About us....

We specialize in making turbo related products for 79-04 mustangs with 302 or 351 engine in it. We offer many different header designs and options. We build every order as it comes in so that you can custom design your order using our custom build options.  We pride ourselves on building your order checked the fitment in our in house 1991 mustang mock up car. We have also ventured into the forward n/a header market with a nicely designed n/a header that can be used as a forward exiting header. 

I highly suggest you check out our FACEBOOK page  <Click Here> or for the cautious search for "Pony Down Performance" We post build pics all the time. Here's a little preview...

Things are going good over here at Pony Down! We are building up our Naturally Aspirated forward exiting header line up. We offer the following primary sizes (1 3/4", 1 7/8", & 2") with the following flange options (3" afr/dart, trick flow high port, & trick flow 2.75". Speaking of header flanges we are no longer going to offer the edelbrock 2.5" flange for our headers. And here's a little FYI for some people that may or may not know our welding process. We TIG weld everything on all our headers, downpipes, and piping. The only thing we mig weld is the weld star in the collector area. Yes, TIG welding takes longer but it does look a lot better and our customers deserve the best! We are going to slowly make our way through the website and make sure we have the best description possible for our products. Ad coming very soon is going to be some brief info and making sure you select the proper header flange for your head. We have gotten some wrong flange selections from a couple of customers and we want to make sure you get the proper flange the first time.

Things are going good and smooth over here at Pony Down but I thought I would send out some current info for potential customers. We have had a couple of customers place orders thinking what the website shows in stock is what we have in stock and there was no wait time. Well the website has to show a quantity or it won't show up. So that's why you will see a quantity there. Any item that has to be cut and welded from headers sets on up will normally take 3-4 weeks from the time the order is placed. If you call or email you can get our current build times. Another quick thing to throw out is that we do all orders through the website. It makes our lives better by doing what we need to be working on. That's spending time fabbing and welding.

News - 2/25/16


With the tax time rush coming in our normal wait time of 3-4 weeks for a order is now up to about 4-5 weeks. But its a always a good idea to touch base with us to see what the current wait time is. Plus we can answer any questions you might have.

We just made our first of LS headers for use in a mustang. The design is based off our pdp R headers. As soon as we get a little more feedback on the fitment we will offer them on the website. The pricing will be the same as our R headers. We will post a update on the website once they will be ready for ordering.

Lets talk sbf header flanges 101. To see what bolt pattern you have with the side to side bolt pattern, measure across the exhaust port from  the center of the bolt hole to center of bolt hole. With that measurement you can make sure your ordering the correct flange for your order. We offer the following bolt patterns for sbf heads...

stock 2" (gt40, edelbrock performer, afr 165/185 etc...)
1487 wide bolt pattern 3" (afr, dart, canfield, etc...)
trick flow high port diaginal (TF high port, TF R, etc..)
trick flow 2.75" (TF R)

We added a new option for the R headers. If you don't want v-bands on the collectors you can now check a box and NOT have them on. We also added a 1 7/8 primary option onto our T6/T4 drivers & passenger hot side kits. But other that its business as usual. We are still working on the email problem.  

News - 7/1/15

Coming soon will be some custom services for customers. One will be some a chance to get some custom vinyl stickers made. Another option is going to be custom flange cutting. We currently cut 1/2' plate for for the right job we would do other sizes. Prices and more info to be announced in the future.


News - 6/6/15

We are adding some new things to the website. We just added a bead rolling service for cold side pipes. We are also going to start selling a custom made cold side extension. This will be a custom length pipe for a customer fill a gap. A common use for this would be for switching from mass air to speed density and having to fill the void. Coming soon will be a custom turbo inlet flange service. We can take a t3, t4, or t6 flange and custom design it for our specs. A example would be a mounting tab on the flange for a turbo support.


News - 3/9/15

Always building and adding! Well building orders and this month we are adding to the website some new options. Up new is the addition of a 5" downpipe for our T6 hotside kits. Our stage 4 kit now has the option for a upgraded turbo. The options are for a borg warner s484 (84mm) or s488 (88mm) They both feature billet wheels and race covers! Coming soon will be the option to get a 1 7/8" primaries T6 hotside with a 3" crossover with our drivers side T6 stuff.



News - 2/12/15

Getting things done and bringing new products and options out in 2015! And with that being said we are now offering our 1 7/8 headers for the 302 (8.2 deck) motors. Either one of the 1 7/8 headers we make can be used for turbo applications or for forward exiting headers. A new option that we are adding for the t6/t4 drivers side kit is a turbo support brace. The brace will go from the turbo flange to a plate that will bolt up to the front of the drivers side head. The flanges are 1/2" thick! With TAX time getting here our wait time will take longer as more orders come in. Right now we are on a steady 4 week wait for bigger orders. Our smaller orders (r headers & 1 7/8 stuff) will be 3-4 weeks. 


News - 12/29/14

We just added another new header set to the website. They are a set of 1 7/8 R headers for the 351. And we also added a new design to the R Header line up that will give more clearance on the passenger side header for the spark plug and spark plug boots. We are now able to do the 302 or 351 1 7/8 headers for the same price of $524.99

The pony down "safe tune turbo chip" will be available Nov 1, 2014!

After a good amount of phone calls and emails with questions about the pony down "safe tune turbo chip" we have decided to add a n/a tune that will allow the same options for upgrade options. We just will just use a different timing curve for a n/a car. The great thing is that you can mail us back the chip and we can change the tune to our "safe turbo" tune for $24.99. 


News - 10/4/14

Some good news to update here!

1st - We are finalizing our Pony Down "safe tune turbo chip" that will be available for mustangs or any vehicle running a a9p (auto) or a9l (manual) computer. More computers may be available in the future as we get more time for development. These chips will give your car a safe tune under boost with other options to fully customize the chip to the specs of your car. Besides a change in the timing map and other items we will also be able to increase your rev limiter, turn off your smog stuff, egr, and more. pricing is looking to start around $149.99 which is a great price to get a piece of mind. 

2nd - We just fabbed up our first prototype 1 7/8 pdp "R" header set. Yes I did say 1 7/8! We are happy with the fit and the results. But they will only be available for the 3" bolt pattern (fel-pro 1487) and the trick flow high port flanges and a 8.2 deck motor. Pricing will start at $549.99 

3rd - We are adding a new option to our pdp "R" 45 degrees headers that will make the option of making the header into a front exiting header. Pricing will be coming soon!

4th - Coming late this fall will be a passenger side t6 hot side kit. The kit will use our pdp "R" headers and a 2 1/2" crossover. The flanges will be our standard 1/2". The exhaust housing will face the water pump and the compressor housing will face the sheet passenger side sheet metal. As with our drivers side t6 hot side we build the kit and you build around our kit. The kit will require the front radiator to be relocated under the radiator support for turbo exhaust housing clearance.
