Inline Tube is the premier reproduction brake & fuel line company and is now taking its tube manufacturing to the next level and manufacturing select preformed exhaust systems.  We have been bending tube for over 18 years and making under chassis parts that have set the bar to be the industry best.   Our state of the art computer benders and laser scanner allow us to duplicate original parts with uncompromising accuracy.

All systems are mocked up on actual factory stock cars and pre-fitted.  Our systems come in the stock size and shape of the factory originals or optioned slightly oversized. All systems are made off our exclusive computer angle exhaust bender. This information is stored in the computer so bending is exact every time. Our systems feature a galvanized factory finish complete with flat spots and factory style exhaust flanges. Our exhaust pipes install with the exact factory plated hangers so there is no drilling or generic hanger placement. Our mufflers are a factory stock appearing flow through design with low restriction so you have a slight rumble and plenty of flow.  It is the way it should be complete and correct.
