Has anyone ever fabricated their own X-pipe
Maybe I'm cheap or maybe it's because I'm in charge of a helicopter maintenance facility and we can make all sorts of stuff, but when I look at these X-pipes and other bypass pipes I'm thinking they can't really cost $1000 and more, can they?
Ok I get it, the manufactures have to make a profit but I mean it's a couple feet of SS pipe with flanges welded on the ends and bent to match up with the pipes.
Anyway I'm sure there is a bit more to it but has anyone simply made their own?

Anyway I'm sure there is a bit more to it but has anyone simply made their own? Probably not too much more to it. I think the only real trick is the pipes are mandrel bent which means the exhaust flows as smoothly with as little resistance and back pressure as possible. With the X pipes there are some trial and error with having just the right amount of exhaust pulses balance each other based on the size of the opening between the two engine banks exhaust along with the ideal length of pipe the exhaust must follow before it begins putting the un-ideal back pressure on the engine.

Couldn't agree more with your take on cost and profit. Case in point $900 for the Sharkwerks Cross Pipes???
I recent read the loooong post that someone from that company who wrote concerning their R&D cost, materials, quality and even justifiable profit... after all it is a business and I truly understand that. But still, $900 for two pipes is beyond me!
Anyway, I ordered the B&B (Billy Boat) pipes from JEGS and which are basically the same as the Sharkwerks but without the center brace point. Their price $573 shipped as compared to the $764 that B&B retails it on their site. That should give an idea as to the profit margins in these products. If JEGS can retail it, WITH shipping, for $200 less than the manufacturer's retail price and still make a profit, then how much does it cost B&B to make it and still make a profit when selling to JEGS???

Agree - look at this video and you will see it's difficult. No doubt you will be able to connect pipes from A >< B but to get the right exhaust note, no drone, right back pressure and pressure waves etc I think it requires experience and calculations
There are several of these educational videos that are interesting. One about cooling etc.

IMO, for a first time design, it's a lot of time and work to get it right. For what we charge for these ready to fit, it's a stretch that it makes any sense to go down that road. It's also a metric pipe size to fit to the mufflers, which is very difficult to come by in the US. Just a lot of work to create a very inexpensive part.

Yes, we have cross pipes for the 997.1 - X-Pipe muffler delete only for the 997.2
Not sure which model you require - PM with pricing of both sent

Gundo only opens up the side mufflers. On .2 cars you still have the center muffler to deal with. It's heavy and very restrictive which is probably the reason people pay $1,000 for two pipes just to get rid of it.

The Fabspeed X-pipe is pretty well the same design except the two banks are merged for some balancing effect.
Someone mentioned in another post that you can buy an entire VW Jetta exhaust system for the cost of these bypass pipes.
Are they higher tech, better construction, better materials? While some are, most are not at all.
Anyway, my 2 cents.

Yeah I get all that and I wouldn't even attempt to fabricate a complete system but if I look at the Sharkwerks pipes, they are simply bypass pipes. No expansion, no restriction, no baffles, ducts or anything. Simply constant diameter tubing the entire length.

Agree, not too much engineering involved as bending and welding 2 equal diameter pipes together is no rocket science. Developing a complete exhaust system which sounds nice without drone is a different story.

Everything gets cheaper when produced in large quantities and everything desirable produced in small quantities tends to be expensive so I'm not sure what the Jetta analogy is worth here.
