Joe, the idea I like best is the 4-inch titanium piping with the 4-inch HKS Racing Titanium muffler. Developing your own in-house muffler, and manufacturing it seems like it, would add certain costs that could be effectively minimized somewhat if all you're doing is joining your ti piping with the HKS muffler.

Can the HKS titanium muffler even be purchased separately?

The titanium exhaust piping would be great. I was just thinking that for those who wanted a quieter exhaust (such as myself), they can take this piping and join it to a muffler of their choice...such as maybe the HKS Super Dragger which is already a pretty quiet exhaust...Darshana S...

the reason this would be more than the HKS TI kit is because it uses stainless steel piping instead of titanium. has anyone here checked into availability and price of 4" titanium piping? you'd be looking at 8 dollars+ per INCH and thats if you can find a supplier to do a low volume (under 1000 ft)

If my memory is correct (much doubt about that!), I remember the Racing Titanium and Carbon ti mufflers being available separately. The original PHR turbo kits included HKS exhaust manifolds so, because HKS and PHR have done this kind of thing in the past, and if the Racing Titanium muffler is available separately, I thought it might be possible to repeat on the titanium exhaust side the same experience HKS and PHR had with HKS exhaust manifolds. I also thought HKS might favorably consider this, even if the mufflers are not currently available separately, because it would seem to be a promising business proposition and a way for HKS to keep at least one foot in the USDM.
I'm down for some 4" titanium piping to mate to my HKS muffler!!!!!!!!!!!!!!!!!
The carbon muffler can be purchased separately but its the smaller 75mm piping which defeats the plan. You can not buy the 4' Ti muffler on its own according to HKS.
I personally called EVERY vendor looking for a Ti kit the week before BF sales went on the only vendor who had one was MVP and dusty was holding out for the 19xx.xx asking price for the two he had in stock... Every vendor claimed they could be ordered but so far not one has come through. The closing of HKS USA has killed the supply and has skyrocketed demand and pricing.
I'm considering going with the Garage Whifblitz unit, they can be had for 1600.00 shipped to the USA through either Dusty or directly through Whifblitz, I've talked to them a few times. The only downside in my opinion is the Whifblitz does not come with a silencer... Which is a new priority for me so I can idle my car for allotments of time without pissing off the entire community.
MVP mentioned a project very similar to this using Greddy to produce an HKS replacement out of 100% ti... Not sure when that might come to life or if its more like the C's copy...
^ now we're talking!
How about a 5" intake pipe?

I'd be interested in the Ti pipe to hook up with the HKS Ti muffler - particularly a large pipe given an oval profile to have the same clearance as 4".
What is the availability of flanges to weld onto Ti pipes this size though?
The muffler is very well done, but the 4" pipe is just MIG welded together and not what I was familiar with HKS products.
At least i have to say the fitment was great.
Bear in mind that it'll be no easy task adding a muffler to TI tubing later if you find your car to loud one day ... I'll be adding an additional muffler to the 4" tubing for that reason and I'm very lucky about the fact that it's "only" stainless steel and i can TIG weld it myself without all the hazzles of evacuating when doing Ti ...
im in for a Ti pipe for my HKS

I don't fuck around...but when I do, I don't fuck around!
The good news about doing the 4" piping in Ti separately, is it's ease to mount to the Racing Ti exhaust due to the "slip on style" via the 2 tension springs. This should be a relatively easy, straight forward contruction I would think for those as myself interested minus the exhaust. Seems to be lots of interest thus far, pending cost.
Not to go off-topic but 4" piping mated to a Carbon Ti (Mk4 app, not the 75mm universal canister) is just so beautiful to hear on/off throttle, especially with cams. It just howls and gives off a real distinctive pleasure note.
