BORLA's
XR-1® Raceline products are the choice of today's hottest
drag and track racers. Featuring a patented uninterrupted-flow
design, BORLA's
XR-1® mufflers actually outflow a straight piece of pipe
in repeated testing.
XR-1® race products are made in the USA and constructed of aircraft-quality
T-304 stainless steel for tough track durability. They meet
the strictest noise requirements and use sound-absorbing stainless
steel packing to protect against burnout. Hands down, BORLA
XR-1® Raceline offers the best balance of sound and power.
