Exhaust hardware: the small parts that hold the whole system together

Exhaust hardware is the studs, nuts, clamps, gaskets and hangers that bolt a system to the manifold and hang it under the car. It is the least glamorous part of the job and the part that decides whether the install seals, stays quiet, and comes back apart next time. Manifold and header studs take repeated heat cycles that seize and shear factory fasteners; a proper stud kit gives you clean threads and even clamp load. Clamps join pipe sections without welding, and hanger kits carry the weight off the rubber isolators so joints do not crack.

What ThreePiece stocks

There are 95 products in this category, priced from $5 to $249 - the current range for what is in stock, not a fixed price. The lineup runs across 21 brands, led by Vibrant with 41 items, then Torque Solution with 11. You will also find Bike Master, BBK, Innovate Motorsports, Kooks Headers, Mishimoto, Turbo XS, BLOX Racing, BD Diesel, Fleece Performance, Stainless Works and ARP among others.

Concrete examples: the Vibrant 5in aluminized HD 2.0 clamp assembly and the 4in version cover large-diameter joins; the ARP LS1 header stud kit and the Fleece Performance Cummins manifold stud kit (also in a 4mm Allen socket head) handle the manifold end. For hangers, the Torque Solution complete hanger kit for the 2013+ Ford Focus ST is a bolt-in set.

How to choose

First decide which end of the system you are working on. Manifold and header studs are chosen to fit a specific engine and bolt pattern - the ARP and Fleece kits above are examples, and the two Fleece head styles differ only in drive type, so pick the tool clearance you have. Clamps are chosen by pipe outer diameter, which is why Vibrant lists 4in and 5in versions; measure before you order. Hanger kits are usually vehicle-specific like the Focus ST set. Price generally tracks how much of the job the part covers: a single clamp or gasket sits near the low end, a full stud or hanger kit near the top.

What else you need

Hardware is bought alongside the parts it holds. If you are replacing pipe, see Exhaust Pipes and the joining Exhaust Flanges. Doing a full system means Cat-Back Exhaust or an Axle-Back system; header studs pair with items in Headers, and clamps and hangers finish a Muffler swap. Browse everything under the parent Exhaust section.

Fitment and ordering

Fitment data is recorded on 16 of these products, sampling makes including Subaru, Dodge, Ford and Acura across model years 1994 to 2023 - treat that as a sample of coverage, not the full list. If you are not sure a stud, clamp or hanger fits your car, get fitment help by phone at 813-535-5801 before you buy. Every order ships free, and Affirm and Katapult financing is available at checkout.
