (and I could be wrong) but stated above its more for sound experience than just pure performance gain.

 

I definitely want to go for a different and more aggressive sound vs all the other GT's in my area, performance wise is the Boss H-pipe going to sacrifice much power vs an X-pipe.

 

I can't speak for the 302 crowd, but I know when I put the FRPP X on my 4.6 a while back I compared it to the stock H with the same Borla S-Types.
It was a bit louder and a bit smoother. WOT was definitely louder and more....angry.

The side exhaust kit on the 302 and 5.8 is an H.
The X is on the 4.6 kit only.

I have no idea about exactly how much power is gained in either situation.
I'd guess minimal, but I have no idea

 

That's what I'm banking on, I really want to run a boss setup underneath with either the Borla s-type or magnaflow street. As agreed its mainly for sound and if I don't like the sound I can always switch.

 

I run long tube headers and an o/r x pipe so I'm not sure if I can run the boss setup with Long tubes. Can I?

 

I noticed a setup catted shorty boss h pipe on AM built specifically for running long tube headers, it's worth looking at it might fit for you, it's made by kooks http://www.americanmuscle.com/kooks-...pipe-boss.html
It says for boss or gt500 so it may not fit also says for running kooks long tube headers. You'd have to email them or get a more experienced man than me answering haha

 

I have a novice question, will this effect A/F ratio, or the back pressure myth, any need for a custom tune, haha I know I'm a rook, ill be getting a JLT cai and either a 85 mm or L&M 87 mm throttle body along with the boss 302 intake and 4.10 gears so I know I have to tune for that, just didn't know if running the boss h-pipe and exhaust made an airflow difference requiring tuning

 

The Boss side pipes sound awesome, worth the money if its in your budget, and gives you options like how you use the restrictor plates, installing a cutout, and how pair them with axlebacks. Its really a matter of personal preference - there are lots of great sounding exhaust options. The main arguments I see against it are (1) relatively expensive (2) heavier than stock and most aftermarket mid pipes and (3) limits your options if you're planning other exhaust upgrades like x-pipe or wider diameter piping.

 

I have the boss side pipes paired with the GT500 AB's, and I love the way it sounds. Like others have said, it adds a deeper growl to the exhaust, and makes some cool noises when engine braking. With the restrictor plates removed, there is a slight drone at 2k, but because I have 3.73 gears, I'm usually above that on the highway anyway.
I don't know where this myth of a lot of added weight comes from, the side pipes only add about 4 lbs over a standard h-pipe.

 

Have you considered the borla midpipe and over axel pipes to match your s-types (full cat back)? It would be about the same cost as the boss h-pipe and would also add some sound.

 

I have the ford product boss pipe mod on my GT and put on QTP electric cutouts. I left the mufflers stock. With the electric cut outs I can dial in the sound I want. For fooling around run the side pipes wide open, for long highway cruises where the noise rapidly gets old and fatiguing I can dial it down to stock sound.

Its for the sound - no power gain and none lost. A bit of fun for a very simple mod.

 

Is buyfordracing.com still the cheapest option on this? I think they have them for $699. Anyone found a better price?

 

- Exhaust changes that are passed the cats/sensor, no tune required
ie: mufflers/mid-pipe that doesn't change the cats.
- gears, no tune other than updating your gear set for the speedo
- CAI, tune 99.9% required

Weight wise, these things are only about 35lbs. Not really a crap ton.

 

I think a company called stainless works ?? makes a version

 

For me that's the point. You don't see it. But it sounds amazing, and different than the boss as well.
