Why this one
Dimensions per variant, priced per variant
Fabrication buyers compare numbers, not adjectives. Each size carries its own price and its own row, so a quote does not need a follow-up email.
Titanium and how to weld it
The grade decides filler, purge and heat input. Getting that wrong is how a good part becomes a failed joint, so the weld notes are on the page.
Stock counts and real dimensions
We publish what is actually in stock and what each option measures, so a quote does not depend on an email reply.

Check alignment after welding, not before.
Before you order
Questions worth answering first.
How do I weld titanium?
Titanium needs full argon purge inside and out with dedicated tooling. Inconel takes nickel filler and a slower puddle. 304 welds with 308L and no purge. The grade is in the spec table above.
Can I return cut material?
No. Uncut and in original packaging, yes. Cutting is irreversible, so confirm the size first.
How do I confirm fitment?
Send your vehicle year, engine and a photo of the mounting area. We will confirm the fitment boundary before you order.
Is professional installation recommended?
Yes. These parts are built for performance exhaust work and should be installed by a qualified technician.
