I’ve bought a ton of pumps from them and they literally have single pumps listed on their website...

I even told them I was installing a Radium fuel rail. Didn't make a difference.

Must be a supply issue or something. They have all the pumps listed on the site but no way to add them to cart. I bought an individual pump from them back in feb.

Alum for exhaust is fail mode as well. I sold my alum STM 3 years back because it flexed so much you couldn't keep bolts on it. It's not made to get HOOOTTT or stay that way for ANY length of time. That and after 1 weekend it got 3 dents in it from just normal track rocks. Shortly after STM backed it down to "drag racing only" and ultimately stopped selling it about 6 months later I believe. I suppose I've had all 3 of their exhausts in the last couple years lol. Ti has crazy heat shielding/sheding properties too. After a qualifying run of 5-6 laps at full tilt with no cool down laps I can come into the pits, shut the car off, and 60 seconds later put your hand flat on the exhaust and it's just warm to the touch. Amazing stuff.

The Tomei is not quiet, which is what i think Kyoo is going for.

That's what I would have done if I had to "build it". Save the money on the expensive Ti muffler and make it straight all the way back and play with the test pipe section for res/muff on days I need it quiet. Saves a ton of room back there to do the diffuser properly.

The consensus however is that a muffler in the cat section isnt nearly as effective as out back in stock location. I dabbled with the concept of a quiet lightweight exhaust but in the end I sold the Tomei and put back on my RMR and took the weight hit. I hate sounds restrictions. Like I get it but its still annoying. As it stands I can barely meet sound at our local venue with my exhaust which includes 2 resonators and a muffler in the catback portion along with a burns muffler where the cat is AND a turndown. My catback is super old so the packing is probably nonexistant but its wild that my car is still considered loud.
Custom Ti exhaust sounds like $$$. You're probably better off starting with a Tomei and then just welding in some additional mufflers. Of course the wall thickness on the Tomei is paper thin (light) but that also makes for more noise. Curious what you come up with here as I still want to do something but as Dallas mentioned, were talking weight on the bottom rear of the car so its quite possibly the least important place to pull it.

The Tomei uses slip joints so if you keep with those style of connections you wouldn't need to weld necessarily. I agree the wall thickness is very thin.....I can bend the edges on the connections almost by hand. One of the best ways I found of decreasing exhaust noise at WOT is actually to run lower boost.

Just picked up project X from the shop with all the trans/clutch work. Can't tell you how happy it makes one to daily a turbo car with the "woosh" sound again. Everything tight and neat, I put new brakes, lines, calipers, coils, bush's, the works. However....both back RPF's are out of round, so to get two more or to change it up..hmm. This one, on topic, has a VERY well built Ti exhaust out of a company called TopSpeed in CA where it has two little resonators in the left and right sections before it bends back towards the bumper. No cats, no muffler, hopefully the emissions guy doesn't use the mirror and only scans codes lol. But I can attest it it quieter then my 9 STM and quieter then any Tomei. But it would still blow sound at any track I'm sure. All I'd have to do here is add the test section.
