Custom fabrication & exhaust.
Bolt-on parts fit most cars. The interesting builds need metal made to measure — a header that clears the swap, a downpipe that feeds the turbo, an exhaust that sounds right and flows better. We fabricate it in-house, weld it clean, and — because we tune under the same roof — make the calibration match the metal.
What we fabricate.
Custom exhaust systems
Cat-back, turn-down, or full custom — mandrel-bent stainless routed for flow and the sound you actually want, not whatever fit off a shelf.
Long-tube headers
Installed and, when the application needs it, built to clear. The biggest bolt-on gain on most V8s — and we re-map the tune to use it.
Turbo & downpipe work
Hot-side piping, downpipes, wastegate plumbing, and charge piping for boosted builds — fabricated to fit the turbo you actually chose.
Brackets, mounts & one-offs
Swap mounts, catch-can and reservoir brackets, intercooler piping, and the one-off pieces a real build always ends up needing.
Metal and calibration, together.
Most shops that weld can't tune, and most shops that tune farm out the fab. That gap is where builds go sideways — a beautiful exhaust that the tune never accounts for, or a turbo manifold nobody calibrated around. Everything here happens under one roof: we fabricate the piece, then tune the car to the airflow it changed. One standard, one throat to choke.
It's the same in-house discipline behind our engine builds and CNC head porting — measured, documented, and proven on our dyno before it leaves. If you can draw it or describe it, bring it in and we'll tell you honestly whether fabrication is the right answer or a bolt-on will do.
Common questions.
Do you build custom exhaust from scratch?
Yes — full custom systems in mandrel-bent stainless, routed for flow and tuned for the sound you want. Cat-back, mid-pipe, or the whole system, built to your car rather than adapted from a kit.
Can you install long-tube headers and tune around them?
That is our favorite combination. Headers are the biggest bolt-on gain on most V8s, and running them without a re-map wastes the work. We install and re-calibrate in one visit.
Do you fabricate turbo and supercharger piping?
Yes — hot-side manifolds where needed, downpipes, wastegate and charge piping, and intercooler plumbing, all built to fit the specific turbo and setup you are running. Boosted builds live and die by the fab quality.
Stainless or mild steel?
Stainless for anything you want to last and look right; mild or aluminized where budget matters and it lives underneath. We will spec the honest trade-off for your build.
Can you modify or repair an exhaust I already have?
Often, yes — we can re-route, add sections, fix cracked welds, or adapt an existing system. Bring it in and we will tell you whether a modification or a fresh build makes more sense.
Do you tune the car after the fabrication?
Almost always — that is the whole point of doing both in-house. New headers or a full exhaust change airflow, and the tune should account for it. We handle both so nothing gets left half-done.
