Presenting a fully 3d printed 4” downpipe (for test fitment only)!

We are just to proud of this prototype project we created for .jpeg not to post it right away! (We will let them tell you what it is for). But it is so cool what shops and businesses can accomplish w/ the technology we have around us today! We cannot wait for all the other fun projects and products we are gonna assist the their team with!

2025 was a hard year for us. We blew up and then we failed and let a lot of people down. 2026 is gonna be a new year for us w/ a lot of changes coming. We hope this year we restore our name in the automotive industry and make all of your proud again.

Happy New Year from all of us here at Unsupported Performance! Wish hope all our customers have an amazing year.

Completed a fun little job on a Chevy S10 yesterday. Customer bought a set of aftermarket mirrors and they ended up leaving a huge gap between it and the door. We took our measurements via 3d scanning/ calipers and off to cad things went. Once we had a working model we liked it was off to our 3d printers. Very cool how handy scanning and printing technology has become!

If you need something similar or a custom part made either for permanent use or for r&d purposes pm us today!

First pics is the oem mirror. Second and third pic is the aftermarket mirror w/o our spacer plate. Final pics are the aftermarket mirrors with our spacer.

Due to incoming tariffs, there is a likely scenario that we will have to adjust prices on most of our items since most of suppliers and vendors source overseas. We’re monitoring agreements as new updates come regardingg certain excemptions.

If you would like the best price possible, order before the beginning of April, and we will do our best to get your items ordered before prices change. Deposits do not count to reserve pricing, order must be paid in full.

We apologize for the inconvenience.

Orders already placed, have nothing to worry about.

To the few inquires I have gotten about these flamethrower kits.

If you are in Chambersburg area hit Alan Archer of AMA Motorsports.

If you are in york area hit up myself at Unsupported Performance

Couple points to note.
- customer must provide the kit I do not sell them.

- we prefer to install hot licks kits only, link provided below.

- please buy ss weld on o2 b**gs or have us buy them for you before install. (Unsupported Performance, sell the b**g kits)

- labor cost is $90 an hour for hot licks kits and $100 an hour for other kits as more modification is required. This applies at both shops for these kits and kits take roughly 4 hours to install. Youre looking at $360-400 for the install.

- kits will not be installed at either shop until appointment has been made through Travis Liller or Joel Saudwe from Street Distortionz LLC. THESE ARE YOUR POINTS OF CONTACTS, THEY WILL REACH OUT TO ALAN AND I. Alan and I will not setup a appointment in our calendars if you reach out to have this done (this applies to flamethrower kits only).

The kit in the video is not a hot links kit, which means no controller warranty or ss o2 b**gs to weld on. However it turned out to still be a quality kit, minus the jam nut to weld on instead of the o2 b**g.

If you use code SinisterBoost during checkout you’ll get free shipping.

Thank you for your inquires everyone and I hope this answers everyone’s questions who reached out.
