Shelby GT350/R Test-Pipes

With a smooth flowing design, fitment, and just as important as performance; quality – B-Line Motorsports aims to set our Shelby GT350 test-pipes above all others.

With construction being from 100% 304 stainless material, thick flanges are incorporated followed by a smooth gradual transition for ultimate flow. OEM style damping mounts have been designed, laser cut, and added to mimic OE vibration absorption. To handle the increase of added exhaust flow, A “CEL” (check engine light) work around has been integrated to help in the aid of preventing the ECU from triggering an unwanted diagnostic code. Finally, everything from this point is surface finished then completely TIG welded, adding to the overall appearance, quality and performance.


For mid 2017 and up models, the OEM vibration dampers attached to the factory catalytic converters are no longer removable / reusable. B-Line Motorsports is pleased to announce that we have worked out a solution for this.


Note: Due to demand part is approximately 3 weeks out from date of purchase. 


Designed, Engineered, & Manufactured in house in the USA!


important: Selecting 2017 and later model years will automatically add the vibration damper to your order.


On rare occasion, some vehicles might exhibit a check engine light. If this does occur please contact us as we may be able to assist you in resolving it.


Test-pipes are for off-road use only, never intended for public highways or pollution controlled vehicles.
