Dual Exhaust 3" Tail Pipes?

[shotsy]

Anyone know where to get some 3" tail pipes that will fit a 70? the biggest I can seem to find are 2.5"

Summit racing......part number MPE-15819 67-70 3" Magna Flow. If I hadn't just replaced mine with a 2.5" (3" was not avalible as a kit until now) I would of bought this kit. If you get it let me know how well it works and sounds.

I've already got the X pipe and muffs, just looking for the tail pipe 's to go over the axle? 500+ is a bit steep thanks for the link

What makes you think you need 3" tailpipes? What's under the hood, a twin turbo Cat diesel?

local muffler shop should have them.

I'm runnin 550+ hp through 2.5 and it does just fine

 

[6Stang7]

eh, i would go to 3" if i were you. 450+ is well into 3".

 

[D.Hearne]

Why stop with dual 3"? Why not shoot for dual 5"? You could fab up your own system using readily available pipe for 18 inch wheelers. Be the first on the block with HUGE pipes. They'll look as cool as those show trucks runnin the interstates with dual 8-10" stacks. ( we call em "chicken haulers" )

I Didn't ask to get beat up and I'm sure that I'm not the first person to ever run 3" pipes on a mustang?

 

[D.Hearne]

3" is WAY too big. For anything but something like 500+ cubic inch motors. Spend your money on something worthwhile. 3" systems are something akin to those things you've seen advertised that make you car get 100 mpg. All hype. Nothing for your money but pipes that are hard to deal with .

Anything over 550 hp should be looking at 3" or bigger. I am looking at 3.5 " for my car. Dumps out before the rear axle though. Motor makes 850 hp

 

[brianj5600]

I'm not trying to be mean, but your sig looks closer to 350hp. 2.5" would be more than enough. I'm hoping to push 700 through 2.5".

 

[shotsy]

Ok so my exhaust is too big, I'm shooting for somewhere around 400 HP, I've already got the X pipe and the muffs in the car and they sound great, can I use 2.5 tail pipes with reducers off of the mufflers, sure I can dumb question

 

[mdjay]

I would run them if I was running this strictly on the track. They almost have to be dumped before the rear axle. They would be pretty tough to put through the back.

On my 400-450 horse 331 stoker-sixpacked 89 Ranger, I've got Shelby style Tri-Y's, into dual 2.25" pipe, they run into an equalizer tube of my own making, which is a single 4" x 12" long pipe, then back into dual 2.25" pipe, into dual 2.5" Dynomax turbo's, then straight out the rear of the truck. If there's a restriction, I sure as hell can't tell. This is a 3800 lb truck that runs mid 13's in the 1/4 mile.

The only way to tell is if you test the car with and without the exhaust. I was also looking for 3" tailpipes for mine but couldn't find them. I think if you are running close to or over 500 horse and you want to get EVERYTHING you can out of your car then 3" is the way to go. I have 520 horse and 2.5 is choking it down quite a bit. Tried it at the track. No exhaust = 11.39@119. Exhaust = [email protected]. This is full 2.5" flowmaster 2 chambers with their mandrel bent tail's. You can't really feel a difference on the street but to pick up a couple tenths is quite a bit. Just my 2 cents. I just e-mailed magnaflow to see if they would just sell the tailpipes. I'll let you know what they say.

I know my 2.5" CNC bent, over the axle Flowmaster tail pipes are a very tight sqeeze. 3" must really, really be tight?

Part of the ET gain here is the weight loss!

Wrong. When I unbolt it, I just turn the pipe out of the way and put one bolt back in the header to hold it up out of the way. I do not remove the exhaust system. Hueypilot, I was thinking the same thing. My 2.5 is tight also.
