The Stainless Works 2-1/4" four-way merge collector is a TIG-welded reverse-cone unit with 2-1/4" slip-fit primaries and a 4" OD outlet. Constructed from stainless steel for corrosion resistance, it channels exhaust pulses efficiently into the larger outlet. TIG welding ensures durable joints while the slip-fit interface eases installation in custom exhaust fabrications; these collectors are built for lasting service.
