That is why we offer Pypes 2.5" Stainless Steel Replacement Flow Tube Kit. This kit will replace the piping between the Mid Pipe and the mufflers for a perfect installation.

Durable Stainless Steel Construction. Pypes uses sturdy 16 gauge 409 stainless steel mandrel bent 2.5" tubing with a ball and socket-style connector for improved flow and includes a set of two 2.5" 304 stainless steel flanges.

Application. This Pypes 2.5" Replacement Flow Tube Kit is designed for use on the 1979 to 2004 Mustangs when replacing the stock mufflers with aftermarket mufflers or resonators.

Great fit

Perfect fit for install. Great purchase. I wanted a cat back but didnt want American Thunder. I wanted the original 40's. So I bought the kit on ebay plus these.

can you use these to replace where the catalytic covers were welded on? or can i use any kind of straight pipe for that?

jiinkx

  • These Flow Tubes are designed for when you replace stock mufflers with aftermarket mufflers or resonators. You may be able to use these to replace the catalytic converters, but it will not be a direct bolt on because of how the tubing is bent.

    Flow tubes

    These are a great option for the guys that don't want an out-of-the-box exhaust system. Now I have one more thing on my car that I can say I "custom built". The tubes are 16.5" and 18" long, which gives you plenty of extra material to trim off if needed. What they don't tell you is that they are side specific...there is a left and a right tube.

    Flow tubes with m-80s

    Installed these with a set of m-80's. With an offroad X-pipe the engine sings without choking. Bolts right up to existing midpipe and fit right in to the the Pypes m-80 mufflers with some 2.5" clamps. This setup flowed so much better than the old chambered mufflers on my boosted mustang that I had to retune.

    Pypes flow tube

    Great product! i used these on my 04 GT when i did my exhaust. They fit great and the only thing you might need to do is cut them to length but other than that the pre-bent tubing is perfect. This item is a must have if you want to keep that 2.5in flow from your x-pipe to your mufflers which is important.

    Flow Tubes

    Started replacing my old flow tube yesterday. The new ones I bought, fit like a glove. I put them on and I welded them up to my Magna Pacx I already had. No cutting involved. I would recommend this to anyone wanting to replace old exhaust tubes.

    Great for custom install

    These are great pipes if you plan on building a custom catback, I used these with a set of Pypes Violators and American Muscle tailpipes. They went in easy and didnt require any trimming.

    Nice Fit

    I really liked this product becasue it allows you replace just a small part of your exhaust when your switching out your muffler and not the whole exhaust system. It also is like an oem part so installing it was really simple. I would suggest getting it to anyone just looking to replace their muffler because it is a cheap investment, plus you have some new hardware on your older vehicle.

    ok

    they are nice for the x pipe for easy bolt on but there only supposed to be torqued to like 25 ft lbs or they bend super bad , i went 20 and they still bent and made the seal no air tight. they should be v-band clamps for 50 bucks.

    Awesome fit

    I installed a new BBK H pipe and BBK Varitune muffler and these pipes were just the thing to bridge the gap between the two units. Fit was perfect and installation took less then 30 minutes. They are a awesome quality product. Shipping was fast and everything came packaged well.
