Exhaust Accessories

Exhaust Accessories: the small parts that finish a build and keep the whole system sealed

Exhaust accessories are the connectors, cutouts, flanges, hangers, clamps, slip-ons and hardware that tie an exhaust system together and let it seal, flex and mount properly. Anyone who has swapped a system knows the fabrication almost never lives in the big tube - it lives in these pieces. A leaking flange or a cheap clamp will hiss and rattle no matter how good the muffler is, and an electronic cutout gives you a valve to open the system up when you want it. This is the category you raid to actually finish the job.

What ThreePiece stocks

There are 110 products in this category, drawn from 23 brands. Vibrant dominates the count with 61 items - the bread-and-butter fittings and hardware - followed by Vance and Hines (6), Bike Master (5), Ticon (4), Kooks Headers (4), and a run of tuner-focused names like CORSA Performance, QTP, HKS, Invidia, AWE Tuning and Granatelli Motor Sports. Prices currently run from $4 to $1,239 - that's the live range for what's in stock right now, not a fixed promise. At the top sits the AWE BashGuard for the 4th Gen Toyota Tacoma; a step down you'll find the Vance and Hines chrome slip-on for Harley-Davidson Softail and the Granatelli 3.0in stainless electronic dual cutout.

How to choose

Start with the job. If you want a switchable open/closed system, an electronic cutout like the Granatelli is the piece to buy - it's stainless and priced accordingly. If you're piecing a system together, the Vibrant range covers the cheap-but-essential end: flanges, clamps and connectors where a few dollars each adds up. Turbo and forced-induction cars often need a specific outlet - the Invidia Evo turbo outlet is that kind of part. Motorcycle riders buying a slip-on such as the Vance and Hines unit are choosing a near-complete accessory, not a raw fitting. The honest trade-off is scope: a $4 clamp does one small thing well, while the four-figure pieces are effectively finished sub-assemblies. Match the part to how much of the job you still have left.

What else you need

Accessories rarely go in alone. Pair them with the right core system from Cat-Back Exhaust, Axle-Back Exhaust Systems or Mufflers. If you're building from tube up, look at Exhaust Pipes, Exhaust Flanges and Headers, and finish the visible end with Exhaust Tips. Everything sits under the main Exhaust section.

Fitment and ordering

Only 11 of these products carry vehicle fitment data - covered makes include Toyota, Chevrolet, Volkswagen, Subaru, Mitsubishi and Harley-Davidson, on vehicles like the Chevrolet Corvette, Toyota Tacoma, Toyota GR Corolla, Volkswagen GTI, Mitsubishi Evolution and Subaru STI, across model years from 1992 to 2024. Many accessories are universal hardware, so confirm size and thread before you order. Not sure a part fits? Call fitment help at 813-535-5801 or use our contact page. All orders ship free, and Affirm and Katapult financing is available on the bigger buys.
